This Report of Analysis contains the analytical result(s)for the sample(s) listed on the Sample Summary
following this Case Narrative. The sample receiving date is documented in the header information
associated with each sample.
All results listed in this report relate only to the samples that are contained within this report.
Sample receipt, sample analysis, and data review have been performed in accordance with the most
current approved The NELAC Institute (TNI) standards, the Pace Analytical Services, LLC ("Pace")
Laboratory Quality Manual, standard operating procedures(SOPs), and Pace policies.Any exceptions to
the TNI standards, the Laboratory Quality Manual, SOPs or policies are qualified on the results page or
discussed below.
If you have any questions regarding this report please contact the Pace Project Manager listed on the
cover page.
In the Matrix Spike and Matrix Spike Duplicate(MS/MSD) associated with sample-001, PFDOS
recovered outside of the acceptance limits. The Laboratory Control Spike (LCS) recovered within the
required acceptance limits; therefore, this demonstrates a matrix effect and data quality is not impacted.
