Standard QC Sample
Description
A sample of known specification that is inserted into a group of samples either:
- During sample preparation to measure the ability to repeat analytical results given the preparation process, or
- During analytical preparation or at point of analytical measurement to measure the ability to repeat analytical results given the inherent bias within the method used,
to assess the accuracy (a measure of the bias of the method) of the analytical process and set the Standard Status.
Properties
| Primary Analytical Type | Standard |
| 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 | <empty> |
| Duplicate Original Sample | <empty> |
| Spike Original Sample | <empty> |
| Standard Code | The code of a standard material. |
| Standard Lot Code | The code of a standard lot associated with the standard material. |
Processes used to Create Standard QC Samples
- Appending/Overwriting QC for a job scheme where the QC mask has a QC mask member with an Analytical Type of Standard, its QC Type Code is a QC type that has Analytical Type of Standard, and its Secondary QC Type Code is not defined.
- Creating a standard 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 Standard.
The sample's Primary QC Type Code must be a QC type that has an Analytical Type of Standard.
The sample's Standard Code must be a standard that has a QC Type of Standard.
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.
