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。 At the flow rate of 0.76mL / min, the concentration of sucrose solution was linearly determined by the mode filter method with a response range of 0-60.0% (w / w) , Linear equation I = 3673-5249C, linear correlation coefficient r = 0.9992. The reproducibility and precision of the sensor were investigated. The recoveries of spiked sucrose samples were measured with the recoveries of 92.2% -105.1%.
