Selection of Membrane / Devices for Dissolution Testing

Companies including Bristol Meyers Squibb and Pfizer have been laying off workers, which could be worrisome for analytical scientists.

Ultrahigh-pressure liquid chromatography coupled to high-resolution mass spectrometry (UHPLC-HRMS) had been previously proposed for untargeted lipidomics analysis, but this updated approach was reported by the authors to reduce run time to 4 min.

Biozen dSEC-7 accurately resolves AAV serotypes 5, 8 and 9 monomer from aggregates in under 10 minutes with consistent results across different mobile phase conditions.

Photodegradation of plastic products is known to accelerate weathering and the resulting release of chemical additives and particles to the environment, however these processes are complex. Here, eight different plastic consumer products were leached in double-distilled water under exposure to strong ultraviolet (UV) light for ten days, and the chemical composition of the leachates was compared to their respective dark controls. The leachates and plastic particles were investigated with a wide battery of chemical-analytical tools to broadly characterize the underlying processes and possible hazards. These covered (a) metal(loid) analysis, (b) microplastic analysis, (c) analysis of >70 organic target analytes and (d) nontargeted screening of the extracts.
