    • PURPOSE:To stably perform quantitative analysis with high accuracy by a method wherein a solution containing saccharides is separated through a separating column of liquid chromatograph and hydrolized under heating while continously adding an acid or alkali solution thereto, and then colorimetry is effected by continuously adding reducing sugar coloring reagent to the solution hydrolized. CONSTITUTION:A given quantity of a solution 10 containing saccharides such as non-reducing saccharides, oligosaccharides or polysaccharides is sampled by a sampler 3 and eluting liquid 1 is sent to the sampler by a quantitative pump 2. The saccharide solution within the sampler 3 is fed to a separating column 4 of liquid chromatograph and separated with the eluting solution 1 fed thereto subsequently, so that the eluted solution enters a mixing portion 5. Meanwhile, a saccharide hydrolizing reagent (acid or alkali solution) is sent to the mixing portion 5 from a bottle 22 by a quantitative pump 20 in such a manner that its pulsatory current is reduced through a resistance coil 40. Then, the mixed solution is fed to a heating reaction tube 6 and hydrolized at temperature of 70-150 deg.C. Thereafter, the solution is fed to a mixing portion 7 to be mixed with reducing sugar coloring reagent and is reacted in a coloring reaction tube 8 at temperatur of 80-120 deg.C. The reacted solution is measured in a detecting section 9 by a spectrophotometer or colorimeter and the result is recorded on a recorder 38.
    • 目的:通过将含有糖的溶液通过液相色谱仪的分离柱分离并在加热下水解并在其中连续加入酸或碱溶液的方法,以高精度稳定进行定量分析,然后通过连续加入还原 糖着色试剂溶液水解。 构成:通过采样器3对给定量的含有糖类的溶液(如非还原性糖,寡糖或多糖)进行取样,并通过定量泵2将洗脱液1送入取样器。取样器3内的糖溶液为 进料到液相色谱仪的分离柱4,并随后用洗脱液1分离,使洗脱溶液进入混合部分5.同时,将糖类水解试剂(酸或碱溶液)送入混合部分5 通过定量泵20从瓶22通过电阻线圈40使其脉动电流减小。然后,将混合溶液供给到加热反应管6中,并在70-150℃的温度下水解。 然后,将该溶液送入混合部7,与还原糖着色试剂混合,在着色反应管8中在80-120℃的温度下反应。 通过分光光度计或色度计在检测部分9中测量反应溶液,并将结果记录在记录器38上。
