  • Analysis of PBDEs in Sediment Using GC-MS/MS

    Polybrominated diphenyl ethers (PBDEs) are brominated flame retardants (BFRs) widely used in plastics. Due to their toxicity and persistence, their industrial production is to be eliminated under the Stockholm Convention. Contamination from PBDEs is widespread in the environment, including in sediments. In order to determine PBDEs in sediments, they need to be separated from a large amount of ...

  • Analysis of Opioids Using Isotope Dilution with GCMS-TQ8030 GC/MS/MS

    Development of methods for analysis of drugs of abuse has become a high priority for both forensic toxicology and law enforcement. The large numbers of individual drugs and new "designer drugs" has made method development for these compounds a significant undertaking. Gas chromatography mass spectrometry (GCMS) has been used extensively for analysis of drug residues and trace-level drugs in ...

  • A quick guide to oil analysis for engine test applications

    Reliability testing is a very important component of new engine development. Engineers need to fully understand and chart the engine lifetime performance under a variety of conditions before mass production may be considered. Many important performance data parameters are collected in real time through the many different types of sensors that are connected to the engine in the test cell and oil ...

  • GC/MS analysis of a complex sample in DCM using hydrogen carrier gas

    Labs worldwide have recently found that helium has been in short supply, leaving a number of labs without carrier gas. Added to this, helium prices have doubled over the past 10 years causing a number of labs to look into alternative carrier gases for GC, such as nitrogen and hydrogen. As well as lower price and unlimited availability, hydrogen has a number of potential advantages over helium, ...

  • Analysis of Multi-Pesticide Residues in Vegetables, Food, and Fruits by SPE/GC-MS

    Cleanup of matrices is the first, the most important, and the most critical step for both broad-spectrum screening and accurate determination of pesticides and their metabolites in vegetables,meats, drinks and fruits. In most cases, solid phase extraction (SPE) methods are used to clean up the extracts before the GC-MS analysis. The ideal SPE material(s) should remove the greatest number of food ...

  • Analysis of PCBs and Organochlorinated pesticides in river water using simultaneous Scan/MRM measurement in GC-MS/MS

    PCBs and some chlorinated pesticides are resistant to decomposition in the environment, and tend to accumulate in living organisms. As a result, they are designated as POPs (Persistent Organic Pollutants) under the Stockholm Convention. In monitoring these environmental pollutants in river water and sludge, sensitivity for the detection of trace quantities and separation from impurities in the ...

  • Comprehensive analysis of tobacco smoke using TD–GC×GC–TOF MS with Tandem Ionisation

    The hazardous constituents of cigarette smoke have attracted considerable attention lately, especially with increasing regulation around the world limiting or banning smoking in public places – and even in private cars if children are present. From an analytical perspective, however, there is much that remains to be learnt about the composition of cigarette smoke, because of its high degree ...
