Recent progress in fast sample preparation techniques

Sample preparation is a critical step in complex sample analysis which effect to sensitivity, selectivity, speed, and accuracy of analytical results. The goal of sample preparation is separation and enrichment. Separation and enrichment are entropy reduction procedures which cannot happen spontaneously. On account of consuming over two thirds of analysis time, sample preparation becomes the bottleneck issue in analytical chemistry. Therefore, fast sample preparation has been received much attention. In this review, a comprehensive survey on progress in fast sample preparation techniques for complex sample in the last 2 years has been composed from more than 180 references. Four approaches for entropy reduction of sample preparation system were generalized, they are energy exchange acceleration, materials-based acceleration, size reduction acceleration, and integration acceleration. Moreover, we highlight the most interesting acceleration techniques, including field-assisted, materials-based rapid mass tra...
