Tropospheric Sulfur Dioxide Measurement Intercomparison

这项研究是关于测量对流层二氧化硫(SO2)的雾室方法参加了1994年美国国家科学基金会赞助的国际比对(GASIE)。相互比较将由特拉华大学协调，暂定于1994年9月和10月在特拉华州的刘易斯举行。来自新汉普郡大学的两名研究人员将在GASIE比对期间操作雾室方法。雾室方法对于偏远地区大气化学测量项目的现场部署似乎是可取的，因为它相当灵敏，检测下限约为20pptr(V)，似乎没有基质干扰，尺寸和重量相对较小，而且实施成本适中。雾室法测量二氧化硫的可靠性将通过参加GASIE严格的双盲比对进一步检验。这种参与是该方法在未来用于大型现场测量计划之前验证的必要的下一步。

This research pertains to the participation of the mist chamber method for measuring tropospheric sulfur Dioxide (SO2) in the 1994 NSF-sponsored intercomparison (GASIE). The intercomparison will be coordinated by the University of Delaware, and is tentatively planned for September and October of 1994 in Lewes, Delaware. Two researcher from the University of New Hampshire will operate the mist chamber method during the GASIE intercomparison. The mist chamber method appears desirable for field deployment in atmospheric chemistry measurement programs in remote regions because it is quite sensitive a detection limit of approximately 20 pptr (v) , appears to be free from matrix interferences is relatively small in size and weight, plus offers modest implementation costs. The reliability of the mist chamber method for measuring SO2 will be further tested by participation in the rigorous double-blind GASIE intercomparison. This participation is an essential next step in the validation of the method prior to its future use in large field measurement programs.
