Detector for volatile sulphides in surface seawater and atmosphere

表层海水与大气中挥发性硫化物检测装置

Abstract

The utility model provides a detector for volatile sulphides in surface seawater and atmosphere. The detector is has a structure that a sample collecting assembly is connected with a gathering and desorbing assembly, the gathering and desorbing assembly is connected with an oxidization detection assembly, and the oxidization detection assembly is connected with a gas circuit conversion assembly and a gas supply system. The detector for volatile sulphides in surface seawater and atmosphere has the characteristics and beneficial effects that the detector has two channels, can detect volatile sulphides in surface seawater and atmosphere at the same time without any chemical agents, does not cause secondary pollution to the environment and water bodies, and is quick and accurate in detection process, good in repeatability, stable and reliable in result and suitable for detecting concentrations of volatile sulphides in various water bodies and in particular suitable for dynamical detection by an ocean research vessel or a scientific research vessel in an underway manner. The detector can detect automatically and monitor in real time for a long time, online and continuously, so that the detector is suitable for being widely applied.
本实用新型提供一种表层海水与大气中挥发性硫化物检测装置,该装置是由样品采集组件与捕集解吸组件连接,捕集解吸组件与氧化检测组件连接,氧化检测组件与气路转换组件连接并与供气系统连接。本实用新型的特点与有益效果是:本实用新型采用双通道设计,可同时检测表层海水和大气中挥发性硫化物,无需任何化学试剂,不会对环境和水体造成二次污染,检测过程快速准确,重现性好,结果稳定可靠,适合于各种水体挥发性硫化物浓度的检测,尤其适合于海洋调查船或科考船以走航方式动态检测,并可实现检测过程自动化运行,可长时间实时、在线、连续监测,适宜广泛推广。
