QuEChERS Method for Pesticide Residue Analysis
QuEChERS method for pesticide residue analysis requires only small quantities of solvent and is capable of generating recoveries of 70-120% with RSDs <5% for a wide range of compounds.
Fast Extraction and Low Level Detection of Chloramphenicol in Shrimp
A highly selective and sensitive analytical method was developed for chloramphenicol using a QuEChERS type sample preparation approach and LC-MS/MS detection.
Reduce Matrix Background and Improve Overall Analyte Recovery for the Analysis of Pesticides in Beef Kidney
Supel QuE Z-Sep+ was successfully demonstrated for cleanup of beef kidney matrix, providing reduced background and less interference in the GC-MS analysis of the target pesticides
LC/MS/MS Analysis of Pesticide Residues in Pistachios on the Ascentis® Express RP-Amide Column after QuEChERS Extraction
LC/MS/MS Analysis of Pesticide Residues in Pistachios on the Ascentis® Express RP-Amide Column after QuEChERS Extraction
Banned and Other Neonicotinoids from Plant Material
On Friday, April 27, 2018, the European Union decided to ban the use of three neonicotinoid insecticides from use on field crops, having deemed them dangerous to bees. This application demonstrates the analysis of these banned compounds and others from
Increase Removal of Fat and Pigment from Avocado Extracts Prior to GC-MS Analysis of Pesticide and Metabolite Residues
Supelco's Z-Sep+ sorbent effectively removes fat and pigment interferences from avocado, with good pesticide recoveries; it removes more matrix than traditional PSA/C18 sorbent, and produces a lower background for GC-MS analysis.
Extraction and Analysis of PAHs from Grilled Hamburger
A QuEChERS approach was effectively used to extract PAHs from grilled hamburger meat; the SPB-608 GC column provided the selectivity necessary to resolve all but one isomeric set.
