Analytical chemistry

Abstract

Many of the guiding principles for optimizing chromatographic separations are appropriate for inclusion in an undergraduate analytical course.

Determination of Niacinamide in Lotions and Creams Using Liquid–Liquid Extraction and High-Performance Liquid Chromatography

“…Liquid–liquid extraction is a sample preparation technique that has been used in chemistry laboratories for many years . In the late 1960s, Robert V. Dilts and L. B. Rogers separately wrote about the importance of including separation techniques in the undergraduate analytical chemistry curriculum. , Rogers states that the principles for optimizing separations are appropriate topics for undergraduate analytical courses . This idea, that separation, spectrophotometry, and sample treatment are important parts of undergraduate chemistry curriculum, has been repeated over the years .…”

“…4,5 Rogers states that the principles for optimizing separations are appropriate topics for undergraduate analytical courses. 5 This idea, that separation, spectrophotometry, and sample treatment are important parts of undergraduate chemistry curriculum, has been repeated over the years. 6 These opinions have been well accepted, and many experiments involving HPLC have been designed for undergraduate laboratory courses.…”
