Nitrogen is a colourless, odourless gas and is important to the chemical industry. It is used to make fertilisers, nitric acid, nylon, dyes and explosives. Nitrogen is also used to provide an unreactive atmosphere. It is used in this way to preserve foods, and in the electronics industry during the production of transistors and diodes. Large quantities of nitrogen are used in annealing stainless steel and other steel mill products. Annealing is a heat treatment that makes steel easier to work. Liquid nitrogen is often used as a refrigerant. It is used for storing sperm, eggs and other cells for medical research and reproductive technology. It is also used to rapidly freeze foods, helping them to maintain moisture, colour, flavour and texture. Nitrogen is used as a balance gas in many calibration gas mixtures.
We at Spantech provide pure Nitrogen gas cylinders and with various mixes in many ppm and % levels, in our Spancan™ A34 litre, A58 litre and A110 litre cylinders.
