Analysis of Nine Nitrosamines Relevant to Occupational Safety by Ion
This study aims to analyse nine nitrosamines relevant in the field of occupational safety using a gas chromatography-drift tube ion mobility spectrometry (GC-DT-IMS) system.
Development, Optimisation, and Pre-Validation of a Gas Chromatography—Ion Mobility Spectrometry Method with Preliminary Twofold Enrichment for the Sensitive Detection of N–Nitrosamines in Drinking Water
This study aims to develop, optimise, and evaluate a gas chromatography-drift tube-ion mobility spectrometry (GC-IMS) based method with a twofold enrichment strategy consisting of solid phase extraction (SPE) followed by in-tube extraction (ITEX) of the eluate for nine different nitrosamines in drinking water in order to offer a sensitive alternative to the current state of the art.
Expanding Capabilities in Multi-Residue Pesticide Analysis Using the LCMS-8060
Using the Shimadzu Pesticide MRM Library and the Restek Raptor Biphenyl LC column, a single multiresidue LC-MS/MS method was developed for 646 pesticides.
Appropriate Instrumentation for the Chemical Analysis of Cannabis and Derivative Products: Part 1
For the uninitiated, analytical instrumentation can be a confusing mix of abbreviations and hyphenation. In this series of articles, we break down and explain in practical terms what instruments are appropriate for a particular analysis and what to consider when choosing an instrumental technique.
Area-Selective Atomic Layer Deposition of ZnO on Si\SiO2 Modified with Tris(dimethylamino)methylsilane
Delayed atomic layer deposition (ALD) of ZnO, i.e., area selective (AS)-ALD, was successfully achieved on silicon wafers (Si\SiO2) terminated with tris(dimethylamino)methylsilane (TDMAMS). This resist molecule was deposited in a home-built, near-atmospheric pressure, flow-through, gas-phase reactor.
Analysis of Furan and Alkylfurans in Food Commodities by SPME Arrow GC-MS
Food safety labs can significantly improve productivity by using SPME Arrow to test diverse sample types containing furan and alkylfurans at different levels compared to using legacy headspace GC methods or methods that require both headspace and SPME.
Simultaneous Analysis of Alcohol Metabolites and Barbiturates by LC-MS/MS
This hydrolysis-free method for the simultaneous analysis of alcohol metabolites and barbiturates allows all target analytes to be reported from a single LC-MS/MS method.
Fast, 3.5 Minute Analysis of Psilocin and Psilocybin in Urine by LC-MS/MS
This application note details a fast, 3.5-minute LC-MS/MS method for quantitative analysis of psilocin and psilocybin in human urine.
Analysis by LC-MS/MS of polar pesticides in fruits and vegetables using new hybrid stationary phase
A European Reference Lab evaluation of Raptor Polar X LC columns for the QuPPe method “Methanol extraction of polar pesticides without acidification.”
Meet Requirements of EPA Method 537.1 PFAS Analysis with Contaminant-Free Workflow
This application note demonstrates a contaminant-free workflow for EPA Method 537.1 PFAS analysis. No background interferences were present and good recoveries were obtained for all target analytes.
