Retention Time Windows Sample Clauses

Retention Time Windows. Retention time windows are used in gas chromatography , ion chromatography, and high-performance liquid chromatography analysis for qualitative identification of analytes. They are calculated from replicate analyses of a standard on multiple days. The procedure and calculation method are given in SW846, USEPA Method 8000C. The center of retention time window is established for each analyte and surrogate using the retention of the midpoint standard of the initial calibration. For methods other than mass spectroscopy, these windows are updated daily using the absolute retention time s in the initial calibration verification. When the retention time is outside of the acceptance limi ts, corrective action shall be performed. This applies to each continuing calibration verification subsequent to the initial calibration verification and to the LCS. After the system problems have been resolved and system control has been re -established, each sample analyzed prior to identifying the system problems shall be re -analyzed since the last acceptable retention time check. If corrective actions are not performed, the appropriat e flag, as described in Section 5.0, shall be applied to the sample res ults.
