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.
Translate your method into a workable gas specification. CAC Gas can help with standard and custom references, small-volume cylinder options and gas delivery systems for experimental and analytical work.
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.
Gas chromatography & supply
Carrier-gas options, specialised regulators and laboratory gas generation.
Experimental gas mixtures
Mixing and dilution equipment for changing concentrations and controlled laboratory gas supply.
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 |
|---|---|---|
| Specialty gas references | Analytical calibration and experiments | Define composition, purity and certificate requirements. |
| Lecture bottles and cylinder options | Small-volume research supply | Confirm gas availability, valve and appropriate handling equipment. |
| Laboratory gas generators | Hydrogen, nitrogen and zero-air requirements | Match purity, flow and pressure to the instrument. |
| Gas mixers and diluters | Multiple concentrations from source gases | Specify component compatibility and concentration range. |
Ask about traceable, certified and accredited reference options where required. Accreditation and certificate scope apply to the selected product and producer.

For isotope work, specify the isotope ratio or delta value as well as the chemical composition. Stable isotope reference gases and isotopically labelled compounds are different requirements; tell CAC Gas which your method needs.
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 CAC Gas supply a small quantity for a research project?
Discuss the gas, concentration, quantity and required purity. CAC Gas can confirm suitable cylinder formats, including lecture-bottle options where appropriate.
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.
