COVID and Related PTS Products

By Maria Ofitserova, PhD

Pickering Test Solutions brochure coverFor several years now, Pickering Laboratories has continued to expand our line of Product Testing Solutions to include new synthetic body fluids or environmental solutions. We offer a variety of formulations of artificial perspiration, sebum and saliva for testing fabrics, plastics, dental alloys, medical devices, wearables and other electronics and many different consumer products.

The challenges that Covid-19 pandemic presents for the pharmaceutical and health care industry are staggering, and they impact manufacturers of medical devices and personal protective equipment as well. This brings into focus the need for artificial bodily fluids that can be used for both ongoing testing and tackling the new developments introduced by the Coronavirus crisis.

With that in mind Pickering has introduced new artificial saliva with mucin made according to ASTM methods E2720-16 and E2721-16. The official ASTM methods E2720-16 and E2721-16 specify artificial saliva formulation for the evaluation of decontamination procedures for surfaces and materials contaminated with human pathogenic viruses. The formulation has a mineral composition and pH close to human saliva and contains Mucin to increase the viscosity and lubricating ability of the solution. This artificial saliva can also be used for dental, drug delivery or pharmaceutical studies.

Pickering Laboratories also offers Artificial Lung Fluid called Gamble’s solution, which is used to simulate different interstitial conditions deep in the lung. Several artificial lung fluid formulations are described in literature and we would be happy to discuss customers’ particular testing needs and help you choose the correct solution for your specific application. As established manufacturers of medical devices are now joined by companies newly entering the health care space, we are proud to do our part in ensuring that medical equipment, such as ventilators, get properly tested.

Pickering’s staff is dedicated to working hard to support our customers, new and returning. We are recommitting to our promise of providing quality reagents and solutions quickly to support essential businesses and supporting manufacturers.

Brand-new Amino Acids Analysis Brochure

Amino Acid brochure coverNo other analytical technique, including pre-column derivatization followed by reversed-phase chromatography, has been shown to match post-column ion-exchange methods in accuracy and reproducibility. This is because the retention mechanism in ion exchange provides for chromatography that is almost completely matrix-insensitive. Simple sample preparation for native samples is an added benefit of the ion-exchange method.

With the alternative pre-column derivatization method, the prepared sample is subject to a chemical reaction that takes place in a very complex medium: the residual matrix. Matrix complexity produces both competition and inhibition in chemical synthesis, resulting in decreased reproducibility in peak areas and retention times. Very often, the pre-column method must be optimized for each different sample matrix. In contrast, ion-ex­change chromatography followed by post-column derivatization is intrin­sically more rugged and repeatable, since the matrix components do not retain on the cation-exchange column and have no influence on separation or derivatization of amino acids. The same method can be used for variety of samples, from plant extracts to serums or spinal fluids.

Pickering Laboratories, Inc. provides a complete solution to Amino Acid Analysis. We supply columns, eluants, reagents and post-column derivat­ization instruments that work seamlessly with virtually any modern HPLC, so we can guarantee the accuracy and reproducibility of the analysis. Our chemists will help you choose the method and instrumentation best suited to your requirements, work with you on any custom method optimization and offer continuous support in day-to-day operation.

Meet Our New Sales Manager!

By Rebecca Smith and Kevin McKeown

It is my great pleasure to have the chance in this newsletter to introduce Kevin McKeown, our new Sales Manager, to all of our customers, vendors and distributors!  When the COVID-19 pandemic finally recedes and life resumes some semblance of normalcy, we hope to have the chance for some of you to get better acquainted with Kevin in person…  Perhaps at trade shows or through an on-site visit (remember those?!) if 2021 shapes up sooner rather than later.  But in the meantime, this virtual introduction will have to do! 

Kevin McKeown with his two boys flying a kite on beach

In early November, Kevin joined the team and he has quickly come up to speed with the way of life here at Pickering Laboratories.  In his former role, he managed the Sales/Customer Service team at SPEX CertiPrep, where he spent the last 13 years of his career.  Coming on-board with a background in chemicals/consumables and already having established relationships with many of his current Pickering colleagues, this transition has been smooth sailing!  Kevin is experienced and enthusiastic – he can’t wait to interact closely with both direct end-users and valued dealers/distributors.  He is VERY excited to finally get back “on the road” again for Pickering!  In lieu of travel, Kevin has become well acquainted with “zooming” his way to a full social calendar.  He will surely enjoy getting to meet each and every one of you virtually and starting to put faces to names.

Kevin is the proud father of 4-year-old identical twin boys: Miles and Colin.  He lives in New Jersey, but he will quickly make sure that you know he’s born and raised in Delaware (also the location of his alma mater: The University of Delaware!).  In his free time, Kevin enjoys golfing, playing with his kids, reading, Super Hero movies, Notre Dame football and skiing (although that’s mainly before kids!).

Please give me a hand in giving Kevin a warm welcome!  You can reach out to him via email to say hello or schedule a quick zoom greeting.  Also, if you enjoy unsolicited pictures of kids (rather than puppies) he’s an excellent source for adorable photos!   

 

Pandemic Puppy Pictures

By Rebecca Smith

As I teased in the last quarterly newsletter introduction, when it comes to my personal life, I have spent the 2020 COVID-19 pandemic growing my household!  My fiancé and I are very pleased to have actually added not one but TWO pandemic puppies to our family this year.  We showed you a picture of our first puppy as a wee little tyke, before we’d even picked her up.  Now, our “little” Luna is six months old and weighs over fifty pounds already!  She’s going to be a big girl.

