System suitability criteria

 

4PL model

 
 
  Most of the suitability criteria options have an associated section that controls what action is taken if a suitability criterion fails.
 
For information only
 Yes / No
If  selected, this criterion will be marked "For Information Only" in the report. This option enables users to set criteria that they wish to track or investigate, but are not to be regarded as part of the regulatory report.
Continue assay on failure
 Yes / No
If selected, the report analysis will continue  to the next steps even  if a criterion fails.
Print RP on failure
Yes / No
If selected, and the "continue" option is also selected, the report will print a value for the RP despite criteria failure.
