Optimising Sample Preparation

1 Day

Ensure that you pick the right sample prep technique and learn how to get the best of it

Sample preparation training can help you learn or brush up on different techniques such as Liquid/Liquid Extraction (LLE), QuEChERS and Solid Phase Extraction (SPE), among others, no matter your level of experience. Learn the absolute essentials and method development tips and tricks and apply this knowledge for the betterment of your lab workflow.

A comprehensive one-day course designed to increase expertise and optimise method development time for all users of sample preparation and SPE in particular. 

The course is backed with a host of explanatory images and multimedia material from our range of e-learning products. Practical examples are included to reinforce the learning experience.

  • The need for sample preparation
  • The range of techniques available for sample clean-up
  • Liquid/liquid Extraction (LLE) and Supported Liquid Extraction (SLE)
  • QuEChERS
  • Phospholipid Removal
  • The basics of SPE and practical considerations
  • Sorbent Selection, retention mechanisms and generic protocols
  • What are the various extraction techniques offered by SPE
  • Method development and protocol troubleshooting
