Multiple-Level Calibration Sequences
Recalibrating With Multiple Groups of Standards
There are two different types of samples, A and B that need to be analyzed.
The analysis for sample type A requires a 5 µl injection and a stoptime of 8
minutes.
The analysis of sample type B requires a 2 µl injection and a stoptime of 5
minutes.
For sample type A:
•
there are 3 calibration standards of different concentrations and 6 samples,
•
each sample must be analyzed once,
•
the calibration standards must be analyzed in duplicate and re-analyzed
after every 2 samples,
C1 C2 C3 S7 S8 C1 C2 C3 S9 S10 C1 C2 C3 S11 S12 C1 C2 C3
•
The calibration standards of type A are in positions 1, 2 and 3 of the
autosampler tray and the 6 sample vials are in positions 7 to 12, and
•
the samples and the calibration standards use the same method called
METH1.
For sample type B:
•
there are 3 calibration standards of different concentrations and 9 samples,
•
each sample must be analyzed once,
•
the calibration standards must be analyzed twice and re-analyzed after
every 3 samples,

•
the calibration standards of type B are in positions 4, 5 and 6 of the
autosampler tray and the 9 sample vials are in positions 13 to 21, and
•
the samples and calibration standards of type B use different methods.
The samples use METH2 and the calibration standards use METH3. These
methods contain the same analytical parameters and differ only in the
analysis stoptime.
