This document describes the separation method of Vitamin B6 complex on Pursuit Diphenyl column. The mobile phase consists of 5 mM ammonium formate and CH3CN in a ratio of 95:5. The flow rate is 0.5 mL/min and detection is performed at 254 nm. This method is suitable for the separation and detection of pyridoxamine, pyridoxal, and pyridoxine.

This is an application note about ß-Blockers Application 2326 LC technology

Fatty Acids Application 2328 LC uses HPLC technology to analyze Pursuit™ 5µ C8, 150 x 4.6mm column and uses MeCN + 0.1% HCOOH and Water + 0.1% HCOOH as mobile phase, flow rate is 1.5 mL/min, detection wavelength is 205 nm, peaks are linolenic acid, linoleic acid and oleic acid.

The document provides basic knowledge about glucuronidation, including the enzyme family, gene differentiation, and substrates. Understanding UGTs and their substrates is becoming increasingly important from an epidemiological and pharmacological perspective.

This paper introduces a method for detecting low levels of tylosin using a 320-MS triple quadrupole mass spectrometer. This method can accurately detect and quantify tylosin over a wide concentration range and below EU required tolerance limits.

This document introduces Varian's solutions in biodiesel analysis, including the full range of Varian Select™ Biodiesel GC columns, as well as automatic liquid and headspace samplers, Galaxie™ chromatography software, and optimized consumables.

This paper studies three methods of injecting chemical matrix modifiers in graphite furnace atomic absorption spectroscopy.

This paper reviews the latest advances in axially viewed simultaneous ICP-OES for elemental analysis, including improvements in detector design, software, and sample introduction systems.

This application note describes how to use Agilent PLgel MIXED-B columns to analyze reacetylated polyvinyl alcohol (PVAc).

This application note introduces EPA Method 525.2 for the analysis of semi-volatile organic compounds in drinking water and provides results for the analysis of 25 regulated compounds using the 240-MS GC/MS system.

This note details the GC analysis of a 37-component FAME mixture using the Agilent J&W CP-Select for FAME column. The column is highly selective and durable, making it suitable for FAME identification purposes.

This application note describes a multi-residue method for the analysis of PAHs, PCBs, and OCPs. These compounds have different origins and structures. PAHs contain two or more aromatic rings, PCBs contain two phenyl groups with varying numbers of chlorine atoms, and OCPs are pesticides consisting of carbon, hydrogen, and chlorine. The article also discusses the characteristics and accumulation of these compounds in the environment.

This document describes the method of using GC/MS/MS technology to detect gasoline in fire debris. The type of hydrocarbon distillate in the fire debris was determined by comparing the sample chromatogram to the standard chromatogram. In order to overcome the interference of pyrolysis products and improve the detection level, MS/MS was used as the detection method.

describes a method for the determination of chlorophenols in drinking water using GC/MS/MS
