MACHEREY-NAGEL 730223 CHROMABOND Polypropylene Centrifuge Tube with Screw Cap for Quenchers, 50 ml Capacity (Pack of 50)

Special products for determination of pesticides in food samples. Quenchers method and pre-mixes. Within a few years after its development by Anastasias et al. the Quenchers method has gained a leading position for the determination of pesticide residues in food samples by GC-MS or LC-MS, allowing rapid and cheap clean-up of strongly matrix-contaminated samples. For optimizing the extraction of pH-dependent compounds, for minimizing decomposition of sensitive substances, and for broadening the matrix spectrum, different modifications of the Quenchers method have been elaborated. MACHEREY-NAGEL offers a number of individually weighed and premixed extraction (buffered or non-buffered) and clean-up mixtures, specially composed for different sample matrices.

• Special SPE phase for quick and cheap determination of pesticides in strongly matrix-contaminated samples by GC-MS and LC-MS
• Quenchers method = Quick Easy Cheap Effective Rugged Safe
• Different sizes (e. g. , 2 mL, 15 mL centrifuge tubes), aluminum bags
• For clean-up, the Diamine phase (PSA) removes, polar compounds e. g. , sugars and organic acids
