Abstract
A safety device for distributing the carrier liquid of a chromatography apparatus having a carrier liquid source, a carrier liquid reservoir provided with an entrance and an outlet, an overflow conduit, a conduit for conveying the carrier liquid toward the chromatography apparatus, and three interdependently controlled valves respectively located between the exit of the reservoir and the overflow conduit, between the entrance of the reservoir and the carrier liquid source, and between the carrier gas source and the reservoir exit. The device is usable for distributing the carrier liquid of a liquid-phase chromatography apparatus wherein the carrier liquid is pushed by a carrier gas.
