From the integrity of the sample, to the precision of the equipment, to the accuracy of the analysis, we rigorously monitor every stage of the examination process to ensure the quality of our results.  We are approved by the U.S. EPA, NELAP, DOD, and state regulatory agencies.  In our ongoing efforts to provide the finest laboratory services available to our clients, we participate in Laboratory Performance Evaluation Studies and enlist the resources of other professionals in the field for annual third-party audits.

Data Evaluation

While all data is automatically transferred from instruments to our LIMS computer system for initial results, LIMS evaluation is only the beginning of the data validation process.

Our chemists are responsible for maintaining instruments, chemicals, and standards according to EPA protocol.  We use primarily EPA procedures for sample analysis and require our chemists to calculate the data, prepare the data for reporting, maintain all raw data and files, and, as Tier I review, check for outliers with poor spike recovery, poor precision, poor standard curve, or an imbalance among various parts of the whole.  If necessary, TraceAnalysis chemists reanalyze the sample to ensure the accuracy of the results.

Besides maintaining a record of each analysis on the LIMS computer network, we record most analyses in a bound notebook with the following information:

  • Chemist’s signature,
  • Date,
  • TraceAnalysis sample number,
  • Non-standard setup conditions,
  • Quality Control information,
  • Results.
Our Laboratory Supervisor or one of our Directors always conducts a Tier II Review of the initial results of each analysis, records any problems, notes any corrective actions taken as a consequence of the review, then dates, initials, and explains any changes in the analytical process.

Data Reporting

We report on a wet-weight (“as is”) basis.  If requested, we will also determine percent moisture for each sample and report results on a dry-weight basis.  We report percent solids to the nearest tenth percent mg/kg and routinely include batch quality control results with the data, based on the following rounding of calculations:

  • Inorganics/Metals
  • RPD: nearest whole percent
  • Percent Recovery: nearest whole percent
  • Organics
  • RPD: nearest whole percent
  • Surrogate & MS/MSD Percent Recovery: nearest whole percent
TraceAnalysis data reports are concise, complete, simple, and tailored to client requests.  At a minimum, all our reports include the following information:
  • Identification of the laboratory
  • TraceAnalysis sample ID number
  • Client sample identification
  • Date sampled
  • Date of extraction or prep
  • Date of analysis
  • Parameters measured
  • Units used for each parameter reported
  • Methods used plus annotations
  • Reporting limits
  • Limits, RL, SQL, MQL
  • Dilution factors, surrogates, data acceptability, method blanks
  • Certification signature
  • Chain-of-Custody copy
  • TRRP reports also include: MS, MSD, ICV, CCV, LCS, LCSD, LODs, MQLs, SQLs, and Check List
After compiling the completed data report, TraceAnalysis conducts a final check of the information as a Tier III Review.  One of our Directors then signs the final report and relays it to our client in the format requested.  Data is faxed or emailed in electronic format to clients.  This allows clients to download reports and tables of data directly into their own reports.  We hold samples in storage for a minimum of three weeks to allow clients a review of the data and the opportunity for reruns or additional analysis if necessary.  We also store all hard copies of the data, custody records, worksheets, and other project records in our security files for no less than five years.
