An ICP optical spectrometer suffers from many challenges when faced with high salt samples. This work describes the selection of the best components and accessories for this application.
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.
