Keywords Pesticides, Large Volume Injection, Automated Evaporation and Concentration, Gas Chromatography-Mass Spectrometry, PTV Inlet, Cooled Injection System. Abstract Pesticides are frequently determined in various food and beverage types and in […]
LEARN MOREApp Note 210/2020 The manual preparation of calibration standards and QC samples is part of the daily activities of laboratories that analyze food samples for contaminants. The accurate and precise […]
LEARN MOREApp Note 196/2018 In the work presented here, highly sensitive determination of around 100 contaminants in surface water in the concentration range from low double digit to low triple-digit pg/L […]
LEARN MOREThis study focuses on the simultaneous detection of OP pesticides using two 8890 gas chromatographs with a GERSTEL MPS roboticpro sampler. The MPS was configured to perform liquid injection. Static […]
LEARN MOREApp Note 209/2019 The number of cannabis containing products, such as extracts, tinctures, edibles, waxes and oils, available in the United States have increased significantly due to changes in state […]
LEARN MOREApp Note 7/2010 Fruit and vegetable extracts that are produced following the well established QuEChERS method typically contain a significant amount of nonvolatile matrix material. After several injections of such […]
LEARN MOREApp Note 12/2008 A novel stir bar sorptive extraction (SBSE) procedure – “Sequential SBSE” was developed. Compared to conventional SBSE, sequential SBSE provides more uniform enrichment over the entire polarity/volatility […]
LEARN MOREApp Note 12/2006 A method for fast screening of pesticide multi-residues in aqueous samples using dual stir bar sorptive extraction (dual SBSE) – thermal desorption (TD) – fast GC/MS has […]
LEARN MOREApp Note 4/2006 In this study we describe direct liquid injection techniques compatible with “dirty” samples containing non-volatile components. Using a glass liner that can be removed and replaced after […]
