Understanding your Laboratory results
QROS is proposing to host some small seminars aimed at enabling you to get the most out of your laboratory result. It will focus on understanding what your reports tell you and what they don’t tell you, and how to get the relevant information to attain more information from it.
The seminars will also cover how best to compare site and lab data.
If you are interested in attending this free event please send your details using the form below.
Your details will be kept confidential and not shared with any other organization.

On-
QROS utilize a number of analytical techniques depending on the contaminant under investigation and/or the limits of detection required. For the most part we investigate hydrocarbon and heavy metal contaminants and both these normally use fluorescence as a method of detection, either in the ultraviolet (UV) spectrum for hydrocarbons or in the X ray spectrum for heavy metals. Both these techniques have been utilised in labs for some years but have only recently been become reliably available as hand held portable instruments for field use.
Other analytical techniques techniques employed rely on spectrophotometric determination for a range of different contaminants, Anodic stripping voltammetry (ASV) for Heavy metals at ppb levels and traditional potentiometric sensors probes for pH.
QROS are also currently working on a novel heated diode system for quantitative analysis of HVOC’s
Use the links above to find out more information each technique or contaminant type.
