Fields & Applications

Two-dimensional mass spectrometry (2DMS) can be twice as fast as conventional methods in proteomic analyses

The molecular weight, molecular weight distribution and size of two common polymers are measured using SEC-MALS 20. Results from SEC-MALS and conventional calibration are compared and discussed.

Learn why isothermal titration calorimetry is a method of choice for accurate and precise determination of critical micellar concentration of surfactants for biochemical applications and find out how to analyse demicellization data from Isothermal Titration Calorimetry

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.
