Determinations u sing the internal standard are normally programmed
on the OP.SEQUENCE page with the following basic structure:
:
C (CAL Loop start for calibration
C CSOLN>M or CSOLN/M Addition of calibration solution to
: measuring vessel
C RADD>M Addition of internal standard to
: measuring vessel
C (REP Loop start for replication
C SEGMENT Seg1 Call-up of the segment
: (measurement of the calibration solution)
C REP)n Loop end, n = number of replications
C ØMEAS Switch off voltage (solution change)
C RINSE Reset volume bookkeeping
C CAL)n Loop end, n = number of calibration solutions – 1
:
D SMPL>M or SMPL/M Sample addition to the measuring vessel
D RADD>M Addition of internal standard to
: measuring vessel
D (REP Loop start for replication
D SEGMENT Seg1 Call-up of the segment
: (measurement of the sample)
D REP)n Loop end, n = number of replications
:
As in the previous example, with the same number of replications for
calibration and determination in the internal standards method the
illustrative program can be shortened as follows:
:
D SMPL>M or SMPL/M Sample addition to measuring vessel
C (CAL Loop start for calibration
C CSOLN>M or CSOLN/M Addition of calibration solution
: to measuring vessel
RADD>M Addition of internal standard
: to measuring vessel
(REP Loop start for replication
SEGMENT Seg1 Call-up of the segment (measurement of the
: calibration solution or sample)
REP)n Loop end, n = number of replications
C ØMEAS Switch off voltage (solution change)
C RINSE Reset volume bookkeeping
C CAL)n Loop end, n = number of calibration solutions – 1
