Things to Look For in an SO2 Analyzer

 As you shop for an SO2 analyzer, there are a number of things you should look out for. A functional analyzer should give you the confidence to quickly and accurately run your regular sulfite assays. Additionally, the kit should include everything that is required to perform ~50 tests; therefore, it should come with a beaker, a syringe, reagents, pipettes, reagents and an electrode. Read on to learn more about this analyzer:

About SO2 Analysis

Sulfur dioxide, chemically denoted as SO2 is measured in various applications. This gas is used to preserve food. As a result, it needs to be regulated to meet government- set criteria for safe consumption by human beings. SO2 is also measured in exhaust systems and control to ensure it does not cause environmental pollution. In other sectors, SO2 analysis is performed in cement production plants to control the industrial process.

The UV DOAS System

This system comes with a SO2 analyzer that can fit each of the above mentioned applications. Studies show that UV DOAS equipment is designed to provide data that is accurate and realistic, especially in comparison to other conventional gas monitoring machines.

You can calibrate your UV DOAS equipment with the right SO2 analyzer and use it to detect gases present in that area, include sulfur dioxide. The equipment also continuously provides updates on changes in the concentration of this gas.

With this equipment, you get a highly sensitive and accurate titration system that will audibly and visually alert you when the electrode detects the endpoint. This makes it the most convenient equipment to use in the detection and analysis of SO2.

Unlike other products in the industry, it does not rely on color changes. Therefore, it eliminates guesswork in sulfite tests, especially when the test subject is a food product or beverage, like ride wine.

How It Works

The SO2 analyzer is an improvement on the old school analysis methods. Instead of colorimetric analysis, you get digital detection indicators that are more effective and reliable.

The titrant will react with sulfite from the test subject. Then audible and visual indicators give you a signal when you titrate all the free sulfur dioxide. Since the test endpoint is more sensitive that in sulfite titrations, you will get a sharp and clear signal.

Overall, finding the right SO2 analyzer is important. It should be affordable, reliable and dependable. The analyzer should also adhere to set standards on manufacture. This way, you will get your money’s worth in terms of functionality and durability.
