How to Choose the Correct Sample Preparation Approach for Modern Analytical Applications

This presentation was recorded on August 26, 2014.


The goal of any sample preparation technique is to obtain the required quality of results while at the same time minimizing the overall effort and investment. It’s extremely important to strike this balance in sample preparation. Given thenumerous options to choose from, selecting the right sample preparation approach can seem overwhelming and frustrating. Because of this, sample preparation might be overlooked, which will lead to analysis issues, increased instrument maintenance, and breakdowns. However if a systematic approach is taken based on the application requirements, such as trace versus residue analysis, analytical instrumentation (LC or GC with conventional detectors or MS, MS-MS), it can be quite easy to meet the goal to achieve a balance between quality of results and effort/investment.. In this web seminar, we will discuss how to choose the correct sample preparation technique — from mechanical and functional filtration, solid supported liquid extraction, QuEChERS, through to solid phase extraction based on sample types and applications. We will also compare these techniques in order to understand their limitations and benefits.
