Application Notes: General

Essential oils have been a staple of the food, fragrance, and health markets for many years. Owing to their unique composition, essential oils can be used for a variety of applications.

What you will learn: - How miniaturization can be applied to gel permeation chromatography - Considerations and benefits of the approach for size-based separations

µPAC™ technology has been used for analysing HCP impurities originating from recombinant expression systems used in the production of mAb based biotherapeutics.

All data is a cGMP record, as regulators enforce requirements to ensure the integrity of laboratory data. Find out how LabVantage Solutions can aid in compliance.

• QuEChERS vs. a modified method with the Geno/Grinder for pesticide analysis • Stable isotope analysis for the testing of food product origins • Arsenic testing in hard ciders

• Characterizing cannabis • Terpenes analysis using headspace solid-phase microextraction and GC–MS • LC triple-quad and GCxGC-TOFMS for efficient cannabis testing.

With Antec Scientific’s new ground-breaking µ-PrepCell-SS, electrochemical reduction of disulfide bonds in peptides, proteins, mAbs, and other biopharmaceuticals becomes possible routinely in LC-MS workflows. • Fast and efficient reduction of S-S bonds • Robust on-line reduction in top-down and bottom-up Proteomics • Reagent free, no interfering DTT or TCEP, ideal for HDXMS • Superior peptide sequencing and S-S bond assignment

An effective enrichment method for glycopeptides were developed based on iSPE®-HILIC material. It opens a range of opportunities for glycoproteomics research.

Testing shows that Restek Long-Life ESI electrodes for Sciex Turbo V sources provide equivalent chromatographic performance to original equipment manufacturer electrodes over significantly longer lifetimes.

An efficient separation of polar and nonpolar lipid representatives was achieved utilizing iSPE®-HILIC material. The lipids were separated according to their polarity.

• Disaster recovery and business continuity plans are crucial for companies. • Most laboratories are not confident in their recovery and continuity plans. • When seeking solutions for system failures, consider regulatory guidelines.

Note discusses how labs are coping with the worldwide helium shortage.

In this application we show how to achieve the best separation and sensitivity for insulin UHPLC-MS analysis by using formic acid as a weak ion pairing agent.
