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,

• 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,
