## .. CSOLN/M ..... solution added into MEAS

Function

Calibration solution is already in the measuring vessel (MEAS).

Description

The

CSOLN/M

instruction is used for the recording of calibration curves

with the techniques

cal.crv.

and

int.std.

with the manual 747 VA

Stand. Within a CAL loop, it defines that the calibration solution is already
located in the measuring vessel (MEAS).

Comments

The

CSOLN/M

instruction can not be used in operation with the 695

Autosampler.

In contrast to the

CSOLN>M

instruction, with

CSOLN/M

no prompt to

add the calibration solution appears during the program run. As a
new calibration solution must be used for every concentration, within
the CAL loop it is mandatory to insert a

RINSE

instruction which

resets the volume bookkeeping in the measuring vessel to 0 (see
also

RINSE). To ensure that the prompt

Change measuring vessel

to change the solution appears, its parameter

Cycles > 0

must be

set.

The number of calibration solutions is defined with

n

in the

CAL)n

instruction. A valid mass concentration

Mass conc.

must be entered

on the "SUBSTANCES/Calibration" page for each of these solutions.

In the

V0.CSoln

parameter on the "SUBSTANCES/Calibration" page,

the volume valid for all calibration solutions that have been added to
the measuring vessel (MEAS) must be entered.

If work is performed with

Auto.samples = on

, on the "SAMPLES"

page sample data lines must be entered in immediate succession for
all n calibration solutions with the following holding for their parame-
ters:

S1...S3

Sample identifications (only entries of the last
calibration solution are used and stored)

Method.call

Name of the method +

.C

(for mode calibration)

Sample Size/S0

Entry of an asterisk

*

(value not used, but field must not be blank)

For permanent storage of the coefficients of the calibration curve
determined in the recording of the calibration solutions, the method
must then be copied from the working storage to the method memory
(this occurs automatically with

Auto.batch = on

).
