This application note will discuss system optimization for the analysis of polar oxygenate additives in drinking and ground waters using Agilent GC coupled to MS

Agilent 7500c ICP-MS can meet the regulatory requirements for trace metals in drinking water around the world. Elements previously relegated to other techniques, such as GFAA or ICP-OES due to very high or low concentrations or the presence of interferences, can now be measured in a single analysis.

This document introduces the HPLC analysis of six different antibacterial drugs, including nalidixic acid, trimethoprim, sulfamethoxazole, chloramphenicol and furazolidone. The SB-C18 column provides excellent peak shape and selectivity for basic antibacterial drugs at low pH. The method is easy to use, reliable and accurate.

This application note describes a method for the qualitative and quantitative analysis of explosives and related compounds using Agilent's ZORBAX®SB-C18 and SB-CN columns. The method combines the excellent separation capabilities of the polar and nonpolar columns and has been proven to perform well in a variety of applications.

This document describes a method for separating carbazole and its metabolites using the Agilent ZORBAX 300 SB-C18 column at low pH. The method achieves resolution of peaks 1 and 2 that was not previously possible, and provides stable and reproducible chromatography at pH < 1.

This document introduces a method for separating explosives from soil extracts using an Agilent ZORBAX SB-C18 column. The method uses methanol-water (50:50) as the mobile phase and a detection wavelength of 230 nm.

Analysis of Rare Earth Elements in Geological Samples by Laser Ablation - Inductively Coupled Plasma Mass Spectrometry (LA-ICP-MS)

The document describes a method for high-resolution separation of sulfonylurea pesticides, highlighting the excellent selectivity and peak shape of a new family of pesticides. ZORBAX SB-C18, a sterically protected, bonded phase, is used for reliable results run-after-run. The document provides the separation conditions and sample preparation method for various sulfonylurea pesticides.

This document mainly introduces the method of using solid-phase extraction and gas chromatography-mass spectrometry to analyze phenols in water.

A liquid chromatography/mass spectrometry method using an electrospray ionization source in positive ion mode was developed for the analysis of glyphosate (N-phosphonomethyl glycine) and its metabolite, aminomethyl phosphonic acid in water. Both glyphosate and its metabolite were derivatized using 9-fluorenyl-methyl chloroformate in buffer solution prior to reversed phase high performance liquid chromatography separation. The method cleanly resolved both target molecules with excellent sensitivity in both positive and negative ion modes.

This Application Note describes the use of Agilent Purge-and-Trap/Gas Chromatography/Mass Spectral Detection technology for the analysis of volatile organic compounds in water.

This paper summarizes the standard method for tuning 4-bromofluorobenzene (BFB) and introduces three methods for tuning Agilent 6890/5973 GC/MSD systems.

This article describes a liquid chromatography/mass spectrometry method that has been successfully applied to the sensitive and simultaneous determination of the pesticides Simazine, Thiobencarb, and Thiuram. The method is selective and sensitive, making it suitable for the determination of these pesticides in drinking water.

This application describes methods for the analysis of a variety of phenols using an Agilent 6890 Plus GC system and 5973N MS detector with high resolution and fast quantitative methods. The provided analysis methods are useful for definitive assignment of the identity of phenols present in the analysis samples and for quantitative analysis of phenols.
