In summary, the data entered in the 1
st
sample data line are used only
for the next determination
•
if the automatic sample data transfer is switched off
(
Auto.samples = off
), and
•
if no sample data are entered in the 2
nd
line.

Sample data of sample being prepared
The layout of this line is identical to that of the lines on the "SAMPLES"
page (see section 5.4.4). The meaning of the displayed data and the
input possibilities depend on various factors:
•
With methods without sample preparation cycles, here both in the
standby mode
* READY *
and during an ongoing determination
(
* BUSY *
status) data specific to samples can be entered and
used for the next determination (see Table) when the automatic
sample data transfer (
Auto.samples = off
) is switched off.
•
In the case of methods with sample preparation cycles (possible
only with 695 Autosampler and
Auto.batch = on
), here the data
of the sample being prepared are shown and can not be
changed.
Pos.
1...160;
Position number
Position number on the sample rack of the 695 Autosampler (without
695 Autosampler this column has no meaning, however it can be
used for simple sample numbering).
The following rules apply to the position numbering:
•
All instructions concerning the sample vessel (FEED) (e.g.
SMPL/F
,
CSOLN/F
,
F>M
,
DOS>F
, etc.) are referred to the vessel at
the rack position
Pos.
defined by the position number.
•
All instructions concerning the auxiliary vessel (AUX) (e.g.
F>A
,
DOS>A
, etc.) are referred to the vessel which immediately follows
the sample vessel defined by the position number (rack position
Pos. + 1
).
•
The sequence of the positions can be freely selected for sample
solutions, but the same position number can only be entered
once.
•
With calibration solutions, all solutions must be entered in imme-
diate succession, however, the position numbers themselves can
be selected at random.
•
During series determinations without automatic transfer of sample
data
Auto.samples = off
, the position number of the current
sample is shown on the 1
st
sample data line in the parameter
Pos.
.
•
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
