Abstract:
1. A chromatography apparatus comprising: (a) a chromatography column defining a column lumen, (b) flow-through chromatographic separation medium disposed in the column lumen, said separation medium defining liquid flow-through passages, (c) a detector, (d) a conduit for an aqueous liquid eluent stream providing fluid communication between said detector and said chromatographic separation medium, (e) a catalytic gas elimination chamber in fluid communication with said conduit and including a catalyst for combining hydrogen and oxygen gases, or for catalytically decomposing hydrogen peroxide, or both, in said eluent stream to form water and reduce the gas content in said eluent stream, and (f) a delay conduit disposed between said detector and said catalytic gas elimination chamber, said delay conduit having a total flow-through volume of at least 0.5 times the total volume of said separation medium flow-through passages.
