Standard Practice for Screening Trichloroethylene (TCE)-Contaminated Media Using a Heated Diode Sensor (Withdrawn 2022)
The following bibliographic material is provided to assist you with your purchasing decision:
Scope
1.1 This test method describes a procedure for screening soil known to contain the halogenated volatile organic compound (HVOC), trichloroethylene (TCE), by measuring the TCE concentration in the headspace above a sample of the soil using a heated diode sensor device. From this measurement, an estimated concentration of TCE in the soil can be determined. Any TCE remaining in the soil sample is not measured by this test method. Any other HVOC present in the soil will be reported as TCE.
1.2 This test method can also be used for screening the headspace above a soil suspected of containing HVOC contamination to indicate the presence or absence of HVOC contamination in the soil. Any HVOC contamination remaining in the soil is not detected by this test method.
This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the application of regulatory limitations prior to use.
Note 1The diode sensor is heated to temperatures ranging between approximately 600 and 1000 C (see ) and as a result could be a source of ignition.
