Connecting to the nitrous oxide supply
Compression nut
1. Connect the blue nitrous oxide hose (coming from the back of the spectrometer) to the nitrous oxide
regulator.
2. Tighten the connection using the double wrench technique. Hold the fitting on the regulator with one
wrench and tighten the compression nut on the gas hose with the other wrench.
NOTE: If you intend to perform analyses using only the air-acetylene flame (i.e. you do not intend to analyze
elements that require a nitrous oxide-acetylene flame), you will not require a supply of nitrous oxide.
When shipped from the manufacturing site the blue nitrous oxide hose is fitted with a plug. Leave this
plug in the free end of the hose when it is not connected to a supply of nitrous oxide.
