Function

Add sample volume to the measuring vessel (MEAS).

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 is added to the sample 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 is used for the manual or automatic addition of

the sample volume to the measuring vessel (MEAS) on the 747 VA
Stand:

−

In manual addition or addition with the 6.5611.010 Pipet-
ting equipment, the prompt

SMPL "V.sample" > M

for

manual addition of the sample volume

V.sample

appears

in the program run.

−

In automatic addition with the 695 Autosampler, the sam-
ple volume is transferred from the sample vessel on the
sample rack defined on the 1

sample data line to the

measuring vessel.

With undiluted samples (

V.fraction

and

V.total

blank), the sample

volume is given either by

(on entry of

as a volume) or by

S0/S2

(on entry of

as a weight,

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

You will find further details on the sample size in the description of the
parameter

Sample size/S0

in section 5.4.4.
