We compared the durability of the degassing effect when degassing online and when degassing the water in the bottle using other methods.
The degasser maintains a consistently low level of degassing for the water supplied to the flow path while allowing liquid to pass through. On the other hand, if the water in the bottle is degassed all at once, it will rapidly reabsorb atmospheric (oxygen) over time, and the degassing effect will quickly diminish.

basic information
【Results】 ○ The amount of dissolved gases in a liquid significantly affects the accuracy of qualitative and quantitative analysis in trace analysis, as well as various measurements and storage stability in the life sciences field. ○ From the trend of atmospheric (oxygen) reabsorption observed in these test results, it was found that the reabsorption rate of atmospheric (oxygen) occurs more rapidly at lower dissolved concentrations. It is estimated that to achieve a stable degassing effect with a batch degassing method, unless the liquid is stored in a sealed state after degassing treatment, the effect will rapidly diminish. ○ In this regard, online degassing can be considered a method that provides a stable degassing effect. ● For more details, please contact us or refer to the catalog.
