Oxygen calibration gas: 3 things to know

What is Oxygen calibration gas

Oxygen gas can also be referred to as dioxygen. It is also referred to as dioxygen because it is a bond of two oxygen atoms, is the second-most abundant element in the Earth’s atmosphere, accounting for 21 percent of the air we breathe, well behind nitrogen’s 78 percent. Pure oxygen gas has a specific gravity of 1.105. A gravity of 1.105 would mean it would sink under the rest of the atmosphere if there were no wind or air movement on our planet. The Atomic Number of this element is 8, and the Element Symbol is O.

Oxygen (O2) calibration gas is for the use of calibration of gas detectors. Many different gas detectors are capable of detecting O2, as set these gas detectors to need to be calibrated for safety reasons.

Zero air

Zero Air is air which is filtered to ensure it contains less than 0.1 parts per million (PPM) of total hydrocarbons. Essentially a mixture of oxygen and nitrogen, zero air is required for laboratory applications which would be negatively affected by the presence of hydrocarbons or small levels of sulphur or nitrous oxide. These gases can sometimes be present in the air due to pollution.

How to store Oxygen gas

Oxygen calibration gas is a colourless, odourless, and tasteless gas. Like with most calibration gases, proper storage is crucial. It is essential that you store oxygen calibration gases in a cool and ventilated area which preferably is closable. Keep the oxygen calibration gas cylinder away from any consumable beverages.

How to transport oxygen gas

To transport oxygen gas either by road, sea or air. You need to have the right documents. To carry oxygen gas legally you need to have Safety Data Sheets (SDS), Material Safety Data Sheet (MSDS) or Product Safety Data Sheet (PSDS). SDS sheets are an essential component of product stewardship, occupational safety and health, and spill-handling procedures. Safety Data Sheets (SDS) is a globally used system for cataloguing information on chemicals, chemical compounds, and chemical mixtures. There are different requirements for transporting oxygen gas, depending on the country. Find out more about how to move gasses in a proper way here.
