The document introduces the operating parameters selection method of a new boosted discharge bismuth lamp developed by Agilent. This lamp has higher intensity and less curved calibration graphs than conventional bismuth hollow cathode lamp.

This application note describes a novel delivery molecule for a clandestine PDE-5 inhibitor drug in a dietary supplement.

This application note describes how to analyze bumetanide in a dietary supplement using the Varian 500-MS Ion Trap Mass Spectrometer in positive and negative ionization mode.

This application note describes a method for the analysis of perchlorate using the Varian 1200L triple quadrupole mass spectrometer. The method has high selectivity and sensitivity and can be used to analyze perchlorate in contaminated water sources.

This document describes the method of using the Varian 500-MS ion trap mass spectrometer in TurboDDS™ mode to test male enhancement supplements for adulteration with clandestine PDE-5 inhibitors (ED drugs like Viagra®, Cialis® and Levitra®).

This application note describes the use of the Varian 320-MS Triple Quadrupole LC/MS/MS for the analysis of 15 azo dyes. This method provides high sensitivity, accuracy and selectivity, making it a useful tool for regulatory monitoring and quality assessment.

A fast and accurate method for the determination of controlled dyes in textiles is described. The method is based on LC/MS/MS combined with MRM using a triple quadrupole mass spectrometer equipped with an electrospray ionization (ESI) source.

This document describes the application of Varian's LC/MS/MS technology in the determination of 80 pesticides in vegetables. The analysis can be performed with high accuracy, sensitivity, and speed using Varian's 320-MS Triple Quadrupole Mass Spectrometer and Polaris 3µm C18-A column.

This application note describes a method for the direct aqueous injection and automated on-line solid phase extraction (SPE) analysis of phenoxy herbicides in drinking water using the Varian 320-MS triple quadrupole LC/MS/MS. The method provides high sensitivity, selectivity, and analysis speed, meeting the requirements for trace-level quantitation of phenoxy herbicides in drinking water.

This application note describes a graphite tube design that addresses these limitations--with improved sensitivities and detection limits compared to previous tube designs

This document describes a simple, high-throughput LC/MS/MS method for the detection and quantitation of (±)-11-nor-9-carboxy-delta-9-THC in urine using negative ion electrospray. The method does not require derivatization and provides the same specificity and sensitivity as GC/MS.

This document provides information on the source, structure, hazards, and testing methods of mycotoxins in food and feed. Mycotoxins are secondary metabolites of molds that contaminate crops and fruits, posing health risks to humans. The formation of mycotoxins is weather-dependent, making prevention challenging. More than 25% of global agricultural production is contaminated with mycotoxins, resulting in significant economic losses. Many countries have implemented regulations to limit mycotoxin exposure, impacting food and animal feed trade. Testing of raw materials and products is necessary to ensure the safety of food and feed. Current testing methods include gas chromatography with electron capture detection and gas chromatography-mass spectrometry.

This application note describes a new EPA drinking water LC/MS/MS method for the determination of non-volatile compounds on the Varian 325-MS triple quadrupole mass spectrometer.
