WEAR Conference 2019

By Saji George

Appropriate product testing should be set in place by any manufacturer of consumer goods to ensure quality, reliability and high-quality products. It is important to test the functionality of the product but it is also wise to test the product in the type of system in which it will be functioning. To determine the endurance without waiting out the life of the product, stress testing should be an integral part of product testing protocols. Pickering Laboratories’ artificial body fluids play an important role in these stress tests.

The WEAR Conference brings together leading smart fabric and wearable device experts. Attendees at this conference will include business development managers, chief innovation officers, creative directors, material scientists and developers of wearable consumer products and their components. Pickering Laboratories Inc. is proud to be sponsoring WEAR 2019 in Seattle, Washington; Saji George and Rebecca Smith will both be in attendance. We are looking forward to meeting with our existing customers and making lots of new connections with industry leaders in this exciting field!

Looking Ahead to NACRW 2019!

By Sareeta Nerkar

The North American Chemical Residue Workshop (NACRW) conducts an annual meeting catered to scientists who are particularly interested in trace level analysis of pesticides, veterinary drug residues and other chemicals in food, animal feed and environmental samples. Formerly named the Florida Pesticide Residue Workshop (FPRW), this year marks the 56th Annual Conference!

Two of our research chemists will be traveling to Naples, Florida from July 21-24, and they hope to get a chance to meet customers face-to-face and compare notes on the latest research and upcoming industry needs! Sareeta Nerkar will be joined by Maria Ofitserova in representing Pickering Laboratories at the meeting. In addition to sponsoring a luncheon, Sareeta and Maria will be hosting a vendor seminar on Wednesday, July 24 that will include the latest post-column applications, including Mycotoxins Analysis in Hemp and additional exciting news.

Sareeta is also looking forward to her oral presentation Tuesday, July 23 on Improved Extraction and Cleanup Prior to HPLC Determination of Glyphosate in Food Samples. She will be discussing a simple and robust method for the analysis of Glyphosate at sub-ppm levels in different kinds of food. The accelerated sample preparation improves sample throughput and reduces the cost of analysis for busy testing laboratories using the post-column Glyphosate method!

The Pickering Laboratories poster for the conference this year is on the Analysis of Mycotoxins in Cannabis Plants and Cannabis-containing Products, so please look for Sareeta during the poster session!


Come One, Come All to NEMC 2019!

By Rebecca Smith and David Mazawa

This year the annual National Environmental Monitoring Conference (NEMC) heads south to Jacksonville, Florida, where chemists and environmental regulators from around the country will gather from August 5-9, 2019.  The August weather and the technical program will both be heating up as David and Rebecca check out the latest research in environmental monitoring and methodology. 

Please stop by our booth to chat with us about the latest post-column developments and newest product testing solutions.  Or, even better, come find us at the New Technology Showcase on Tuesday, August 6th from 3:00 – 5:00 pm!  David will be joining other instrument manufacturers to discuss the latest innovations in analytical instrumentation. 

Finally, we’re excited to be included in this year’s selection of drinking water poster presentations!  David and Rebecca will gladly discuss our poster with you when we see you at the show.  For reference, it is titled: HIGHLY SENSITIVE ANALYSIS OF CHROMIUM (VI) IN DRINKING WATER BY ION CHROMATOGRAPHY (IC) WITH POST-COLUMN DERIVATIZATION AND UV/VIS DETECTION.

Pittcon 2019: Recap from Philadelphia

By Mike Gottschalk and Maria Ofitserova

Philadelphia, Pennsylvania was the site of Pittcon 2019 and Pickering Laboratories was one of over 1,000 exhibitors at the convention center.  As Philadelphia is centered between the New York and Washington D.C., the location brought us close to many of our customers and soon-to-be customers particularly in the pharmaceutical industry. 

Maria, Rebecca and I spent three days exhibiting and providing information on the latest post-column derivatization applications, not to mention showing off all the new products in our Pickering Test Solutions product line.  Our promotional giveaways were a big hit and we greatly underestimated how popular the Pickering yoga mats and exercise balls would be!  Hopefully you stopped by our booth early if you enjoy a good workout while you travel.

