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.

Sampling systems for gas measurement in wastewater applications.

Greg Shires

Water/wastewater organizations have for many years struggled with measuring gases and vapours in sewers over long periods of time.  

The physical nature of the application creates high levels of corrosive gases, heat, water and high humidity which negatively impact all sensors including catalytic, electrochemical and photo ionisation.

Gas Distribution Systems for Non-Docking Station Applications

Greg Shires

The GDS-100 Gas Distribution System was originally designed to provide an efficient method of utilizing high pressure/large volume gas mixtures with gas detection docking stations.

Although excellent for this application the GDS-100 has also proven to be a beneficial stand-alone system for both calibration and bump testing applications.

Calibrating Process Analysers with the On-Demand Flow Regulator.

Greg Shires

The ODFR-1001 is an On-Demand Flow Regulator providing flows between 0.3 – 3 litres/min. 

This regulator is ideal for calibrating or testing Process Analysers which have internal pumps to draw in the gas sample.

The regulator is available in a low pressure version for use with disposable gas cylinders up to 70 bar and a high pressure version for cylinders with pressure up to 300 bar. Both versions work identically.

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.
