Sampling and Sample Preparation

Speaker

Instructor: Mark Powell
Product ID: 706285
Training Level: Intermediate

Location
  • Duration: 60 Min
Sampling and sample preparation are both potential sources of variability and bias in analytical chemistry. The purpose of this webinar is to describe a scientifically-sound approach to sampling different types of analytical matrix (including liquids, gases and solids such as powder blends and tablets) and to describe the options available for sample extraction, clean-up and pre-concentration. The webinar would be useful for scientists developing analytical methods or writing sampling plans.

Why Should You Attend:

Industry regulators and quality assessors will expect to see evidence of sound approaches to sampling and sample preparation in order to ensure good method robustness. This webinar provides the necessary theoretical knowledge to enable these expectations to be met.

Sampling and sample preparation between them often account for the largest proportion of analytical error in chemical measurements. The aim of this webinar is to remind analytical scientists of the importance of these steps in the analytical process and to set out scientifically-sound practical options to minimize result variability. The contents of the webinar will be especially useful for those working to GMP or a metrological quality standard such as ISO 17025. The aim of the webinar is to help scientists design better sampling and sample preparation strategies.

Areas Covered in the Webinar:

  • Sampling
    • Why sampling matters
    • Sampling plan
