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.
Rapid Screening Analysis of On-Line Purified Residual Pesticides in Crop Extract Using Accurate Mass Information
In this article, an example of comprehensive analysis of residual pesticides in spinach using a Revive In-Line Sample Preparation (ILSP) and the quadrupole time-of-flight mass spectrometer LCMS-9050 is introduced.
Purification of Mineral Oil Aromatic Hydrocarbons and Separation Based on the Number of Aromatic Rings Using a Liquid Chromatography Silica Column. An Alternative to Epoxidation
This work presents a new purification approach based on liquid chromatography fractionation on silica using the same column and eluents as for the usual MOSH/MOAH fractionation.
Storing and Handling Volatile Residual Solvent Gases in Secondary Containers
These general guidelines can help extend the shelf life of volatile reference standards, improving analyte recoveries and assisting accurate quantification.
Simultaneous Analysis of Pesticides and Mycotoxins in Primary Processed Foods: The Case of Bee Pollen
This optimized LC-MS/MS method analyzes 282 pesticides and 8 mycotoxins in bee pollen.
Common light gas coelutions when using a GC packed column
Troubleshooting coeluting compounds during packed column gas analyses can be a difficult task. In this post, we look at the more common coeluting gas issues you may face and recommend steps to overcome them.
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.
