Cyclic Multiple-Level Calibration Sequences
Cyclic Multiple-Level Calibration Sequences
This type of sequence uses different calibration samples to recalibrate a
multiple-level calibrated method.
The following example describes a two-method sequence comprising method A
and method B to analyze two groups of samples. Both methods are
multiple-level calibration methods that will recalibrate automatically at
defined intervals.
For each method the Sequence Table has three entries:
• Two calibration levels:
• Sequence lines 1 and 2 in method A.
• Sequence lines 8 and 9 in method B.
• Five entries for the samples:
• Sequence line 3 through 7 in method A.
• Sequence line 10 through 14 for method B.
The calibrations are specified at regular intervals by the recalibration interval
entry in the Sequence Recalibration Table.
• Method A will recalibrate after every two samples.
• Method B will recalibrate after every three samples.
The Sequence Table below is truncated to simplify the example.
