紫外荧光硫测定仪的故障排除及维护
编辑:泰州睿科分析仪器有限公司   时间:2019-07-30

        紫外荧光硫测定仪网络棋牌采用“紫外荧光法”原理。将样品引入高温裂解炉后,进行氧化和裂解。样品中的硫被定量地转化为二氧化硫。反应气体干燥脱水后进入荧光室。在荧光室中,部分二氧化硫在紫外光照射下,在激发态下转化为二氧化硫。当二氧化硫转化为基态时,发出光子,光电倍增管放大光电信号。然后由放大器放大,再由计算机处理,就可以转换成与光强度成比例的电信号。在一定条件下,反应中产生的荧光强度so2*与二氧化硫的产生量成正比,二氧化硫的量与样品中的总硫含量成正比。因此,可以通过测量荧光强度来测定样品中的总硫含量。
