Calibration

Laboratory analysers and process instrumentation require frequent calibration with high precision specialty gases mixtures.

Gas detection systems

For safety in industries such as the petrochemical processing industry, the use of gas detection systems is common. These systems sniff for flammable and toxic gases in the air and trigger an alarm when dangerous conditions are encountered. Gas detection systems require frequent functionality testing with calibration gas mixtures. They also require calibration at regular intervals with accredited reference materials, a high quality type of calibration gas mixture.

Laboratory analysers

The sophisticated equipment used in laboratories for forensic science, biotechnology research and petrochemical quality assurance all require diverse ranges of calibration mixtures.

Process instrumentation

To ensure that chemicals processes, combustion operations and refining operations are optimised, it is important to measure and control process parameters using process instrumentation. These instruments require periodic calibration with certified calibration gas mixtures.

Emissions monitoring

Gas emissions from cars, trucks and factory stacks contain pollutant chemicals such as nitric oxide and carbon monoxide. These must all be measured with high accuracy to ensure that our environment remains unpolluted and the air around us is healthy to breathe. The instruments used for these purposes require validation with high precision calibration gas mixtures at frequent intervals to ensure compliance with local legislation.

Calibration Gases and Gas Mixtures for Accurate Measurement

Calibration gases are precisely defined reference gases and gas mixtures used to test, adjust and verify gas detectors, gas analysers and similar instruments to support accurate performance. Coregas manufactures a wide range of calibration gas products, often custom-made, to suit different industries and measurement requirements.

Typical Calibration Applications

  • Gas detection systems (fixed and portable): Routine servicing and verification using suitable calibration gas mixtures.

  • Laboratory analysers: Calibration to maintain confidence in analytical measurements.

  • Process instrumentation: Span gas or test gas for process control analysers that monitor gas and liquid streams.

  • Emissions monitoring (including CEMS): Calibration mixtures to validate monitoring instrumentation used for compliance and environmental reporting.

  • Air quality monitoring: Mixtures for highly sensitive instruments measuring ambient pollutants at low concentrations.

  • Vehicle emissions and type approvals: Traceable calibration gas mixtures to support emissions testing requirements.

Portable Calibration Gas for Field Teams and Remote Sites

Where calibration work happens in the field, compact and lightweight portable cylinders are a convenient option for taking calibration gas mixtures to remote locations such as fixed gas detection systems and smokestacks. Coregas also offers a return service approach for portable cylinders, supporting simpler end-of-use handling.

Safety and Handling Essentials

  • Use the correct mixture for the instrument: Match gas composition, balance gas, concentration range, and required certification level to the analyser or detector specification.

  • Check cylinder labels and documentation: Confirm mixture details, expiry or stability period, and storage requirements before use.

  • Prevent contamination: Use the correct regulator and fittings, keep caps on when not connected, and avoid introducing moisture or particulates into sampling lines.

  • Ventilation matters: Use calibration gases in well-ventilated areas and follow site procedures for gas handling.

  • Secure cylinders: Store and use cylinders upright and restrained to prevent tipping or impact damage.

  • Follow SDS and site rules: Always align with the product SDS and your internal safety procedures.

Transport and Classification (NZ / International)

Calibration gases can vary significantly in composition, so transport requirements and hazardous classifications depend on the specific mixture and cylinder label. Always transport cylinders upright and secured in a ventilated vehicle compartment, keep valves closed and protected, and follow the SDS and any relevant carriage requirements for the product supplied.

Ordering, Delivery and Supply Options

Coregas can support delivery or collection options depending on location and product availability. For stocked gases, delivery timelines may differ from rarer gases and special mixtures.
