Attempts to use gas chromatography for determination of the actual content of sucrose in sugar juices

Attempts to use gas chromatography for determination of the actual content of sucrose in sugar juices. Pietrzykowski, Tadeusz; Gruszecka, Halina; Borys, Andrzej; Kubacki, Stanislaw (Inst. Przem. Cukrowniczego, Warsaw, Pol.). Zesz. Probl. Postepow Nauk Roln., 187, 145-52 (Polish) 1977. CODEN: ZPPRAW. DOCUMENT TYPE: Journal CA Section: 44 (Industrial Carbohydrates) Section cross-reference(s): 60 The concns. of sucrose (I) [57-50-1], raffinose (II) [512-69-6], .beta.-glucose [492-61-5], sorbitol [50-70-4], .alpha.-glucose [492-62-6], and fructose [57-48-7] in corn sugar juice were detd. by gas chromatog. using the following optimum conditions: 4 mm I. D. glass column filled with Gas Chrom Q 100/120 mesh contg. 1% Ov-101 silicone oil, heated at 6.degree./min rate from 100.degree. to 300.degree.; the carrier gas was Ar flowing at 60 cm3/min. The effect of II concn. on the accuracy of I detn. and a comparison of the accuracy of I detns. by polarimetry and gas chromatog. were evaluated statistically.
