Investigation of the separation of the trimethylsilyl derivatives of carbohydrates by gas-liquid chromatography showed that this technique could be used to determine the major mono- through tetrasaccharide components of corn syrup. An improved method of derivatization was developed, applicable in the presence of up to 40 mg. water. Separations were made with SE-52 and SE-30 silicone stationary phases and with both multiple isothermal, and linear temperature-programmed operations. Component data for glucose, maltose, maltitriose, and maltotetraose, in 43 Dextrose Equivalent corn syrup, showed a relative standard deviation of 1.7 to 3.4%. Further application to the separation and determination of sucrose in the presence of corn syrup solids also was described.
