Understanding Data, Data Review and Data Management for Chemical Testing

Course Description:

The objective of the course is to present techniques for data handling, review, and evaluation/verification.  The course is for laboratory personnel applying the TNI Standard in chemistry laboratories.  The fundamental concepts include review of calibration curve calculations, maintaining data records, reporting results to clients, applying internal data review procedures, understanding the TNI requirements, and evaluating quality control results in chemistry laboratories.  This course will identify the basic QC measures or concepts, discuss how each should be prepared and the rationale behind the frequency of analysis, how the associated samples results can be evaluated based on QC results and the significance and impact of the results on the related sample set.

The course is based on a combination of essential quality control concepts outlined in TNI Environmental Laboratory Standard Volume 1 Modules 2 and EPA 40 CFR Part 136.7. Examples from various technical disciplines (radiochemistry, chemistry, etc.) will be used to illustrate how the concept is used in different situations.

Test methods specify certain QC measures that must be performed. In some cases, there is little information on how to evaluate the results, and there is rarely any published justification for performing the measure. Many analysts perform the QC measures because “the method or the TNI Standard requires it”, but do not understand the purpose of the measurement, or how the results help to characterize the quality of the related sample set. Data associated with “Bad” or ‘Unacceptable” QC data is traditionally thought to be unusable and subject to rejection by the data user. Understanding the underlying principles of QC measures help laboratories and clients make informed decisions from sample results.

Intended Audience:

This course is designed for analysts, laboratory quality staff, laboratory technical directors, data reviewers, and data users.
