App Notes

The analysis of trace-level VOCs in drinking water using the headspace–trap sampling mode of the Centri® automated sampling and concentration system.

Monoclonal antibodies (MAb) are immunologically active proteins.

In this report, useful tips for optimisation of ion exchange chromatography methods for oligonucleotides are provided.

Sphingolipids are major components forming biological membranes, and they serve as intracellular signalling molecules.

Monoclonal antibodies (MAbs) are immunologically active proteins, which bind specifically to certain cells or proteins.

Amyloid β (Aβ) are peptides of 36–43 amino acids that are derived from the amyloid precursor protein (APP) by cleavage with β- and γ- secretase.

In this application YMC-Triart Bio C4 was used to analyse a reduced monoclonal antibody and a reduced ADC mimic with formic acid or TFA as additives.

This study presents a method for comparison of related impurities in a brand and a generic over-the-counter (OTC) acetaminophen drug.

Assessing SPME and high‑capacity sorptive extraction

The identification and quantitation of volatile organic pollutants in air can be challenging, largely because of the complexity of the samples.