We are always pleased by the amount of interested people who stop by to discuss our Product Testing Solutions. We often hear “I didn’t know you made artificial perspiration?”  They will ask us to explain the many types of consumer products that need to be tested with perspiration as well as saliva, urine and other simulated body fluids. You might have noticed that for the last three years, we’ve tried a “sweaty” theme for our show giveaways!  It’s been a great way to promote discussions about product testing and how important it is for almost every industry to evaluate materials with artificial bodily fluids.

One of the new focuses for our post-column research and development has been the growing market for Cannabis related products and the testing of Cannabis.  This field (pun intended?) has shown increasing and sustained interest in cannabinoids and contaminants testing.  There’s good interest in the post-column applications we’ve developed for these matrices, and it reflects the industry demand for verified testing applications.  Highlighted at the show were our applications for the Analysis of Mycotoxins in Cannabis and the Analysis of Cannabinoids in Cannabis and Cannabis-containing Edible Products.

While at Pittcon, we hosted a daily raffle at our booth.  Each expo day, we chose a winner for a pair of Bose “Sleepbuds” – noise cancelling earbuds specifically designed to help the wearer get awesome sleep!  Congratulations to our winners William Collin from General Motors, Brent Hanlin from ALS, and Keith Saroka from the Interboro School District.  This picture really captures how pleased these lucky winners were!

Thank you to everyone who came by the booth to visit with us in Philly this year – we had so much fun chatting with you all!  And of course, if you ever want more information between shows, we’re always adding fun new things to our website and introducing new products in our quarterly newsletter.  Please email support@pickeringlabs.com to discuss any new applications with Maria or another of our amazing chemists!

Welcoming the New Season… and the New Manager!

By Rebecca Smith, Tony McIsaac and Maureen Takagi

Summer is almost upon us and things have been heating up at Pickering Laboratories!  We are so excited to introduce the newest member of our team and talk a little bit about what has been happening behind the scenes here around the lab.

Over the last 20+ years, many of our customers, vendors and industry colleagues have gotten the opportunity to know Tony McIsaac, our Vice President of Production.  Tony has long managed our production team and coordinated all things manufacturing at Pickering.  He’s very personable and friendly, so if you ever meet him at Pittcon or when visiting our facility, he might have made an impression (and who could forget that mustache?!).

These days, now that he’s four grand kids deep, Tony has turned his eyes towards coordinating a whole new chapter in his life!  He’s beginning a gradual transition towards retirement, first moving from manager to individual contributor and then from full-time to part-time (come this fall).

When a company like ours is lucky enough to have continuity at such an important position for so many years, successfully transitioning to a new manager requires a lot of planning!  Not to mention cross-training!  So, while Tony won’t be fully retiring until 2020, the process of replacing him is already in full swing around here. 

Maureen Takagi, Production Manager Extraordinaire

Enter Maureen Takagi, our newest hire!  Maureen has joined the Pickering team as our new Production Manager and she’s primed to take over Tony’s managerial responsibilities.  Maureen is very experienced in the instrument manufacturing world and has launched right into her new role with a full head of steam!  What an exciting time for our whole company!

Maureen comes to us after a long tenure with her previous employer where she managed a DPSS laser manufacturing group. Professionally, Maureen has a keen interest in continuous

improvement and recently earned her Lean Six Sigma Green Belt.

When not at work, Maureen is teaching Spin® classes and participating in the YMCA annual fund-raising campaign to support youth programs for under-funded families.

We’re hoping to convince Maureen to brave the weather and travel with us to Chicago for Pittcon 2020 next March, where many of our customers and vendors would get a chance to meet her. If you just can’t wait, please feel free to reach out via email or stop by the lab if you’re in the area!


Maureen and Tony, celebrating with gusto in the laboratory (but where’s the PPE?!) … Cheers, you two!

Congratulations to our quiz winners!

Thank you all for your submissions! 




The correct answers for the Glyphosate Doublet Peak quiz:

The Glyphosate ‘doublet’ is caused by injecting a sample at basic pH.  An improperly buffered sample extract at a large injection volume will not mix with the mobile phase sufficiently to create the acidic pH necessary for Glyphosate to be at the proper single charge state, impacting the interaction between Glyphosate and the active sites on the column resin.  Adding a couple drops of RestoreTM (pH 1.3) to the sample before injection will eliminate the ‘doublet’ and return proper peak shape.
