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…
Determination of Oxygen Saturation and Photoplethysmogram from Near Infrared Scattering Images
Yong-U Ri, Young-Hui Pyon, Kye-Ryong Sin
The near infrared scattering images of human muscle include some information on bloodstream and hemoglobin concentration according to skin depth and time. This paper addressed a me…
Relative Distribution of Water Clusters at Temperature (300-3000K) and Pressure (1-500MPa)
Yong-U Ri, Chang-Sob Kwak, Kye-Ryong Sin
At 300-3000K and 1-500MPa, variations of relative contents for small water clusters (H2O)n (n=1~6) were calculated by using statistical mechanical methods. First, 9 kinds of small…
