Exhaled Breath = 78.04% Nitrogen + 13.6%-16% Oxygen = CO2 Car Exhaust = Carbon Dioxide + Carbon Monoxide + Sulphur Dioxide + Nitrogen Oxides + Hydrocarbons How do we know this? Gas detection in Continuous Emission Systems (CEMS), combustion analysers and environmental monitoring are key to ensuring that the world we live in is monitored for its pollution and environments we work in are safe to do so as gases can be detrimental to life. Knight Optical provide a number of optical components that are used in Gas Detection Systems. We can also provide interference bandpass filters that work within the IR, front surface mirrors, gas cells and singlet lenses and window made from Germanium (Ge), Calcium Fluoride (CaF2), Silicon (Si), Quartz/ Fused Silica, Magnesium Fluoride (MgF2) and Sapphire (Al2O3).

R427A, also known as Forane® 427A, is an HFC blend. It is a non-toxic, non-flammable, zero-ODP (Ozone Depletion Potential) refrigerant. R427A has the lowest GWP of R22 retrofit replacement refrigerants. All fluorocarbon refrigerant gases contain one or more carbon and fluorine atoms and are organic compounds. Atoms of chlorine, hydrogen and bromine may also be present.
