Trip Spikes
A sample prepared by the laboratory that is fortified with a known concentration of target analytes. This sample is shipped along with containers and is to be taken into the field, but returned unopened to the laboratory. Analysis is conducted and recoveries are reported and expressed as a percentage.
Frequency and Purpose
Optional. 1 per VOC monitoring program.
Monitors the breakdown or loss of analytes during the sampling process. Holding time and temperature effects on target parameter concentrations can be assessed.
Application and Regulatory Criteria
Typically used for volatile organics in water, however may be applied to other analytes. Confirm availability with your supplying laboratory.
| Majority of VOCs | 60% - 130% |
| Vinyl Chloride, Bromomethane, Chloromethane, Freon-12, Acetone, MIK, MIBK | 50% - 140% |
Recommended Actions
Please note in the absence of regulatory prescribed warning or alert limits in some regions, Bureau Veritas Laboratories recommends these limits. Review storage conditions, temperatures of samples upon receipt, if an exceedence of the alert limit is reported.
