## .. CSOLN>M ..... addition into MEAS
Function Dispense calibration solution into 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. Within a CAL loop, it defines
that the calibration solution should be dispensed into the measuring
vessel.
The calibration solutions can be dispensed manually, with the
6.5611.010 Pipetting equipment, or via the 695 Autosampler, but not with
a 685 Dosimat or 700 Dosino. On manual addition with the CSOLN>M
instruction the prompt CSOLN "CSoln.name" "Mass conc." > M appears
showing the name and concentration of each calibration solution. In
additions with the 695 Autosampler, the calibration solutions are
transferred in turn to the measuring vessel from the sample rack.
Comments • 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.
On manual addition, a name should also be entered for each solution
in the parameter CSoln.name which then appears in the message for
addition.
• The addition volume valid for all calibration solutions must be entered
in the V0.CSoln parameter on the "SUBSTANCES/ Calibration" page.
• 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:
Pos. Position number on the sample rack
(freely selectable, only with 695 Autosampler)
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)
• If the entire analysis solution is changed each time following the
recording of the calibration curve, a RINSE instruction must be in-
serted in the CAL loop which resets the volume bookkeeping in the
measuring vessel to 0 (see also RINSE). If its parameter Cycles > 0
is set, the measuring vessel is also rinsed by means of the two
rinsing Dosinos connected to the 746 VA Trace Analyzer or the 695
Autosampler. If no rinsing Dosinos are connected, the prompt
Change measuring vessel to change the solution appears.
• Without a RINSE instruction, the volume in the measuring vessel is
added continuously. This can be utilized for the recording of calibra-
tion curves in which the calibration solutions are prepared each time
by manual addition of a concentrated standard solution to the analy-
sis solution.
