The following basic instrument calibration and verification rules are critical steps to laboratory health and safety.

1. It is important to follow the instrument manufacturer ‘s guidelines for proper calibration and verification.

No job, including instrument calibration/verification, can be performed properly or safely without the right tools. The type and concentration of calibration/verification gas (reference material), sample tubing, flow regulators, and calibration adapters are key links in the calibration chain. DCG provides the reference material and the ancillary items needed to ensure proper calibration and verification of your instruments.

2. Use only certified calibration gas before its expiration date.

The most important tool used in calibration is the gas itself. The instrument can only be as accurate as the gas used to calibrate it. DCG Provides you with a traceable Certificate of Concentration of Analytes for every calibration gas cylinder we manufacture. The concentration of calibration gas/reference material, particularly the concentration of reactive gases such as hydrogen sulfide or chlorine, will remain stable only for a finite period of time. Contact our team to assist you if your calibration/verification material has expired.

3. Train workers on the proper methods of calibration/verification.

Most instruments are designed to be calibrated with instructions detailed in Industry Methods (ISO, GPA, UOP, ASTM), user manuals, training videos, and/or computer-based training modules. Everyone responsible for performing instrument calibration should be trained and tested accordingly. DCG provides the Advanced School of Chromatography to assist our customers with training their team members and offers Intra-laboratory Studies to verify that each of the customers team members are working safely and efficiently.
