Tiger portable VOC detector

Industry/Application

Contaminated Land Remediation

Leading independent site investigation, geotechnical engineering and environmental consultancy Southern Testing, has opted to use handheld Tiger VOC detectors from ION Science to measure volatile organic compounds in the field.

Recommended by ION Science’s exclusive UK distributor, Shawcity Ltd, as a replacement for equipment that was no longer supported by its manufacturer, the revolutionary Tiger PID (photoionisation detection) instruments enable
Southern Testing to make an assessment of risk associated with ground-borne vapour, and also to screen soil samples, which then allows them to make the best use of their laboratory analysis budgets.

According to Dr Lawrence Mockett, Director at the Sussex-based consultancy, the ground vapour is measured in monitoring wells, while soil samples are screened by headspace, with the equipment used four or five times each week at various sites around the UK.

Dr Lawerence Mockett, Director at Southern Testing:

“We needed a cost effective VOC instrument that was accurate, repeatable and user-friendly. The ION Science Tiger, purchased from Shawcity, fitted our requirement whilst providing an affordable and reliable replacement.”

“We have been very pleased with the ION Science Tiger to date and would not hesitate to recommend it to other facilities”.
