<p>The present invention relates to a deaerator 2 including: a liquid distribution space; decompression spaces 25A, 25B, and 25C; gas permeable films 21A, 21B, and 21C to partition these spaces; and a pump 22 for discharging a gas of the decompression spaces 25A, 25B, and 25C to the outside; and a liquid chromatography apparatus, provided with this deaerator 2. The deaerator 2 further includes gas partial pressure variation control means 23A, 23B, 23C, 25Ab, 25Bb, 25Cb, 29A, 29B, and 29C for controlling a variation in a partial pressure of a specific gas in the decompression spaces 25A, 25B, and 25C.</p> |
