Chromatogram File Name

This field contains a template for creating chromatogram names. Up to 254 characters may be entered including spaces and international characters, the following characters are, however, forbidden: /, \, :, *, ?, ", <, >, |.

The automatic filename composition option is a powerful tool. The station uses a set of variables preceded by the "%" character as described below. After an analysis is terminated each variable is replaced by its current value. Variables may be combined at will. The current value is displayed in parentheses above the editing field and in the Information table of the Instrument window.

List of common file name variables

Variable	Meaning	Example of use
%n	Sample serial number, also called Counter, which is automatically incremented every time the chromatogram is created (when multiple Snapshot functions are used during the same acquisition, and the resulting chromatogram is either created or not, the counter is incremented only once). The value may be modified depending on the place - for single measurements in the Single Analysis dialog, the Counter field or for sequences in the Counter value field in the Sequence Options dialog of the particular sequence. The counter values for single analysis and sequence are separate. Alternatively, the counters may be set automatically to 0 or 1 each time the Instrument is opened by the Reset when Open Instrument checkbox from the Counter section of the User Options - General dialog (for single analysis) or through Counter section in the Sequence Options for sequence counter.
%P	Name of the project.	Pollutants
%J	Name of the method ( without .MET suffix).	DDTInWater
%s	Name of the sequence (without .SEQ suffix).	BalticSea
%V, %v	Vial number (Only for the sequence table or when an autosampler is used in single analysis).
%I, %i	The number of the injection taken from a given vial (Only for the sequence table).
%L, %l	The Sequence Line Number is a number of the row in the Sequence Table (Only for the sequence table).
%c	Number of an Instrument.
%e	Name of an Instrument.
%g	Analyst name/ User name.
%Q	Sample (contents of the Sample field).
%q	Sample ID (contents of the Sample ID field).
%f	Vial barcode.	BarCode-00001
%%	The sign for percentage.	%
%T	Time of the analysis start (in the format hh-mm).	%T=13-41
%D	Date (in the format dd_mm_yyyy).	%D=24_02_2009

 

Additionally, some of the above variables allow for special formatting - namely variables for counter (%n), vial number (%v or %V), sequence injection number (%i or %I), sequence line number (%l or %L) and Instrument number (%c). These allow for defining the particular number of places used, counter in addition allows to define step by which the counter will be incremented.

 

Variable	Meaning	Example of use
%xn	Selects fixed number of places for the variable. The number is formatted using preceding zeroes where needed (e.g. for x=3:).	%3n = 001-999
%n(x)	Selects step for the counter, (e.g. for x=5:).	%n(5)=1, 6, 11

The above variables may also be used in Sample and Sample ID fields both for individual injections and in a sequence table. In order to use the variables in Sample and Sample ID fields you must also use it in the filename.
