Container Guide

The use of correct sampling containers is crucial for preserving the integrity of the samples and complying with UKAS requirements regarding deviating (or non-conforming samples).

Examples of deviating samples include:

  • Headspace in VOC vials or BOD bottles
  • Incorrect or no separate containers for volatiles
  • Plastic containers used for organic parameters
  • No preservatives used for time critical inorganics
  • No sampling date supplied
  • Inappropriate storage temperature
  • Analysis performed outside of holding times

The standards covering this aspect of sampling are ISO 18512 for soils and BS EN ISO 5667 for waters, and include details of containers, temperature conditions and preservatives, where applicable.