Here you can see her September vs December as a lap-pup:

Rebecca's puppy, Luna

Here are a couple more baby pictures of Luna, including her “kraken” Halloween costume:

Finally, here’s Luna as a big girl in December, right before she got to meet her new baby “sister” (also pictured is coonhound “auntie” Annabelle):

Luna grown up with old coonhound “auntie” Annabelle

Speaking of sisters, we’ve just returned from picking up Luna’s new baby sister!  Tiny little Terra is barely nine weeks old and cannot compete with her sister in stature just yet – but she’ll catch up soon enough!  She’s only been home for a few days but Terra is making her presence known!  Auntie Annabelle isn’t too interested in her just yet, but big sister Luna cannot wait until she’s big enough for tug-of-war.

Our newest addition, Terra:

While I absolutely love nothing more than showing off unsolicited pictures of my “kids,” I don’t want to steal the thunder from our other newsletter articles!  Suffice to say, if you’d like to see more puppy pictures or want to know anything else about the girls, just reach out to me by email or phone.  I’d love to say hello and talk about all things Swissy (or coonhound for that matter!).  I always enjoy seeing pictures from other dog moms too, so if anyone else has a pandemic puppy and wants to share pictures… send them my way!  Since the Coronavirus disruption seems determined to trickle into the beginning of 2021, I’d love to share cute or silly quarantine pictures of your pups with our Pickering team. 

Happy New Year to you and your families!  Wishing you a healthy and safe start to 2021! 

I’ll end with a “side-by-side” with Terra watching Luna watch their dinner preparations:

Socially Distanced Holiday Season

Season’s Greetings and Happy Holidays from the Pickering Laboratories Team!

By Christopher Nguyen

Most people would agree that 2020 has been a wild year. For us here at Pickering, we unanimously agreed that in light of this year’s events, the Pickering Team still needed to find some festive cheer despite (to spite?) the COVID-19 pandemic. 

So as the year came to a close, we celebrated the socially-distanced holiday season with one another from a safe distance and wearing our most festive outfits and masks. Here’s a look at our fun filled December! From pajama day to DIY tree ornaments, catered “box lunches” to secret Santa exchanges, we at Pickering Laboratories held on to the holiday cheer and closed out the year with smiles, joy, and laughter. Thanks, team, for the awesome year! Here’s to a great 2021!

From all of us here at Pickering Laboratories, we are wishing you all a wonderful, safe, and warm holiday, but more importantly, a safe and happy 2021!

Cheers!

The Answer to Chromatography Quiz #36

The answer is column temperature was set too low. Column temperature has a big affect on retention time stability. That it is why it is important to use a column heater for your analytical methods. We have used this principle to our advantage with our column temperature gradient methods. Our fast amino acid methods use a column temperature gradient where the temperature is changed throughout the run. This has cut some of our older run times in half. Please note that these methods can only be run on our Pinnace or Onyx PCX. No other post-column systems have our repeatable temperature gradient capabilities. See our amino acid method abstracts for more details: https://www.pickeringlabs.com/library/method-abstracts-2/

Flashy Fun Content Hitting the Web – Amino Acids Analysis and the Onyx PCX

By Maria Ofitserova

Onyx PCX workstationNormally, summer and fall would mark our busy travel season with several important conferences and trade shows to prepare for and attend. With the majority of conferences cancelled, rescheduled or moved to virtual platforms, we are staying close to home and focusing on supporting our customers as they navigate the fast-changing COVID-19 pandemic situation.

After introducing the Onyx PCX at Pittcon in March 2020, we are happy to report positive feedback from users of our newest post-column derivatization instrument. One of our goals when developing the Onyx PCX was to ensure a seamless transition of methods from the Pinnacle PCX to the new model. This allows companies to minimize validation steps when switching to the Onyx PCX and early customer responses show our efforts were worth it! Our extra attention to this during design is definitely being appreciated now by laboratories who already have the Pinnacle PCX system and are looking to expand or update their instrumentation.

The coronavirus pandemic continues to drive expansion of biotech research and manufacturing, with many companies and contract laboratories using amino acids analysis to identify and characterize biopharmaceuticals, determine purity and optimize manufacturing processes. The Onyx PCX is uniquely suitable for performing with excellence in regulated environments. Easy and robust operation, extensive record-keeping capabilities for troubleshooting as well as regulatory compliance and the ability to work with any HPLC setup makes the Onyx PCX a great choice for any laboratory running amino acids analysis.

By spending our time here at home and not presenting at various technical conferences, myself and the other chemists also had the opportunity to get creative and stretch beyond scientific posters into the world of marketing! We have created short videos highlighting the best features of Onyx PCX and capabilities of post-column amino acids analysis. You may have seen our LinkedIn posts about these videos – we are really quite proud of our work. Special thanks to David Mazawa for contributing the technical wizardry and to our graphic design consultant, Phil Mowery, for adding animations and sharpening up our look!

As always, at Pickering Laboratories we are concentrating on providing the best possible service and support for our customers. We have been hard at work strengthening our supply chain, adjusting production and inventory to meet the changing demand and collaborating closely with other companies to support our partners during this difficult time.  We know that our customers will appreciate our grit and resilience during 2020; we want to contribute to the best parts of what is working for your business as well.
