Blank QC Sample
Description
A sample of known blank specification that is inserted into a group of samples either:
- During sample preparation to measure the calibration status of equipment used for the preparation process, or
- During analytical preparation or at point of analytical measurement to measure the calibration status of equipment used for the preparation of measurement process,
to assess the calibration state of the analytical instruments and set the Standard Status.
Properties
| Primary Analytical Type | Blank |
| Primary QC Type Code | <empty> |
| Secondary Analytical Type | N/A (This is the actual content of the field, and implies that secondary assessment is not applicable.) |
| Secondary QC Type Code | The code of a QC type that has a Primary Analytical Type of Blank. |
| Duplicate Original Sample | <empty> |
| Spike Original Sample | <empty> |
| Standard Code | The code of a blank standard material. |
| Standard Lot Code | The code of a standard lot associated with the blank standard material. |
Processes used to Create Blank QC Samples
- Appending/Overwriting QC for a job scheme where the QC mask has a QC mask member with an Analytical Type of Blank, its QC Type Code is a QC type that has an Analytical Type of Blank, and its Secondary Analytical Type not is defined.
- Creating a blank sample via the CCQCSM—QC Sample Modification application from workbook.
QC Assessments Performed
- Assessment of the Accuracy of Analysis, due to the fact that its Primary Analytical Type is Blank.
The sample's Primary QC Type Code must be a QC type that has an Analytical Type of Blank.
The sample's Standard Code must be a standard that has a QC Type of Blank.
The sample's Standard Lot Code must be a standard lot within the standard.
The standard lot's Specification Code must be a specification that has a Specification Type of Standard.
The specification contains limits for the matching Scheme Code, Scheme Version, Analyte Code and Internal Unit Code.
