Fields & Applications

Usually, PLA and PLGA are based on monomers from renewable sources, so are considered “green” polymers. By selecting different molecular weights, different ratios of lactic:glycolic acid and different molecular structures, some properties such as degradation or drug release rates can be tailored to meet application needs. GPC/SEC analysis is an ideal tool for monitoring samples during material synthesis, production of parts and in degradation studies.

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.

Criminals “sweating it out” beware: a new amino acid test can tell male from female fingerprints

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.

Optimizing oxygen delivery improves stem cell treatment of peripheral artery disease.

A growing target list, increasingly complex matrices, and the need for low limits of detection can make our field seem like an uphill treadmill.
