Contaminated Land – Why use ION Science PID?

Apr 11 2023

Portable photoionisation detectors (PIDs) have become an important tool in the management of many contaminated land remediation projects, this guide explains why the ION Science Tiger XT is best suited for the job!

Tiger XT have been designed specifically for challenging field conditions. These rugged instruments benefit from the advanced features of the MiniPID 2 sensors, such as detection limits down to 1 ppb, and measurement ranges up to 20,000 ppm. Crucially however, the Tiger XT range is unaffected by the problems that plague other PID instruments. This is because a unique design eliminates any potential effects of varying humidity and contamination.

In addition to the health risks posed by VOCs, their accumulation in contaminated land can represent an explosion risk, so the ION Science portable PIDS benefit from global Intrinsic Safety (IS) certification for use in potentially explosive atmospheres.

The Tiger XT is supplied as standard with a 10.6 eV lamp for the measurement of a wide range of VOCs. However, benzene is a particularly toxic VOC, and some site conditions set specific targets for this compound. Importantly, the new Tiger XT Select (XTS) utilises the ION Science 10.0 eV lamp to detect Total Aromatic Compounds (TACs) such as benzene, toluene and xylene, and is supplied with a pack of pre-filter tubes for the specific, selective detection of benzene. This speciation capability for benzene is a major advantage, given the complexity and cost of alternative benzene-specific measurement techniques.
