The present invention relates to a deaeratorincluding: a liquid flow space; reduced-pressure spacesA,B, andC; gas permeable filmsA,B, andC that separate these spaces; and a pump for discharging gas from within the reduced-pressure spacesA,B, andC to the outside, and to a liquid chromatograph equipped with the deaerator. The deaeratorfurther includes gas partial pressure variation suppression meansA,B,C,Ab,Bb,Cb,A,B, andC for suppressing variations in partial pressures of a specific gas in the reduced-pressure spacesA,B, andC.

Degasifier and liquid chromatograph equipped therewith

The present invention relates to a liquid chromatography apparatus X, which is provided with a deaerator. The liquid chromatography apparatus X is further provided with a dissolved oxygen density adjusting means for maintaining a density of dissolved oxygen in an eluting solution to be supplied to a columnconstant. Preferably, the dissolved oxygen density adjusting means is configured so as to adjust the density of the dissolved oxygen in the eluting solution by adjusting a degree of decompression in a decompression space of the deaeratorbased on a measurement result by temperature measurement meansA,B, andC for measuring the temperature of the eluting solution.

Liquid chromatograph

A liquid homogenizing unit comprising a feed flow channel (), a discharge flow channel (), a first intermediate flow channel () communicating with the feed flow channel (), and a second intermediate flow channel () communicating will the first intermediate flow channel () and discharge flow channel (). The first intermediate flow channel () extends in a direction which crosses the second intermediate flow channel ().
