About the course

Very often there are quality issues in the laboratory, which affect the standards that are intended and mean that quality can be in doubt for our clients. During various stages of processing we need to use quality tools to maintain confidence in the products. The analysis of each stage means that total confidence can also be achieved. This course is designed specifically for Laboratory technicians and those involved with quality control during the chemical process utilizing the most accurate tools and terms of measure for control. It contains full explanations in an easy to understand format and regular discussions to reinforce learning throughout.

Course Objectives

Upon successful completion of this course, the delegates will be able to:

  • Introduction to quality assurance in the laboratory and how principles of measurement are understood and utilized
  • Principles of chemical measurement and the principles of quality assurance involved and used to their maximum
  • Accurate measurement and recording of analysis and results of sampling of each step of chemical processes using quality tools
