## .. SMPL>M ..... V.fraction ........mL V.total .........L

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 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.
