TL;DR: In this article, the Working Group that produced these protocols/guidelines has now been mandated by IUPAC to prepare guidelines on the single-laboratory validation of methods of analysis, providing minimum recommendations on procedures that should be employed to ensure adequate validation of analytical methods.

TL;DR: The International Harmonized Protocol for the Proficiency Testing of (Chemical) Analytical Laboratories (IHPT) has been revised in the light of recent developments and the experience gained since it was first published as mentioned in this paper.

TL;DR: The requirements and procedures that may be used to obtain methods that have been validated `in-house', without full validation through collaborative trial, are outlined, pointing the way to international acceptance of such methods in future as the cost of carrying out full validation of methods through collaborative trials becomes prohibitory.

TL;DR: A methodology is proposed, which employs duplicated primary sampling and subsequent duplicated physical preparation coupled with duplicated chemical analyses, applied for the first time to a case study of pesticide residues in retail strawberry samples.
