Gas analysers are essential when measuring the concentration of a specific gas within a mix of gases. This can be accomplished through several different types of analysers – from infrared to spectroscopic.
Real-time analysis is great when seeking to maximise efficiency and safety. These devices are nuanced and typically require some professional assistance. To understand exactly what is going on, let’s dive into how gas analysers work.
What Do You Need to Analyse Gas?
Whenever you seek to analyse and monitor gaseous species, you have to utilise the optical properties of the gas. To do this, you will need a light detector and light source, and you’ll need to know the characteristic behaviour of the gaseous species you are looking for. This allows the gas to be separated from the other gases present in the same mixture.
There is a multitude of gases in existence. Deciding which one you are looking for plays a role in how you go about analysing gas.
Safety and efficiency are always targeted when analysing gas. Depending on your specific needs, you may look into gas analyses for environmental, automotive, process, or industrial usage.
Types of Analysers
There are a multitude of gas analysers to choose from. Some types include zirconia oxygen analysis, process gas chromatography, and hydrogen purity analysis, among others.
At Australian Dynamic Technologies, we offer infrared gas analysers. With multiple models available, there are a few factors to understand. Of course, the staff at Australian Dynamic Technologies can also assist in all decision-making prior to purchase.
How Do They Work?
An infrared gas analyser measures trace amounts of gases through identification of absorption levels in a particular sample of air. Essentially, this means measuring how much infrared light is absorbed in the air. If the sample has lots of a certain gas, the light absorbs more at a certain frequency.
Our analysers take a sample of the air and search for trace gases in the atmosphere. Different molecules will be absorbed through different frequencies of infrared light. The sensors will be able to report back with the concentration amounts of certain molecules.
The analysers operate through two chambers. The first is a reference chamber, and the second is a measurement chamber. The infrared light filters through on one end, passes through the analyser, and reports the concentration levels.
What to Do with Gas Analysis Results?
Once the results are in, decisions can be made. This is where the professional staff of Australian Dynamic Technologies can greatly assist you. Depending on the type of concentration found, various actions can be taken.
For example, if the report shows high carbon monoxide levels, you’ll want to identify steps to lower that risk. These steps might include dirty air filters, improper fuel delivery system operation, and more. No matter what the cause might be, carbon monoxide presents a risk.
More than that, analysis results can show high or low levels of oxygen, carbon dioxide, nitrous oxide, and more. Essentially, basic gases in the atmosphere can be pinpointed and measured. Some, like carbon monoxide, present a health and safety risk. Others reflect upon the efficiency of the vehicle, industry, environment, or process.
Altering the efficiency based on gas levels can lead to increased production and results. The analysis might spur action into identifying leaks and other issues. These may be small – but they might lead to greater problems down the road. Either way, even the smallest of leaks or clogs can translate to lost time and money.
