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 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.

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 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 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 novel delivery molecule for a clandestine PDE-5 inhibitor drug in a dietary supplement.

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.

EtG is a minor metabolite of ethanol, can be detected in blood for up to 36 hours and in urine for up to 5 days, can be used as a biomarker for alcohol consumption. This application note describes a fast and sensitive EtG analysis method using the Varian Pursuit C18 HPLC column and 320-MS LC/MS/MS system, which demonstrates good linearity, high sensitivity, and stable ion ratios with a detection limit of 10 ppb.

This document introduces a technique for analyzing zinc-based alloys using atomic absorption spectrophotometry. The technique can be used to measure zinc, aluminum, copper, iron, lead, and tin.

The application note describes the methods employed at Agilent Technologies in the analysis of iron ore samples for fifteen different elements.

This document introduces a method for quantifying multi-class pharmaceuticals in water using simultaneous positive and negative ESI on the Varian 320-MS triple quadrupole mass spectrometer

This application note describes the application of microimaging techniques in industrial applications, with an emphasis on the case study of using MRI to study the curing process of plaster cement.
