Technical Problem
在这种情况下若长时间采样，随着箱体内温室气体的浓度升高，可能会影响温室气体在液相及气象之间的传质效果，从而影响最终的检测结果
Benefits of technology
[0018]本实用新型中的温室气体自动检测装置利用漂浮圈将采集箱漂浮于水面上，采集箱内部被分隔板分隔为左右两个采集空腔，分别对水面产生的温室气体进行收集，两个采集空腔分别对应连接于采集单元，采集单元对待检测气体进行采样收集，随后由检测单元对采集单元得到的待采样气体进行分析检测，同时检测单元检测采集空腔的状态，从而对待检测气体进行准确和全面的分析；在检测过程中，两个采集空腔各自独立工作，其中一个采集空腔采样完成后，由采集单元向该采集空腔通入新鲜空气，由单向排气阀排出所有的待检测气体，从而进行下一个采样检测周期，而在此时另一个采集空腔为采样完成状态，以便进行检测工序，采集工作可以更加平稳地进行。由此即可实现两个采样空腔的独立采集和交替采样检测，互不干扰，且可提高检测效率，同时可分别检测后进行平均值计算，以提高检测的准确性。该温室气体自动检测装置可以有效提高采样和检测的稳定性以及检测结果的准确性。
