Producing high red index caramel for sauce from xylose mother liquor;

Research of relation between color ratio and red index of caramel color and pH;

How to improve red index of caramel;

Reducing yellow index of acrylonitrile-butadiene-styrene copolymer

The affecting factors that are caused by the quantity of the sample,the warm-up time duration of the chromatic instrument and the correction time duration of the standard board in the yellow index measurement of polypropylene products are discussed.

The super white ABS resin featured of melt flow index of 45-60 g/10 min, Izod impact strength of 167 J/m, tensile strength at yield of higher than or equal to 40 MPa and yellow index of lower than or equal to 19.

The gas chromatogram fingerprint characteristics of C 9-C 17 branched and cyclic alkane, the light hydrocarbon fingerprint correlation and the light hydrocarbon maturity in the crude show that the hydrocarbon sources of all wells in the Chengbei 30 buried hill reservoir are same.

ASP oil Production contribution of the separated layers detected by crude oil chromatographic fingerprint technique;

Aim at the localization of the technique of gas chromatographic fingerprint,which is difficult of being applied to commingled production of three and more layers oil.

The assessment of oil connectivity makes up an indispensable part of the field production and field management scheme, in which the oil chromatographic fingerprint technology can play an important role.

Advanced GC fingerprint technique provides an economy, simple and valid method for reservoir dynamic monitor.

Partition experiment and chemical simulation of GC fingerprint compounds were carried out in one reservoir of Gangxi area in Dagang oilfield.
