2.5.1 Nitrogen gas
The method of supplying nitrogen gas, there is a method to use liquid nitrogen, nitrogen gas cylinder,
nitrogen gas generator. This instrument does not use nitrogen gas other than stopping or adjustment.
Therefore recommend use the nitrogen gas cylinder or liquid nitrogen. The nitrogen gas generator does
not absolutely require. Please note that operating hours may be shortened depending on the flow rate of
the drying gas if using a nitrogen gas cylinder. As an approximate standard, assuming a 47L cylinder
releasing the gas at a maximum flow rate, this single cylinder would sustain the flow for approximately 5
hours. (For approximately two times of auto tuning)
