Parameter Range; Default value / Meaning
• With calibration solutions, all solutions must be entered in imme-
diate succession, however, the position numbers themselves can
be selected at random.
• With the UV sample racks, the position numbers on the sample
holders are defined as follows:
6.2041.100 Sample Rack: Sample holder left 1...12
Sample holder right 13...24
6.2041.110 Sample Rack: Sample holder left 1...16
Sample holder right 17...32
Ident.1/S1 12 characters;
Sample identification 1 / Variable S1
This column can be used for optional entry of either the alphanumeric
sample identification 1 or the numeric variable S1. The following rules
hold for the entry:
• If the first character is not a number, the entire entry is interpreted
as alphanumeric sample identification 1 (e.g. Sample 456, B-56-
234-199).
• If the first character is a number or a period (point), the entire
entry is interpreted as numeric variable S1 (e.g. 125.849, 4.629e-
08). Subsequent entry of letters or special characters is no longer
possible. If you wish to enter a sample identification starting with
a number, you must thus precede the number by a non-numeric
character (e.g. #).
The sample-specific variable S1 can be used in formulae (see section
5.6.4).
Ident.2/S2 12 characters;
Sample identification 2 / Variable S2
This column can be used for optional entry of either the alphanumeric
sample identification 2 or the numeric variable S2. The same rules as
for Ident.1/S1 apply to the entry.
If the sample size Sample size/S0 is entered as a weight, S2 must
be entered as a density in g/mL (without manual entry the default
value 1.0000 is automatically entered).
The sample-specific variable S2 can be used in formulae (see section
5.6.4). If S2 has been entered as a density in g/mL, this numeric value
must be multiplied by the factor 1000 in formula calculations as all
other variables are based on the base units g or L.
Ident.3/S3 12 characters;
Sample identification 3 / Variable S3
This column can be used for optional entry of either the alphanumeric
sample identification 3 or the numeric variable S3. The same rules as
for Ident.1/S1 apply to the entry.
The sample-specific variable S3 can be used in formulae (see section
5.6.4).
