QA samples (Blanks, Duplicate & Spikes)
1 The TestAmerica laboratory performs an isotope dilution methodology which employs internal standards which are stable isotopically labeled analogs of the target analytes added to the sample prior to
extraction. Physical and chemical properties of each labeled compound are virtually the same as its unlabeled native analog, thus any losses of the target compound that may occur during sample preparation or
determinative steps will be mirrored by a simlar loss of the labeled standard. A recovery correction is then applied to sample results.
2 Except where noted the associated MB, low-level LCS, mid -level LCS/LCSD and MS recoveries were in control for TestAmerica data. QC data not yet reported for EPA.
3 The internal standard/surrogate is added to samples prior to the extraction step.
4 The TestAmerica low-level LCS associated with this batch of samples exhibited a percent recovery above the QC control limits. This is an indicator that data may be biased high. This outage is due to a miss spike
by the laboratory. The mid -level LCS was in control; therefore, corrective action was deemed unnecessary.
