      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.

      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:

      Disposal and Recycling of Gas Cylinders

      Paul Fry

      Recycling gas cylinderOnce you’re done with your calibration gas cylinder it’s important to safely dispose of it. All CAC GAS cylinders can be returned to us for proper disposal. Some can be reused, others cannot. No cylinders should be put into general waste and it can be difficult to find a recycler who will accept cylinders.

      How dangerous is a calibration gas cylinder?

      Paul Fry

      How dangerous is a calibration gas cylinder? What to be aware of and tips for handling.

      Calibration gas cylinders are considered dangerous goods. But, how dangerous are they, really? After all, most gas calibration gases are classified as “non-toxic, non-flammable” gases.

      The Importance of Purging

      Paul Fry

      How to choose the correct purge system for your application.

      Purging is an important part of a good calibration procedure and should always be practised when handling dangerous gases. Purging ensures that you have control over which gases are in your gas delivery system, and therefore which gases are being exposed to internal components, sensors, or other equipment. It also helps to prevent unwanted reactions from taking place, which can greatly increase the service life of related components.

      Tapered Thread Fittings

      Paul Fry

      In order to deliver gases from a cylinder to the point of use, a gas delivery system is used. This can be as simple as a single cylinder regulator or a complex system involving a manifold, pipelines, line regulators, outlet points, or a long list of many other components.

      However your system is designed, there will be many gas-tight connections. In this article, we’ll focus on one type of fitting: tapered thread fittings.

      General Rules for Designing Custom Gas Mixtures

      Paul Fry

      We are often asked for many different gases for the same applications. When possible, the required gases can be combined into the same cylinder to reduce the overall gas cost. When creating custom gas mixtures you must be aware of potential issues from mixing different compounds together.
