S600+ Instruction Manual
Revised July-2017 Chromatographs C-23
Cnas(heptane) = Cna(C7+) * splits(heptane) / 100.0
Cnas(octane) = Cna(C7+) x splits(octane) / 100.0
Cnas(nonane) = Cna(C7+) x splits(nonane) / 100.0
Cnas(decane) = Cna(C7+) x splits(decane) / 100.0
Cnas (C7+) = 0.0
Be sure to carry forward the other mole percentages from Cna to Cnas.
C.9.6 No C6+ or C7+ Handling
In systems where C6+ or C7+ breakdown is not required, update the
hexane value live from the chromatograph using the position specified
in the telemetry parameters mole ordering array. The system then treats
this value as it would any other mole percentage. Additionally, the
system copies all elements from Cna into Cnas.
C.10 Alarms, Displays, Reports, and Maps
This section provides additional miscellaneous features.
C.10.1 Alarms
The module supports the following alarms:
C.10.2 Displays
The displays for the chromatographs can be located under one of two
places on the web server or front panel depending on how the
application was configured.
For applications that assign a chromat to a station, then the
composition information can be found under:
Operator -> Station n -> Composition
where n is the station number
For applications that assign a chromat to a stream, then the
composition information can be found under:
Operator -> Stream n -> Composition
where n is the stream number
