Gluten Analysis by RPC-MALS Gluten consists of similar but distinct proteins. Molar masses and rms radii are determined by adding multi-angle light scattering to reverse-phase chromatography. Separation of Naproxen Using CHIRALPAK® IH / IH-3 CHIRALPAK AS-H and CHIRALPAK IH were used in an optimized HPLC method to separate naproxen, focusing on selectivity, resolution, and productivity in a preparative method. Doubling Chromatographic Throughput Using Dual LC The Thermo Scientific Vanquish Duo system for Dual LC enables two sample runs concurrently, so samples to run in half the time, improving pharmaceutical drug analysis. Analysis of Pesticide Residues in Grapes In this study, an LC–MS/MS method for multiresidue pesticides analysis is applied for accurate detection and quantification. Analysis of Fentanyl in Human Urine by LC–MS/MS A simple dilute-and-shoot method that provides a 3.5-min analysis of fentanyl and related compounds in human urine by LC–MS/MS using a Raptor Biphenyl column. Agilent Single Quadrupole Walkup for Multi-User Labs This App Note discusses the 6120B Single Quadrupole Walkup system, and its practical use for applications including the analysis of chemical libraries.   Sample Prep Mass-directed Purification of Piperine from Piper Nigrum Extract of black pepper was subjected to centrifugal partition centrifugation and fractions collected based on mass spectra. Determination of Patulin in Apple Juice Patulin is a naturally occurring mycotoxin produced by several species of fungi. The following method utilizes a SPE approach coupled with UHPLC–MS/MS for apple juice. Quantitation of Residual Solvents in Food Packaging by Automated Headspace–Trap GC–MS Headspace samples acquired on the Centri automated multi-mode sampling and concentration system for GC–MS can be used to screen food packaging for residual solvents.   GC Using High Performance GC–TOF-MS to Effectively Monitor Patient Opioids and Other Drug Classes The speed, resolution, and robustness of the Pegasus® BT GC-TOFMS was used to increase complex sample throughput and provide confidence in drug analysis results.   General IDP Scroll Pump Evaluation on MS This application note compares the Agilent IDP-10 Dry Scroll Vacuum Pump and Oil Roughing Pump on the Agilent Intuvo coupled to the 7010B Triple Quad MS. History of Pesticides and Pesticide Solubility Chemical pesticides are an integral part of the world’s agricultural arsenal. Because of this, pesticide residue analysis is a serious testing process in laboratories.
