Analysis of gamma-amino butyric acid in the germinated brown rice by pre-column derivatization with 2, 4-dinitrofluorobenzene
Hyok-Chol Ri, Jong-Ho Yun, Kye-Ryong Sin +1
This paper reports the analytical method for gamma-amino butyric acid in the germinated brown rice by liquid chromatography. GABA was derivatized by pre-column derivatization with…
Determination of Trace Moisture Content in Dimethylacetamide by Gas Chromatography
Yong-A Choe, Chan-Hyon Han, Kye-Ryong Sin
Dimethylacetamide is used as a solvent in polymer processing and moisture in DMA affects the morphology and mechanical properties of the polymer products. This paper describes a me…
Determination of carbohydrates in infant milk powders by ultra-performance liquid chromatography with evaporative light scattering detector and BEH HILIC column
Hyon-Hui Ri, Yong-A Choe, Jong-Ho Yun +1
The possibility of carbohydrate separation in BEH HILIC (Ethylene Bridged Hybride, Hydrophilic Interaction Liquid Chromatography) column was studied by ultra-performance liquid chr…
Bonding charge distribution analysis of molecule by computation of interatomic charge penetration
Yong-U Ri, Young-Hui Pyon, Kye-Ryong Sin
Charge transfer among individual atoms in a molecule is the key concept in the modern electronic theory of chemical bonding. In this work, we defined an atomic region between two a…
Influence of temperature and humidity on the detection of benzene vapor by piezoelectric crystal sensor
Chan-Hyon Han, Yong-A Choe, Jong-Ho Yun +1
The effects of temperature and humidity on the estimation of air pollution by benzene by using the piezoelectric crystal gas sensor were studied. Polyvinylchloride films were used…
Interaction of Tannin with Bovine Serum Albumin by Fluorescence Spectrometry
Kim Dong-Il, Choe Son-Ae, Sin Kye-Ryong
Interaction between tannin and bovine serum albumin (BSA) was examined by the fluorescent quenching. The process of elimination between BSA and tannin was the one of a stationary s…
