Overview

A wide range of on site instruments are available on the market for the detection and quantification of many of the gas components found on and near contaminated land and landfill sites. Serious site investigations should also require periodic verification of on site readings together with quantitative analysis of minor gas components and investigation of the origin of some of the bulk gasses, most commonly methane. This analysis is laboratory based and involves a variety of techniques from Gas Chromatography to Mass Spectrometry.

Gresham Gas Sampling Equipment

Gresham Gas Sampling Equipment is generally accepted as the most reliable and cost effective method of taking a gas sample for laboratory analysis from landfills, mines, flue discharges and a whole range of other sources.

Easy To Use

The popularity of the Gresham Gas sampling system is due to the ease with which a sample can be taken at the site and the convenience of transporting it to the laboratory for analysis. A sampling kit weighing only 5 kg and requiring no electrical supply is widely used for most applications. The compressed sample can be introduced from the cylinder into the analyser via a dosing valve or septum allowing a comprehensive analysis to be carried out from a single sample.

Specifications

The cylinders used are extremely durable and are available in aluminium alloy and stainless steel. At the recommended pressure of 14 Bar the most popular 55ml cylinder will contain nearly 0.75l of sample gas at atmospheric pressure.

Relocation

Based in Surrey for the last 40 years we have recently relocated from Woking to new facilities in Camberley and are now part of the Fox VPS Ltd group of companies.
