Peak Scientific’s Solaris XE can deliver up to 35 L min–1 of nitrogen, at purity levels of up to 99.5% making it suitable for LC-MS applications.
Shimadzu Scientific Instruments has introduced the Nexera Mikros Microflow liquid chromatography mass spectrometry system covering the complete range from microflow to semi-microflow. System configuration options include a direct injection system for sample volume-limited analyses for rapid and highly sensitive micro LC-MS analysis without sample loss. A trap and elute system is available for analyses with larger injection volumes or when some degree of sample cleanup is desirable.
An LC-MS/MS method for food allergen testing has received First Action Official Method classification from AOAC International.
Edwards has introduced the air-cooled nXLi dry vacuum pump range, which provides a small footprint with quiet operation.
Scientists from the EU’s Joint Research Centre (JRC) have carried out a multi-year study based on comparative metabolomics combined with chemometrics on carrots coming from different agronomic environments. The results highlight the potential of metabolomics fingerprinting for organic food authentication purposes.
