This column has discussed both sample size and homogeneity previously. However, sample collection is just as important. Too often, analysts are dependent on clients bringing the sample to the laboratory. This month, we take a look at devices and processes for obtaining samples outside of the laboratory.

We explore the aspects of sampling that are of highest importance in an analytical scheme. Devices and processes for obtaining appropriate samples outside of the laboratory are presented.

In this column, importance of the knowledge of the fundamental principles underlying sample preparation is emphasized.

These seven case studies capture and expand on lessons presented at ChromTalks.

This yearly report on new products introduced in the preceding year, since March 2020, covers sample preparation instrumentation, supplies, and accessories.

The application of temperature is frequently employed to enhance analytical extractions, especially with solid samples or volatile analytes. This article explores the role of temperature in analytical extractions.
