Translating ChemStation Sequences and Batches

ChemStation Translation Table
Translating ChemStation Sequences and Batches

ChemStation (CS) sequences and batches correspond to the Sequences in Chromeleon. Chromeleon uses all information available in the ChemStation sequence or in the ChemStation batch to create a new sequence with the same name. A message appears if this sequence already exists. You can either overwrite the old sequence or cancel the import.

The table below lists the parameters that are available for a sequence and/or batch in ChemStation and their equivalents in Chromeleon:

ChemStation (CS)	Chromeleon
Comment (of a CS sequence)	Title
Instrument	Timebase
Operator Name (of a CS sequence)	Created by
Last modification time (of a CS sequence)	Created
Current CM user (user who imported the data)	Last Update by
Date/time of import	Last Update
-	Locked
-	Preferred RDF file
-	Preferred channel

Some ChemStation sequence and/or batch settings cannot be mapped directly to Chromeleon settings:

Cal Level: Used for ChemStation calibration; not used in Chromeleon. In Chromeleon, the corresponding information is available in the Amount column of the QNT Method.
Inj/Location: Indicates the number of replicates. The corresponding number of samples will be generated for the Chromeleon sequence.
Interval: If the interval value for one of the standards is > 0, the ChemStation sequence runs in a special mode: The standard samples are injected first; then the unknown samples are injected. After x unknown samples have been injected (where x is defined by Interval), one or more standards are injected again. After importing, a sequence is created in Chromeleon in which standards are injected again after x unknown samples.

The ChemStation does not name the calibration standards; the names are automatically generated with a prefix and counter. Chromeleon needs the exact file name for data import and thus, uses the same algorithm.
