4.2 Stream
In the GC1000 Mark II, 31 streams can be used. Parameters needed to be specified for
streams are:
• Stream valve number
Any one stream valve number from among the numbers of 1 to 31 should be specified for a
stream.
If the stream valves are automatic, the stream valve of the specified valve turns on/off. If
the stream valves are manual, this setting does not have any effect on the operation.
The same stream valve number can be specified for different streams. When multiple
measurements are performed in one stream, the same stream valve number should be
specified.
A standard sample stream should be specified as one of the streams.
• Method number
Any number from 1 to 4 should be specified for a method number.
There are three types for the stream:
• Measurement stream
Used for measuring process samples.
• Validation stream
Comparing measured results before and after calibration, or checking if the GC1000 Mark
II is operating properly can be performed using a standard sample. The validation stream
is used for standard sample measurement in such case.
• Calibration stream
Used for measuring a standard sample at calibration. The calibration stream may be used
in combination with the validation stream.
