Soil Sample Preparation for Pesticide Analysis

Preparing soil samples for pesticide analysis is a crucial step in ensuring the safety of all consumers. Typical soil samples for analysis are often a heterogeneous mix that are unable to be directly analyzed; thus, the handling and homogenizing of the sample must conducted with the proper tools and techniques in order to obtain a reproducible and meaningful result.

John Philip Walters (1)
John Philip Walters, Ph.D. (1938-2026), was an analytical chemist who spent 17 years researching the physics of spark-discharge emission spectroscopy at the University of Wisconsin-Madison before moving to St. Olaf College in 1982, where he became best known for pioneering a role-playing undergraduate laboratory model that had students take on professional roles to mirror real analytical-chemistry work. His 1991 three-part series on the approach in Analytical Chemistry earned him the ACS Division of Analytical Chemistry's J. Calvin Giddings Award in 1993, and he continued extending his understand-the-system teaching philosophy into computer-controlled instrumentation well into his later career.
