温度对膜进样质谱溶解气渗透效率影响的研究
Study on the Effect of Temperature on Dissolved Gas Permeation Efficiency of Membrane Injection Mass Spectrometry
摘要
Abstract
As an important marine equipment,underwater mass spectrometry has the advantages of good consistency,strong directivity,and simultaneous detection of multiple substances,and has been widely used in the field of deep-sea exploration.However,the sampling efficiency(membrane permeation efficiency)of underwater mass spectrometry is highly susceptible to the influence of ambi-ent temperature,which increases the difficulty of dissolved gas concentration inversion and reduces the accuracy of detection results.This article focuses on the deep sea environment(temperature change range:4-35℃)and conducts research on the impact of temperature on membrane permeabil-ity efficiency.The results show that in this temperature range,the membrane permeation efficiency of dissolved gas increases approximately three times.At the same time,the temperature rise and fall experimental results show that the membrane permeation efficiency is not only related to the tempera-ture at the current moment,but also affected by the historical temperature.That is,the influence of temperature on the membrane permeation efficiency has a hysteresis effect.This study quantifies the effect of temperature on membrane permeation efficiency,reveals the phenomenon of temperature lag in membrane sampling technology,and provides a method reference for accurate inversion of dis-solved gas concentration.关键词
