Maximum Holding Times and the “Q” Data Qualifier Code
The approved maximum holding times for specific analytes are listed in the DEP SOP FS 1000 tables. Any results reported from samples not meeting the holding times specified in those tables must be qualified and reported with the “Q” data qualifier code, per rule 62-160.700, F.A.C. (Table 1 of the DEP QA Rules). The holding time limits in the DEP SOP tables do not allow for extra time to prepare or analyze samples beyond the maximum times specified.
