Quantitech Ltd - suppliers of the InfraCal portable TOG/TPH
analyser - have reported high levels of interest in the device
for contaminated land investigations, following revised advice
from the UK Environment Agency.

The Qualification Requirements for Chemical
Test Data on Contaminated Soils under Policy Number: 307_03,
state -
‘The use of in-situ testing to complement MCERTS laboratory
analysis can significantly improve the quality of site
investigation and can reduce the cost of both site investigation
and remediation. It can be used for improved targeting
of conventional sampling, better spatial delineation of
contaminated areas and the development of conceptual site
models. |
'Although only MCERTS accredited data can be used to support
regulatory decisions, the Environment Agency recognises that
in-situ testing has an important supporting role to play.’
Quantitech’s Chris Tyrrell believes that the InfraCal is proving
popular for contaminated land investigations because it is
able to provide accurate measurement of petroleum hydrocarbons
at a relatively low cost.
“As a result” - he says - “Measurements can be obtained quickly
in the field (10 minutes), without having to wait for laboratory
analysis. The InfraCal range of instruments are able to measure
oil and grease in water, sludge or solids (0.5 to 5000 ppm
in water and 3 to 5000 ppm in soil) and, at only 2kg, they
are ideal for portable applications.”
