A practical introduction to separation and purification techniques for the beginning organic chemistry laboratory

Abstract

Separation techniques have always been important for a successful chemical career. This author addresses some important considerations for training students.

Designing and Conducting a Purification Scheme as an Organic Chemistry Laboratory Practical

“…Students must develop practical skills in the organic chemistry laboratory, but building these skills through "cookbook" procedures does little to prepare students for more realistic situations in a professional laboratory (1). Students who have been trained to follow directions cannot decide how to adapt a known technique to new situations and may not even know which technique they should use to purify a mixture (2)(3)(4). Although good lab skills are crucial, the ability to devise a plan of action when faced with a familiar or slightly unfamiliar scenario is equally important (5).…”

“…Gas chromatography is a technique for separating and analyzing the composition of chemicals in a sample mixture. [83][84][85] A gas chromatograph (GC) consists of the following main components; the inlet into which the sample mixture is injected, the column in which the mixture is separated into its components, and the detector that converts the received chemicals into electronic signals (Figure 3.1). 86,87 The most crucial process occurs in the column, which is filled with a specific material called the stationary phase.…”
