Question
Before running one form of this technique by hand, one can wash with tri·ethyl·amine to “deactivate” materials used in this technique to reduce that material’s acidity and ability to decompose compounds. Rapid depressurization or exothermic solvent addition in this technique can lead to visually apparent “cracking,” forming regions that are prone to leakage. It’s not distillation, but samples can be dry-loaded by adsorbing them onto a powder in the (*) “flash” form of this technique, which uses a glass adapter connected to a nitrogen line. Hexanes are used to “pack” silica in a cartridge before loading samples in this technique. Polar solvents are used in the reverse-phase form of this technique. For 10 points, name this technique in which a mobile phase elutes and separates compounds down a stationary phase. ■END■
