Brown Bag 12: Handling Samples and Sample Integrity


Course Description:

This class will cover requirements from Volume 1 Module 2 Section 5.8 of the TNI Environmental Laboratory Standard. 

Expected Benefit of Training:
Sample handling is the transition between field activities and laboratory analysis. Things can go wrong from the beginning if procedures have not been established. Sample integrity is probably the most important aspect of quality data. Labs will benefit by ensuring their procedures and records increase efficiencies and decrease the number of non-conformances.

Learning Objectives:

  • Identify what is a sample or subsample. 
  • Understand how to uniquely identify a sample. 
  • Understand what constitutes an abnormality or departure from normal or specified conditions. 
  • Understand container and preservation requirements. 
  • Knows Chain of Custody form requirements. 
  • Understand what constitutes proper storage, handling, and preparation. 
  • Understand how to use ID codes to document and/or provide traceability to preservation, subsamples, extracts, digestates, sample containers. 
  • Understand linking of field codes and laboratory codes. 
  • Understand the element of an appropriate sample acceptance policy including sample rejection or documentation of any decision to proceed with analysis. Understand documentation and record keeping requirements. 
  • Identify elements required for receipt of sample containers. 
  • Understand document retention protocol. 
  • Understand difference between legal chain of custody and routine sample handling. 
  • Understand sample storage protocols and means of disposal of samples, digestates, leachates and other extracts or sample preparations.

Intended Audience:

This course is designed for Accreditation Bodies, Assessors, Internal Auditors, Quality Managers, Analysts, and Laboratory Managers.
