  • 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 ...

  • Solid Phase Microextraction of Organophosphate Insecticides and Analysis by Capillary GC/MS

    SPME was used to extract an aquatic sample for analysis of organophosphate insecticides by gas chromatography/mass spectrometry (GC/MS).  An SPME fiber coated with 8.5um of polyacryate yielded detection limits ranging from 0.10 to 0.56ug/L. SPME is a quick and highly sensitive sample preparation technique that eliminates the use of solvents.         ...

  • 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 ...

  • 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 Organophosphorus Pesticides in Baby Foods Using a Triple-Quadrupole GC/MS/MS System

    Contamination of food products with pesticides is a growing concern because of recognized adverse health effects, increasing world-wide usage of pesticides, and increasing imports of raw foodstuffs from foreign sources. The concern is particularly acute for baby foods because of the high vulnerability of babies to adverse health effects from synthetic chemicals, particularly ...

  • Analysis of Pesticides in Baby Foods Using a GCMS-TQ8030 GC/MS/MS, Part II

    Contamination of food products with pesticides is a growing concern because of recognized adverse health effects, increasing world-wide usage of pesticides, and increasing imports of raw foodstuffs from foreign sources. The concern is particularly acute for baby foods because of the high vulnerability of babies to health effects from synthetic chemicals such as pesticides. Gas chromatography ...

  • 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 ...

  • 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 ...

  • airmoTWA: New Expert System for GC-FID/MS
