The reason for not using acetone in order to rinse quartz UV cell is to be explained. Concept introduction: A quartz UV cell is a small tubular container having straight edges, with a square or circular cross section. When a quartz UV cell is rinsed with acetone, the acidic or basic residues in the cell, catalyzes aldol condensation of acetone, precipitating ketones , which affects the spectrometric readings. In an aldol condensation reaction, an enolate ion reacts with a carbonyl compound, thus producing β - hydroxy ketone or β - hydroxy aldehyde , followed by dehydration, producing a conjugated enone.
