    Successful Emissions Monitoring with CAC GAS Specialty Gases

    Audra Pettett

    According to the Encyclopedia Britannica, a “greenhouse gas is any gas that has the property of absorbing infrared radiation (net heat energy) emitted from Earth’s surface and reradiating it back to Earth’s surface, thus contributing to the greenhouse effect. Carbon dioxide, methane, and water vapour are the most important greenhouse gases. To a lesser extent, surface-level ozone, nitrous oxides, and fluorinated gases also trap infrared radiation. Greenhouse gases have a profound effect on the energy budget of the Earth system despite making up only a fraction of all atmospheric gases.”

    Cylinder Options for Liquefied Gas Mixtures

    Matt Shaw

    Liquefied gas mixtures, or ‘liquid mixtures,’ are often used for calibrations where the application demands calibration with a ‘heavy’ or longer-chain hydrocarbon (see Demystifying hydrocarbon gas mixtures in non-refillable cylinders). Liquid mixtures have the advantage of closely matching the product being analysed (e.g. stream gas), while also offering increased efficiency by allowing an increased number of calibrations with the same cylinder, when compared to a gaseous mixture.

    While liquid mixtures do have significant advantages, there are some disadvantages to consider. As is described in our previous blog on Issues with liquefied calibration gases, there are rules that can be followed to mitigate the issues. One of those being choice of cylinder type.

    Calibration Gas for Nitric Oxide, Nitrogen Dioxide, and Nitrogen Oxides

    Greg Shires

    Nitric oxide (NO), nitrogen dioxide (NO2), oxides of nitrogen or nitrogen oxides (NOX) are by products of several processes including incomplete diesel combustion, power plant production & incineration, just to name a few.

    There are often questions regarding which calibration gas to use, what is the correct balance gas, and/or what regulator and tubing should be used.

    Let us get the information on these calibration gases correct.   

    Here are some recommendations to follow:

    Traceability & Certification: What's the difference?

    Paul Fry

    In the world of measurement and calibration, the most reliable way to determine a product’s quality is the evidence provided to support the claims about a product’s attributes: Traceability and Certification.

    A detailed outline of these attributes can be found in our Introduction to Calibration Gases article.

    CAC Gas has three classifications of gas and liquid mixtures in high pressure cylinders.

    How to Ensure Breathalyser Accuracy.

    Maria Pamboris

    Alcohol impaired drivers risk not only their own lives but the lives of others. They can face large fines, loss of license and even imprisonment. By removing these drivers, we reduce the potential for serious injury or fatal collisions on our roads.

    But how do we do that?

    SilcoNert® - Better performance, better results.

    Matt Shaw

    What is it?

    SilcoNert® is a non-reactive silicon coating process that makes flow paths inert for better process control, consistent sampling, and analytical results. The patented chemical vapor deposition process bonds the coating to stainless steel; alloy; ceramic; and glass, making a high-tolerance, durable coating even under extreme temperatures and pressures.

    SilcoNert® is made by SilcoTek Coatings, "the world's leading provider of high performance inert coatings applied by chemical vapor deposition (CVD)."
