in house water testing instrumentation - RWA LabIn-House Water Testing Instrumentation

The RWA Lab is a full-service laboratory and maintains state-of-the-art instrumentation including several units that are liquid chromatography coupled with tandem mass spectrometry, gas chromatography coupled with tandem mass spectrometry, gas chromatography with mass spectrometry, inductive coupled plasma and atomic absorption.

All laboratory instrumentation is maintained following procedures outlined by the instrument manufacturers. Preventive maintenance, such as lubrication, source cleaning, and detector cleaning, is performed according to the procedures and timeline described in the manufacturer’s instrument manual. Precision and accuracy data are examined for trends and excursions beyond control limits to determine evidence of instrument malfunction.

Maintenance is performed when an instrument begins to degrade as evidenced by:

  • Degradation of peak resolution,
  • A shift in calibration curve,
  • Decreased ion sensitivity, or
  • Failure to meet our quality control criteria.
