Mass Spectrometry

The Pesticide Explorer Collection comprises four complete workflows that meet the challenges of modern pesticide residue analysis.

New analytical capability can have a significant impact on research direction.

Every year sees new chemicals added to the list of analytes that may need to be measured in a given sample. At the same time, environmental levels of many older pollutants may be in decline – but still must be measured.

In water analysis, direct injection of samples into your LC-MS/MS system (without sample preparation beyond filtration) is possible because of advances in instrumentation. However, matrix effects must be monitored carefully – and sometimes may even prove useful.

GSK and the RSC embark on a five-year partnership to bring GC-MS skills to Africa

A new LC-MS/MS screening method simultaneously detects a wide range of non-banned potentially performance enhancing drugs and masking agents in urine

Three years on, and our mission to record, celebrate and scrutinize analytical science is as strong as ever.

This application note will describe the analysis of a series of dextran samples ranging in molecular weight from about 1 – 650 kDa. Structural comparisons to other polysaccharides, gum arabic and pectin are presented. Initially discovered by Louis Pasteur in 1861, dextran is a polysaccharide that has found a variety of applications, primarily in the medical field, due to its minimal side-effects and solubility in aqueous media.

Coupling whole column imaging detection to a mass spectrometer for protein structure characterization is fundamentally challenging. Could a relatively simple capillary cartridge system unlock the potential?
