NACRW 2018 Report

Pickering Laboratories exhibited at the North American Chemical Residue Workshop (NACRW) in Naples, Florida on July 22-25, 2018. Formerly the Florida Pesticide Residue Workshop, this annual event is focused on trace level analysis of pesticides, veterinary drug residues and other chemicals found in food, animal feed, cannabis and environmental samples. 

Unique to NACRW are the technical sessions, as they are informal and collaborative to encourage conversation and sharing among the conferees. It’s an exciting workshop where every year attendees come away with insightful new information and presenters can get great feedback on their own research.  Sareeta Nerkar had exactly this opportunity at her oral presentation of “Mycotoxins in Animal Matrices, Food and Feed” which was well received. There is considerable interest in Pickering’s method for mycotoxins analysis because it is robust, established and economical.  Additionally, Sareeta presented our poster “Analysis of Polyether Antibiotics in Animal Feeds by HPLC with Post-Column Derivatization” during the poster session.

As a member of the NACRW organizing committee, Sareeta chaired the social committee this year. She’s pictured here at the Mediterranean-themed dinner event featuring drinks, games and prizes!

The west coast of Florida was experiencing an unusually long red tide event while the workshop was in session. The hotel was about a mile inland, so the health effects were not experienced by the hotel guests although they present a challenge for local residents and beachside visitors. There were some, though, who appreciated the event on a different level! After a presentation on brevetoxins, an attending graduate student related that he took the hotel shuttle to beach in order to experience his first red tide event. It was so strong that it made his eyes tear and caused coughing – he was thrilled. Other attendees perhaps made less use of the beach shuttle this year than at previous workshops.

At our exhibit, Mike Gottschalk offered literature on several post-column environmental testing applications including Glyphosate, Gluphosinate, Carbamates, Mycotoxins and others. Mike and Sareeta hosted a raffle for an Amazon Kindle this year, and we want to congratulate Thomas Scott from Diversified Laboratories on his winning entry!

Our exhibit also included the Pickering Test Solutions product line for consumer product testing. We are excited by how much interest there is in artificial body fluids from laboratories needing standardized solutions for their industry testing requirements.

For us, the workshop was a great success. We hope you enjoyed attending as well! We are already looking ahead to next year’s workshop, when we will have more exciting research to share.

NEMC 2018 Report

Pickering Laboratories, Inc. exhibited at the National Environmental Monitoring Conference (NEMC) in New Orleans from August 6 to 10, 2018. We enjoyed the great posters and talks ranging from technical issues monitoring environmental samples to challenges with cannabis testing. We hosted a booth where we met new leads and supported some of our long-time customers. Handfuls of fidget spinners, cooling towels, emoji pens and of course our trustworthy calibrated rulers were gifted to attendees that stopped by. Rebecca Smith presented our poster about Glyphosate in Foods. The method abstract can be downloaded here. Also on display at our booth were handouts for our Product Testing Solutions product line.

Here’s David Mazawa, ready to discuss the latest post-column applications with show attendees:

It was great catching up with our customers and meeting some new people at the conference!  We hope everyone who attended enjoyed the technical talks and New Orleans food as much as we did.

The next NEMC meeting will be held in Jacksonville, Florida from August 5 to 9, 2019.  We’re looking forward to it!

AOAC 2018

Held in August, the 2018 AOAC International Meeting in Toronto, Canada was an excellent opportunity for Pickering Laboratories to be closer to our customers in Canada and the northern United States. The annual AOAC meeting brings experts in food safety, food integrity and public health together to develop and validate analytical methods. This year, Canadian Governmental Laboratories were in significant attendance as well.

Mike Gottschalk and Maria Ofitserova met with existing customers and other attendees interested in our instrumentation and consumables. We exhibited the latest in post-column applications at our booth and sponsored a Vendor Session on our most recently developed method.  We also answered questions our growing Pickering Test Solutions product line. The artificial body fluids we manufacture for research and consumer product testing generated a surprising amount of interest from attending laboratories needing standardized solutions for testing various products.

At our Vendor Session, Maria Ofitserova presented our newly developed and validated method: “Amino Acids Analysis in Dietary Ingredients and Supplements by High-Performance Liquid Chromatography and Post-Column Derivatization.” This method follows the requirements specified by the AOAC Stakeholder Panel on Dietary Supplements and the presentation generated many interesting discussions with representatives of contract laboratories running amino acids analysis.

Maria Ofitserova also continued her work as part of the AOAC Stakeholder Panels and Expert Review Panels. Stakeholders meetings focused on the needs of consumers and industry leaders in the areas of food analysis, supplements analysis and baby formula analysis.

The Pickering Laboratories PINNACLE PCX post-column derivatization instrument is well known for analysis of Amino Acids, Mycotoxins, Glyphosate and many other analytes. Our chemists’ hard work fits very comfortably within the mission of AOAC to research, develop and validate analytical methods.

New Application Notes

ANALYSIS ANALYSIS OF MYCOTOXINS IN CANNABIS PLANTS AND CANNABIS-CONTAINING PRODUCTS OF MYCOTOXINS IN CANNABIS PLANTS AND CANNABIS-CONTAINING PRODUCTS

State regulations have established maximum allowed levels for Mycotoxins in Cannabis-containing products sold to consumers at the following maximum levels: levels for total Aflatoxins G1, G2, B1 and B2 are set at < 20 ppb and levels for Ochratoxin A at < 20 ppb. Pickering Laboratories developed an easy and sensitive method to analyze Aflatoxins B1, B2, G1, G2 and Ochratoxin A in cannabis plants and edible products. Mycotoxins are isolated using immunoaffinity clean-up columns and analyzed with fluorescence detection. To increase sensitivity of Aflatoxins B1 and G1, an in-line photochemical reactor is installed before the detector. This method utilizes standard HPLC equipment and allows testing laboratories to easily determine Mycotoxins at levels below the limits established by state regulations.

ANALYSIS OF AMINO ACIDS IN DIETARY INGREDIENTS AND SUPPLEMENTS

Analysis of amino acids using cation-exchange columns and Ninhydrin post-column reagent is well-establish methodology that is recommended by the European Pharmacopeia. Pickering Laboratories developed and validated a post-column method for amino acids analysis of dietary supplements that is sensitive, selective and can be used without modifications to analyze capsules, tablets, drinks and other samples. Accelerated methods are available for samples with a limited number of amino acids.

Previous Articles on Glyphosate
Pickering Laboratories offers a post-column method for Glyphosate analysis that has been the industry standard for many years. Our methodology is simpler and more sensitive than LCMS, not to mention less expensive. Please contact us to speak with a chemist about post-column instrumentation or for tips and tricks to improved sample preparation, lower detection limits, or if you’ve got a new sample matrix in mind.

Reagent and Gas Line Clips

Dear valued customer,

You may have noticed that the stiff tubing of the reagent line will sometimes unscrew itself from the white adapter and cap. This will usually end up in a big mess. We have found that securing the gas line and reagent lines together will secure the reagent line and prevent it from unscrewing on its own. We will be launching the Reagent and Gas Line Clips on Oct 8, 2018. Any Vector or Pinnacle manufactured on or after this date will include the new clips. The gas and reagent line clips will also be included with all reagent caps. You can also order packs of two with the ordering information below:
