Laboratory Services


While each CEM staff member has a particular expertise, the entire group operates as a team to provide clients with regulatory information and comprehensive analytical services that include:

  • Atomic emission spectroscopy by inductively coupled plasma for metals analysis.
  • Gas chromatography with multiple detectors for organics analysis.
  • Ion chromatography for acids and hexavalent chromium analysis.
  • Gravimetry for particulate and oil mist particulate analysis.
  • Phase contrast microscopy for fiber count and particulate measurement.
  • UV/VIS spectrometry for colorimetric and ultraviolet analysis.
  • Specific ion electrodes for anions and cations.
  • Infra-red (IR) spectrometry for oil mist and silica analysis.


CEM’s service standards include:

  • Guaranteed five-day turnaround (same-day and second-day rush services are available).
  • Toll-free, technical support hotline: 1-800-252-2236.
  • Laboratory staff who are degreed professionals.
  • Customized data reporting, either fax or computerized data transfer backed up with hard copies.
  • The S3 Program–Our trademarked Sampling, Simulation and Savings Program that establishes frequency, quantity and sample combinations. The program may also be used for pro-active control by “simulating” new chemicals in the workplace and predicting exposure levels prior to actual introduction. This program regularly achieves annual sampling cost savings of 40-50%.
  • Third generation instrumentation.
  • Customized data collection sheets.

The Laboratory Services Division of CEM provides support every step of the way, from initial sampling strategies to final reporting of results and recommendations.


Quality assurance is paramount and CEM’s monitoring meets or exceeds all mandated guidelines. The chromatography and spectroscopy laboratories run quality control samples consisting of blanks, duplicate analyses, spiked analyses, and independent standard verification samples. Our microscopy laboratory quality checks 20% of all samples, double the industry rate. For chemical analysis, accuracy and precision data are generated from two (2) laboratory control samples (LCS), where possible. The first LCS is analyzed as a media/method spike and the second is analyzed and compared to the first as a media/method duplicate.
