Corporate Retrospective 2007: Pickering
Pickering Laboratories began in September 1980.
Pickering Laboratories began in September 1980. We had a single, patented product, a ready-made, stable ninhydrin reagent that was marketed to dedicated amino acid analyzer users. Incorporation followed in December 1981 and soon after, the product line included the columns, eluants, and hardware to allow for gradient amino acid analysis on any ternary, single-temperature HPLC.
Our specialty in bringing post-column derivatization to modern HPLC now includes official USEPA, AOAC, FDA, and a large variety of custom methods. The main focus for these protocols, recognizing that chemical reactions are involved, is controlling the purity of the chemicals. A purity of 99% may sound good, but depending on the intended use, the 1% can be and often is boss. That is why general chemical suppliers will not warranty any chemical for any use. However, pure chemicals react inexorably, thus we are able to provide "Guaranteed Chemistry" by controlling what we exclude from the chemicals and formulations.
Throughout the years, our company has kept its focus on developing new post-column methods and reagents. The latest include specific post-column reagent for sulfonamide sweeteners such as saccharin, acesulfame K, and cyclamate; a multi-residue mycotoxin method, and improved protocols for nitrite/nitrate and bromate analysis. And introduction of the latest model of our post-column derivatization instrument with its unique features such as pulse-free syringe pump and temperature gradient column oven allows us to bring our customers unmatched sensitivity and selectivity of analysis.
Though Pickering Laboratories is best known for its post-column derivatization presence in the analytical market, we have never been limited to chromatographic applications. We developed the first artificial human eccrine perspiration with ingredients and amounts based on analytical data. Because perspiration can damage contacted surfaces, many industries have need to use artificial perspiration to test their products. Our formulation is now available from Crime Sciences, Inc. for quality control in forensic determination of latent fingerprints on documents.
We will continue utilizing our expertise in preparing pure chemicals and chemical formulations to help our customers find the correct solution for guaranteed chemistry.

The Complexity of Oligonucleotide Separations
January 9th 2025Peter Pellegrinelli, Applications Specialist at Advanced Materials Technology (AMT) explains the complexity of oligonucleotide separations due to the unique chemical properties of these molecules. Issues such as varying length, sequence complexity, and hydrophilic-hydrophobic characteristics make efficient separations difficult. Separation scientists are addressing these challenges by modifying mobile phase compositions, using varying ion-pairing reagents, and exploring alternative separation modes like HILIC and ion-exchange chromatography. Due to these complexities, AMT has introduced the HALO OLIGO column, which offers high-resolution, fast separations through its innovative Fused-Core® technology and high pH stability. Alongside explaining the new column, Peter looks to the future of these separations and what is next to come.
Frontage Laboratories Streamlines their Product Lifecycle Management with NuGenesis™ LMS
January 9th 2025Frontage laboratories wanted to improve the efficiency and quality of their operations and invest in ways to streamline their workflows. They implemented Waters NuGenesis™ Lab Management System (LMS) to progress their digital transformation journey and combine synergistic data, workflow, and sample management capabilities to support the entire product lifecycle from discovery through manufacturing.
