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

The present invention relates to an analyzer () which includes a placement part () for placing an analysis piece, and a photometric measurer () for photometric measurement of the analysis piece (). In the analyzer (), the placement part () holds the analysis piece () in such a way that a row of reagent pad () on the analysis piece () lie in right-and-left directions (D, D). The photometric measurer () is farther from a front than the placement part (). The analysis piece () placed on the placement part () is conveyed from front toward rear (Direction D), with the row of reagent pads () laid in right-and-left directions (D, D), toward the photometric measurer ().
