Degassing impact of mobile phase affects instrument function state directly ,during the anal-ysis of HPLC. In this paper ,a method was developed to review and optimize degassing mode of mobile phase ,with water as mobile phase and oxygen as target .Dissolved oxygen meter was used for mensuration changing disciplinarian of oxygen content in water with different degassing mode of mobile phase. Chan-ging disciplinarian of oxygen content in water was got by ultrasound method ,vacuum filtration method and on-line vacuum degassing method. It was important to test changing disciplinarian with time changing and different velocity of flow. and operation process of degassing mode was optimized ,the result has reference significance for HPLC analysis.
