Agilent 3000 Micro GC configured with two performance-enhanced modules provides a fast and accurate solution for landfill gas component analysis. The individual components are baseline separated in less than 30 seconds by a two-channel configured Micro GC. With this solution, landfill gas can be monitored and controlled easily.

This document describes two methods for analyzing glyphosate, one is pre-column derivatization and the other is post-column oxidation.

This document introduces the method for determining As in samples containing high concentration of chloride using Agilent 4500 ICP-MS.

Optimized analysis of gasoline (BTEX) in water and soil using GC/FID with purge and trap

This is an application note about improving data quality in the automated HPLC analysis of PNAs (PAHs)

This application note discusses the uses of the FPD in gas chromatography, demonstrates the linearity and method detection limits (MDL) of the 6890 Series GC with an FPD, and gives examples of analyses of organophosphorus pesticides using the 6890 GC with an FPD.

This article describes a method for analyzing 1,2-ethylene dibromide (EDB) and 1,2-dibromo-3-chloropropane (DBCP) in water using the Agilent 6890 series gas chromatograph and Agilent 6890 micro-electron capture detector. The method follows EPA Method 504, using microextraction to extract the analytes from the sample, and then analyzing the extract by dual-column gas chromatography with dual micro-electron capture detectors (Agilent 6890 micro-ECDs). The micro-ECD provides significantly better stability, sensitivity, and linearity than the classical ECD. The relative standard deviation (% RSD) for the entire method is less than 7% over a concentration range greater than two orders of magnitude, with method detection limits of 0.003 mmmmg/L or lower.

This document describes the HPLC analysis method of bendiocarb and metabolite

This document describes the application of Agilent 6890 series Micro-ECD in the detection of organochlorine pesticides in various matrices in the environment and validates its performance in linear working range, sensitivity, stability and resistance to contamination.

This paper introduces a method for analyzing dioxins using Agilent benchtop mass spectrometers, which has high sensitivity and cost-effectiveness.

This Application Brief describes a method for sampling formaldehyde and acetaldehyde in air using a DNPH-impregnated silica gel cartridge and analyzing them by HPLC. The method has a limit of detection of 0.25 μg/m3 and 0.35 μg/m3.

This document describes a method for determining 61 volatile organic compounds (VOCs) using gas chromatography-mass spectrometry (GC-MS). The method uses a purge and trap (P&T) concentrator, a gas chromatograph (GC), and a mass spectrometer (MS), and does not require the use of cryofocusing. Tables 1 and 2 list the P&T and GC-MS conditions, which detail the instrument settings. The method development for analyzing 524.2 analytes was refined by members of the GC-MS Volatile Organics Analysis (VOA) group at Quanterra in Tampa, Florida.

The document is an application introduction, mainly describing the features and characteristics of the product.
