Ozone (O3) is a highly reactive form of oxygen that consists of three oxygen atoms, enabling it to break down contaminants and pollutants effectively. It’s abundant in the earth’s atmosphere and is routinely generated as a byproduct of human activities. But ozone is also a powerful process gas with a raft of industrial applications. The powerful oxidizing properties of ozone make it ...
The preparation of accurate calibration gas standards depends on the precise regulation of gas flows by devices known as mass flow controllers (MFCs). Ensuring MFCs are performing accurately requires careful evaluation of each process mass flow’s gas conversion factors (known as K-factors or GCF). Here, we take a look at why gas conversion factors are important, and explain how to calculate ...
CO2 gas mixers are essential equipment throughout biological research and industrial biotechnology. In this article, we look at the applications and advantages of CO2 gas mixers and see why they offer advantages over pre-mixed gas supplies.
