Submilligram determination of organic sulfur using sealed tube combustion method
Autor: Ayako Satoh, Naoshige Akimoto, Keiichiro Hozumi
Publikováno v: BUNSEKI KAGAKU. 47:219-224
有機硫黄の微量定量は燃焼管法かフラスコ燃焼法が用いられているが,試料が1mg以下になると精度維持がしだいに困難になる.数年前有機ハロゲンの定量に封管燃焼法が提案され,ここでは

Functionalization on surfaces of solid materials by alcoholic plasma-polymer films
Autor: Keiichiro Hozumi, Kikuko Yoshimura
Publikováno v: Journal of Photopolymer Science and Technology. 8:369-376
Hydrophilic plasma-polymer films were prepared from 2- propyn-1-ol (propargyl alcohol, PA) on surfaces of solid materials. The polymer enhanced its wettability by increasing the amount of water added to the PA monomer. Functional property of the poly

Some Recent Approaches to Micro- and Ultramicro-Elemental Organic Analysis
Autor: Keiichiro Hozumi
Publikováno v: Analytical Sciences. 9:167-177
Automatic instrumentation has been developed for the microdetermination of various elements in organic samples ranging from 2 to 3mg. The author has devised a microanalyzer for carbon, hydrogen and nitrogen which embodies a pump system for collecting
