On site analysis saves on petrol

A NEW portable soil analysis kit for on-site determination of total petroleum hydrocarbon (TPH) content has been launched by manufacturer Azur Environmental.

The Remedi AID test kit was developed with Shell Research and can measure TPH across a wide range of soil types and petroleum products. Calibration allows amounts of specific petroleum products such as BTEX, PAH and leaded and unleaded gasoline to be

measured and results have shown good correlation with the standard infrared method. Azur claims that this makes the

system more flexible than existing portable systems.

Designed so there is minimal contact of the operator with contaminants, the system can run 10 tests at once and up to 25 an hour. This, it is claimed, enables a more comprehensive survey of the site because more samples can be analysed and processed than normal.

The system provides a quicker alternative to the standard laboratory method because contaminated samples only need to be sent to the laboratory for confirming contaminant content. Azur claims decisions can be taken during site investigation rather than waiting for results to come back from the laboratory.
