Agilent Environmental Solutions

Significance of the Topic

Environmental monitoring of water, soil, air, and food is critical to ensure public health and ecosystem integrity. Stringent regulations worldwide demand analytical methods that deliver rapid, accurate, and reproducible data on trace organic and inorganic contaminants. Integrating sample preparation, separation, detection, and data management into a seamless workflow enhances laboratory productivity and compliance.

Objectives and Overview

This summary presents an integrated portfolio of Agilent instruments, consumables, and software designed to streamline environmental analyses. The focus is on end-to-end solutions—from sample preparation through chromatographic separation and detection to data interpretation—tailored for routine and complex applications in environmental laboratories.

Methodology and Approaches

Key components of the workflow include:

• Sample Preparation: Filtration, solid-phase extraction (SPE), and QuEChERS kits for efficient cleanup of complex matrices.
• Gas Chromatography/ Mass Spectrometry (GC/MS): High-sensitivity triple quadrupole and single quadrupole systems with advanced columns (J&W GC) for volatile and semi-volatile organics.
• Liquid Chromatography/ Mass Spectrometry (LC/MS): Workhorse and high-resolution instruments with Poroshell 120 columns for rapid, high-throughput separation of polar and emerging contaminants.
• Headspace and Thermal Desorption: Automated headspace samplers (7697A) and Markes thermal desorption units for volatiles and semi-volatiles.
• Atomic Spectroscopy: ICP-OES and ICP-MS platforms for multi-element analysis with low detection limits and wide dynamic range.
