Extraction of air sampling filters for the determination of dioxins using BUCHI’s SpeedExtractor E-914

A 2015 Innovation Award-winning “fastGC” module enhances proton transfer reaction time-of-flight analyzer performance by adding an optional near real-time chemical pre-separation step. Here’s the story behind its development.

The traditional approach of designing experiments by changing one factor at a time is outmoded.

Can a new slippery surface for Raman scattering open the door to routine single molecule detection?

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 Analytical Scientist Innovation Awards (TASIAs) return for a third consecutive year to recognize 12 months of innovation from companies big and small.

Could NASA’s “chemical laptop” breathe new life into the search for extraterrestrials?

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.
