We assess the landscape of new sample preparation instrumentation, supplies, and accessories introduced over the past 12 months.

Sample Preparation Perspectives’s yearly report on new sample prep products introduced in the preceding year.

This month we’ll take a look at Quick Polar Pesticides (QuPPe), comparing and contrasting it with QuEChERS and noting how we can learn from previously developed methods as we strive for improvements.

The QuPPe method expands on QuEChERS to tackle highly polar compounds.

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.
