Stack & combustion emissions
Zero and span references for continuous emissions analysers and combustion testing.
CAC Gas & Instrumentation
Environmental
Reference gases for meaningful emissions data.
Calibration standards and gas delivery solutions for stack emissions, ambient air, biogas, landfill and environmental laboratories.
Defined gas specifications
Composition selected for your instrument and method.
Compatible delivery equipment
Cylinders, regulators and gas control for the application.
Application support
Discuss your requirements with the CAC Gas team.
Overview
Start with the measurement you need.
Give your monitoring program a clearly defined reference. CAC Gas supplies gas standards and supporting equipment for environmental measurements, with compositions and certification selected for the analytical method.
Tell us the instrument, gas specification and expected usage. Our team can help identify a suitable reference and gas delivery arrangement for your application.
Applications
Match the reference to the task.
Choose the mixture, concentration and delivery conditions for the specific detector, analyser or method.
Ambient air & VOC analysis
Reference mixtures for air quality measurements and laboratory methods for volatile organic compounds.
Biogas, landfill & carbon capture
Standards for methane, carbon dioxide and other components relevant to the monitoring system.
Gas & supply options
Define your gas specification.
These examples are a starting point for an enquiry. Exact composition, certification, packaging and current availability are confirmed for the selected product.
| Reference or supply option | Typical measurement task | What to specify |
|---|---|---|
| CEMS gas standards | Stack analyser calibration | Specify the analyser range and required certification. |
| VOC and TO mixtures | Ambient air, soil and water analytical methods | Request the method-specific component list. |
| CH4 / CO2 / O2 mixtures | Landfill and biogas analyser testing | Select concentrations to cover the expected measurement range. |
| CO2 reference mixtures | Carbon capture and greenhouse gas measurement | Define concentration, balance gas and uncertainty. |
Ask about traceable, certified and accredited reference options where required. Accreditation and certificate scope apply to the selected product and producer.

Ask for EPA Protocol or accredited options where the measurement method calls for them. Specify the exact method and certification rather than assuming one type of certificate suits every environmental application.
Include your delivery location and required date so cylinder selection, expected use and supply arrangements can be discussed together.
Common questions
Before you specify a gas.
Can one cylinder provide several calibration points?
A compatible mixer or diluter can create multiple concentrations from a source gas. CAC Gas can assess the required range, flow and gas compatibility for your method.
Can I request a custom gas mixture?
Send the required components, concentrations, balance gas and uncertainty or certification requirements. CAC Gas will confirm mixture feasibility, cylinder options, shelf life and lead time with your quotation.
What should I include in my enquiry?
Include the instrument make and model, analytical or test procedure, gas specification, usage, cylinder connection and flow requirements. Add the delivery location and required date so the team can prepare a suitable quotation.
