By using an independent IO card, 64 TTL signals can be exported to control maximum 60 tubes and maximum 4 relay controlling events.

Whether to do the tube cycle, the repeat number of tube cycle, and which tubes to analyses can be set and taken real-timely. Other than the tube cycle, ordinary manual injections can be taken as well.

Two channels of signals can be acquired simultaneously, and useful peaks can be grafted from one channel to another to make subsequent work easier.

The warning concentration thresholds of various gases and the warning concentration ratio of alkyl/alkene can be set to trigger a warning at the end of each analysis. If the concentration of methane and oxygen come into the fire damp explosion triangle, a warning will be made automatically.

Analysis time and results of each named tube are put into database automatically, where a historical report can be made by the index of time or the index of tube name. Historical curve can also be made to show the concentration trend for each gas.
