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.”

    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?

    High Accuracy Calibration with the MICRO300 Precision Regulator

    Paul Fry

    When producing a specialty gas mixture, most of the time taken to manufacture it goes into cylinder preparation to ensure that the mixture is stable. This is the single most important aspect in a quality gas mixture. If what comes out of the cylinder is not what is described on the label it will result in a poor calibration. Much time, testing, and research is invested in the development of techniques related to the interaction with cylinders and valves, solely to ensure the stability of mixtures. In general, it includes:

    What makes a good calibration gas?

    Alex Singer

    There are two types of measurements made when preparing gas mixtures. The first is measuring what goes into the cylinder (volumetric or gravimetric measurement), and the second is measuring what comes out of the cylinder (measurement based on analysis). The first is relatively simple, as you need to only have:
