Use of a mixing chamber for sample preparation and multiple collection in sequential injection analysis: determination of sulfate in wines

A sequential injection system for determination of sulfate in wines was developed. It was based on the formation of BaSO4, measured turbidimetrically at 420 nm. As sample dilution and acidification were required, both sample and acid were sent to a mixing chamber placed in a lateral port of the sele...
