Hydrosol obtained with Explorer (an Alchemia Solution Still) Corine Lormel, PhD Samples often contain very different molecules. In analytical laboratories, finding the instrument which will identify and quantify them is the first step. For this purpose, the chemist must ensure that the chosen method can “separate” the compounds of interest but also makes them “visible”

Benoit Roger (Ph. D.), Hubert Marceau (B. Sc., chemist), Alexis St-Gelais (M. Sc., chemist) Have you ever tried cooking pasta atop a high mountain? OK, this is a weird introduction, but you’ll see the link. Everybody ‘’knows’’ that (pure) water freezes at 0 °C and boils at 100 °C and in everyday life, this is
