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.

Continual advances in liquid chromatography have raised the bar from high performance to ultra-high performance, resulting in increased analytical, instrument, and laboratory efficiency. What’s holding you back from investments in UHPLC technology?

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

What is the origin of stereochemical bias – terrestrial autocatalytic processes, extraterrestrial contamination or otherworldly intervention? Here, I review the gas chromatographic tools being used in the search for homochirality in space – the final frontier.

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.

This short and seemingly simple question belies the complexity of measuring – and interpreting – pH.

Can multi-angle light scattering aid in the characterization of proteins and antibody drug conjugates?
