Must clarification by flotation – wineanorak

Aug 08, 2020  Silica helps create large flocs, and can be used with gelatin, but needs to be added first. These adjuvants will inactivate any enzymes that are present, so if enzymes are used then need to be added first. There are also some plant protein adjuvants which can be used instead of gelatin (which is animal-derived) for vegan-friendly wines.

Chromatography - Wikipedia

Chromatography is a physical method of separation that distributes components to separate between two phases, one stationary (stationary phase), the other (the mobile phase) moving in a definite direction. The eluate is the mobile phase leaving the column. This is also called effluent. The eluent is the solvent that carries the analyte.
