模式滤光法测定蔗糖

Detection of Sucrose by Mode-filtered Light Method

在流速为0.76mL/min的条件下,利用模式滤光法在线测定了不同浓度的蔗糖溶液,其响应范围为0—60.0%(w/w),模式滤光强度与蔗糖溶液浓度呈线性关系,线性方程为I=3673-5249C,线性相关系数r=0.9992。考察了该传感器的重现性和精密度,并对蔗糖实际样品进行了加标回收率的测定,回收率在92.2%—105.1%之间。

An online method named mode-filtered light was used to detect sucrose solution, which intensity showed linear with solution concentration , the equation can be described as I=36730-5249C, r= 0. 9992 at the concentration of 0--60. O%（w/w）. The proposed method showed good reproducibility and preeisiom The recoveries of added sucrose was between 92.2 % and 105.1%.
