Differentiation of Illicit D-Methamphetamine from Over-the-Counter L-Methamphetamine by LC-MS

Many labs are facing helium supply difficulties and rapid price increases as a result of the helium shortage. Lab managers are therefore looking for alternative carrier gases and for many GC applications, hydrogen provides an excellent alternative to helium.

A collaboration between Markes and the German Federal Institute for Materials Research and Testing (BAM) has resulted in a new test scheme, featuring TD–GC–MS sampling & analytical instrumentation, for assessing emissions of artefact-damaging chemicals from the materials used in museum display cases.

This application demonstrates the time-optimized separation of the harmful substances bisphenol A (BPA) and bisphenol F (BPF), which are still commonly used by the plastic producing industry. The analysis was carried out with excellent linearity and required less than 1 minute using a PLATINblue UHPLC system and a BlueOrchid C18 column.

Proteomic research facilities and laboratories are facing increasing demands for the integration of biological data from multiple '-OMICS' approaches.

This Application Note describes the determination of copolymer levels in polyethylene (PE) and polyvinylacetate (PVA) pellets using NIRS.

Historically, within Syngenta quantitative and qualitative LC-MS analysis have been performed in parallel. Last year the Q-E was purchased to support cross-functional quan/qual projects with diverse applications throughout R&D.

Worldwide helium demand far exceeds current production levels. For many gas chromatography applications, the switch to hydrogen is painless. What’s stopping you?

In December 2000, the European Water Framework Directive (WFD) came into force and became part of UK law in December 2003. The underpinning basis of WFD was ecology driven, with the key mandated objective to provide for the planning and delivery of a better aquatic environment.
