High Resolution Low Temperature Spectrophotometry of Cytochromes ,am box Dewars to vacuum space Dewar systems have been developed. Use of an on-line computer for the summation of spectra recorded from low temperature specimens has been made to increase resolution and sensitivity of the spectrophotometers. Originally the summation operation was a manual procedure.过去分词 发表于 2025-3-26 02:19:45
Application of Infrared Spectroscopy to the Study of Gas-Solid Interactions Between S02 in a Simulations occurring between gaseous sulfur dioxide and various solid adsorbents. In this instance, we utilized infrared spectroscopy to study the gas-solid interactions between sulfur dioxide in a simulated flue gas and various solid adsorbents. In situ spectroscopic studies were conducted in a hightempe就职 发表于 2025-3-26 07:06:18
Qualitative Limits of Detection of Specific Compounds Obtained by Trapping Gas Chromatograph Fractioection for any given compound which can be achieved with a method designed to trap a G.C. peak for further analysis. This paper presents the limits of detection found attainable in the qualitative analysis of specific organic compounds. These limits were established by utilizing an activated charcoaMorsel 发表于 2025-3-26 10:28:43

A Controlled-Atmosphere Plasma Arc for Emission Spectrography of Nonmetal Elementstructed a controlledatmosphere plasma arc which effectively excludes air from the plasma. Selected organic compounds that contained nonmetal elements were mixed with a solvent essentially free of those elements. The weightpercents of the nonmetal elements were estimated from the diatomic spectral baorient 发表于 2025-3-26 20:18:22
