10.5.5 Technical Acceptance Criteri

10.5.5 Technical Acceptance Criteria for the Initial Calibration.
10.5.5.1 The calculated %RSD for the RRF for each compound in the calibration table must be less than
30% with at most two exceptions up to a limit of 40%.
[Note: This exception may not be acceptable for all projects. Many projects may have a specific target list
of compounds which would require the lower limit for all compounds.]
10.5.5.2 The RRT for each target compound at each calibration level must be withiin 0.06 RRT units of
the mean RRT for the compound.
10.5.5.3 The area response Y of at each calibration level must be within 40% of the mean area response
over the initial calibration range for each internal standard.
10.5.5.4 The retention time shift for each of the internal standards at each calibration level must be within
20 s of the mean retention time over the initial calibration range for each internal standard.
10.5.6 Corrective Action.
10.5.6.1 Criteria. If the initial calibration technical acceptance criteria are not met, inspect the system
for problems. It may be necessary to clean the ion source, change the column, or take other corrective actions to
meet the initial calibration technical acceptance criteria.
10.5.6.2 Schedule. Initial calibration acceptance criteria must be met before any field samples,
performance evaluation (PE) samples, or blanks are analyzed.
