July 2014 GC & GC–MS Environmental Food Testing and Agriculture Forensics and Drug Testing Food Safety Best Practice for Identifying Leaks in GC and GC–MS Systems Agilent Technologies, Inc. Maintaining a leak-free GC or GC–MS system is critical for obtaining optimal system performance with reliable, reproducible, and accurate results. The symptoms typically observed from leaks are presented, along with a discussion of key areas of focus to identify leaks and how to correct them. Read More Proof of Long-term, Leak-Free Performance for a Novel Self-Tightening GC Column Nut Ken Lynam, Agilent Technologies, Inc. Self-tightening nuts for GC columns maintain a leak-free seal after more than 300 injections. Standard column nuts using the same type of ferrule require retightening within just a few injections. Other advantages discussed include the easy removal of the ferrules when using this type of column nut. Read More Endrin and DDT Breakdown Using an Agilent Inert Flow Path Solution Peter Heijnsdijk, Agilent Technologies, Inc. Flow path inertness plays a critical role in pesticides analysis for accuracy and precision, especially for analytes subject to degradation in a hot inlet such as endrin and DDT. The results indicate that the Agilent Inert Flow Path solution provides superior inertness and lower breakdown than standard flow path split/splitless inlets. Read More Evaluating Inert Flow Path Components and Entire Flow Path for GC–MS–MS Pesticide Analysis Limian Zhao, Agilent Technologies, Inc. Flow path inertness is critical in pesticide analysis accuracy and precision, especially for active analytes such as organophosphate pesticides. Agilent’s Inert Flow Path, including Ultra Inert columns, liners and gold seals, and inert split/spiltless inlet, provides excellent surface inertness through the entire flow path. Read More Inert Flow Path Enhancements Improve Drugs of Abuse Testing Ken Lynam, Agilent Technologies, Inc. An evaluation of Siltite versus Agilent UltiMetal Plus Flexible Metal ferrules installed in an Agilent Ultimate Union showed improved benzodiazepine peak shape and response. Examples of forensic and toxicology check-out mix chromatograms and overlays are shown. Read More Determination of Multi-Pesticide Residues in Red Chili Powder Using QuEChERS and the Agilent 7000 Series Triple Quadrupole GC–MS System TUV-SUD South Asia Ptv. Ltd., and Agilent Technologies, Inc. Analysis of agrochemical residues in red chili is always considered difficult because of its pigments. Cleaned red chili extract was analyzed by GC–MS–MS in MRM mode by an Agilent 7890 GC with an Agilent 7000 Triple Quadrupole GC–MS system, using purged union and guard column connections. Read More   Go to Application Note Library Subscribe to the Application Note Alert LCE Print Edition LCE Digital Edition
