## .. SMPL/M ..... V.fraction ........mL V.total .........L
Function
Sample volume has been added to the measuring vessel (MEAS) on the
747 VA Stand.
Parameter
Range; Default value / Meaning
V.fraction
0.010...50.000 mL; -
Fractional volume
With diluted samples, here the volume fraction of the total volume
V.total
which has been added to the measuring vessel must be
entered. The following condition holds:
V.fraction
≤≤ V.total
V.total
0.10 mL...100000 L; -
Total volume
With diluted samples, here the total volume of sample and dilution
solution must be entered. The following condition holds:
V.total
≥≥ V.fraction
Description
The
SMPL/M
instruction defines the sample volume in the measuring
vessel (MEAS) on the 747 VA Stand.
With undiluted samples (
V.fraction
and
V.total
blank), the sample
volume is given either by
S0
(on entry of
S0
as a volume) or by
S0/S2
(on entry of
S0
as a weight,
S2
is the density in g/mL).
With diluted samples (
V.fraction > 0
and
V.total
≥≥ V.fraction
), the
sample volume is given by
V.fraction
, irrespective of the entry of
S0
.
You will find further details on the sample size in the description of the
parameter
Sample size/S0
in section 5.4.4.
Comments
The
SMPL/M
instruction can not be used in operation with the 695
Autosampler.
