WORKSHEET #24: ANALYTICAL INSTRUMENT CALIBRATION TABLE
This worksheet provides a list of analytical instrumentation required to perform the laboratory analyses and the associated
calibration procedures. In addition, documentation of the frequency, acceptance criteria, and corrective action requirements are
also provided. All instruments will be calibrated according to the schedule specified by the method and instrument manual or
applicable SOPs. This worksheet will be completed upon laboratory procurement.
Calibration
Procedure
GC ICAL Initially, prior to sample
analysis
GC Second source
initial calibration
verification (ICV)
GC CCV Daily before sample
analysis, every 10
samples, and at the end of
the analysis sequence
GC/MS
ICAL
Table 24-1. Analytical Instrument Calibration
Frequency of Calibration Acceptance Criteria Corrective Action
One of the options below:
Option 1: relative standard
deviation (RSD) for each
analyte ≤ 20%
Option 2: linear least
squares regression:
r≥0.995
Option 3: non-linear
regression: coefficient of
determination (COD) r 2 ≥
0.99.
After every ICAL All analytes within ± 20%
of expected value from the
ICAL.
Method inception, CCAL
fails
All analytes within ± 20%
of expected value from the
ICAL.
Locate the source of the problem. If
expected RSD is not met, then check
for standard degradation or perform
instrument adjustment and/or
maintenance to correct the problem and
repeat ICAL.
Prepare fresh standard and re-analyze
ICV to rule out standard degradation or
inaccurate injection. If problem persists,
then perform instrument adjustment
and/or maintenance to correct the
problem and repeat ICAL.
Prepare fresh standard and re-analyze
CCV to rule out standard degradation
or inaccurate injection. If problem
persists, then perform instrument
adjustment and/or maintenance to
correct the problem and repeat ICAL.
