Description
The Waters In-Line Degasser AF provides HPLC systems with an automatic, continuous method for removing dissolved gasses from mobile phases. The continuous running pump cycles between high-speed, to provide rapid vacuum pull-down, and low-speed, to sustain a consistent vacuum level. This unique approach enables rapid vacuum equilibration for faster eluent equilibration. The In-Line Degasser AF's continuous operating mode improves chromatographic performance for high-sensitivity applications by eliminating detector baseline drift caused by pump hysteresis in discontinuous operating modes.
