摘要
DS-1型碳水连测仪设置新型热导检测器,能适用于氧气做载气,从而有助于解决在有机物存在下总碳的准确测定,并为实现碳水连测开拓了新途径。该仪器灵敏度高、检出限低、线性范围宽。不仅能满足化探样品以及岩石、土壤中测定碳、水的要求,而且能应用于单矿物中碳水的测定。该仪器采用电磁阀为气路转换以实现时间程序控制,使操作简单、成本较低、易于推广应用。
A new type of thermal conductivity detector is devised to avoid the harming effects of organic matters on the determination of CO2 and H2O+. The detector is advantageous owing to its low detection limit, wide linear response and short period of detection, and the instrument is ideal for determining CO2 and H2O+ in regional geochemical reconnaissance samples, rocks, minerals and soils.
