1 = Ar - Argon 13 = Kr - Krypton
2 = CH4 - Methane 14 = N2 - Nitrogen
3 = C2H2 - Ethyne 15 = Ne - Neon
4 = C2H4 - Ethelyne 16 = NH3 - Ammonia
5 = C2H6 - Ethane 17 = NO - Nitrogen Oxide
6 = C3H6 - Propylene 18 = N2O - Nitrous Oxide
7 = C3H8 - Propane 19 = O2 - Oxygen
8 = C4H10 - Butane 20 = XE - Xenon
9 = CO - Carbon Monoxide 21 = UserGas1
10 = CO2 - Carbon Dioxide 22 = UserGas2
