Pickering Laboratories in 2013

By Wendy Rasmussen

In recent years, we have released several new products and applications, and with still more on the horizon, it occurred to me that now would be a great time to summarize the Pickering of today – our mindset and our wide variety of products & applications.

Acai Berries
Acai Berries

No longer are we simply the “Post-Column Company”. We are the “Automated-Sample Antioxidants” company.  Think of us as the new “super fruit.” The Acai berry, or perhaps the new Chia Seeds (incidentally, we do have a post-column application for the identification & quantitation of  Antioxidants in a variety of matrices).

We are still very active, and we as a company plan to be here for many years to come. We are still the company founded on chemistry and a desire to to teach, to spread our technical expertise, to support our customers.

It’s been a few years now since Pickering began distributing and supporting our LCTech Product line.  The products have shown an ever increasing interest here in the US and in Canada (our official Sales Territory for this product line). We are very proud to offer these products and we hope we can develop it further in the future.

Historically, we have provided the back-end of an analysis (post-column derivatization). Nowadays, we can provide the front-end of analysis as well (the sample-cleanup).

In thinking about our product offerings, I realized that a simple list does not effectively show the scope of the products we have to offer in 2013 – primarily because we have a lot of overlap between products and product lines.  We’re not a vertical company in that regard.  I suppose one could say our product offerings are more circular in that many do not fall into a single distinct category.  I am a very visual person, and for me, a Venn diagram and our overall “product scale” really helped to understand and clarify our products:

On-Demand Webinar: Rugged and Sensitive Analysis of Mycotoxins in Food Matrices

If you missed the live webinar last summer, you can still hear the Webinar On-Demand! Just click on the links below to launch the presentation.
On August 14th, 2012, in collaboration with Thermo Scientific, Pickering Laboratories participated in a free webinar titled: Rugged and Sensitive Analysis of Mycotoxins in Food Matrices
 
The webinar was hosted by LC/GC Magazine and Thermo Scientific.

EVENT OVERVIEW
Mycotoxins are found in a staggering range of matrices, from grains to fruits, spices and nuts to animal feed. They are of major concern for their negative impact on the worldwide economy from product revenue losses, their toxicity to animals and humans, and their persistence throughout multiple food processing steps.Learn how Pickering Laboratories addresses this challenge and meets guidelines set by the FDA using sensitive and rugged Thermo Scientific UHPLC methods to effectively detect Aflatoxins as well as other key classes of Mycotoxins. These easy-to-use methods utilize immunoaffinity clean-up and post-column derivatization.

Also join us to discover the benefits of a Thermo Scientific LC-MS/MS method using automated Turbulent Flow sample extraction to separate Mycotoxins from complex food matrices. A highly efficient solution used in high throughput laboratories that eliminates manual sample preparation, improves method reliability and drives down cost per sample.

New Mycotoxin Cleanup Columns!

Also on display this year at Pittcon were the a couple of NEW! Mycotoxin clean-up columns available from Pickering Laboratories:
AflaCLEAN SMART
The immunoaffinity column AflaCLEAN SMART is designed for sample clean-up for subsequent Aflatoxin analysis. 
This columns is smaller than the other counterparts on the market – it uses only a fraction of the solvent and yet has 100ng loading capacity as specified by the AOAC methods. 
During extraction, dilution, washing, sample loading and elution, more than 80% of the solvents can be saved.

The final elution volume is only 400uL instead of the typical 2mL – and yet has the same final concentration as with other columns.  As most methods inject only 20-50uL of sample onto the autosampler, this volume is more than enough for analysis. 

These columns can also be used with the very convenient and affordable EluVac vacuum manifold.

DONeX
The DONeX column can be used in the sample preparation for the analysis of the mycotoxin Deoxynivalenol (Vomitoxin), which is often found on contaminated cereals and grains such as corn. 
The column is ideally suited to many common matrices such as corn, barley, oat, wheat, rye or cereal-based feed. The advantage of DONex is that these columns can also be used with complex matrices and one can stll obtain excellent recovery rates. 
DONeX is used with a sample load of 1 g for HPLC / post column / fluorescence detection or LC / MS.  By increasing the matrix load up to 4 g on column, users with HPLC / UV detection systems can reach detection limits as low as 200 ppb. 
Unlike our other Mycotoxin clean-up columns, DONeX is not an immunoaffinity column, and so it can be stored on the shelf and has an undefined shelf-life.
The DONeX clean-up column is based on a 3mL standard form and thus perfectly suitable for automated handling in the LCTech systems AcceCLEANTM and FREESTLYETM SPE
