Exploring the Possibilities of High-Throughput Sample Preparation
June 1, 2014

Sample preparation has often been viewed as the bottleneck in analytical procedures. Surveys have shown that time is typically the most frequent problem area for sample preparation procedures. While newly developed extraction techniques address time, modern chromatography advances are also moving towards faster separations. Based on these considerations, what is high-throughput sample preparation? Do modern extraction methods adequately address the issue of time? How can we address the analytical need for speed?
