Transit spectrophotometry of the exoplanet HD 189733b
Context. We present a new primary transit observation of the hot-jupiter HD 189733b, obtained at 3.6 μm with the Infrared Array Camera (IRAC) onboard the Spitzer Space Telescope. Previous measurements at 3.6 microns suffered from strong systematics, and conclusions could hardly be obtained with confidence on the water detection by comparison of the 3.6 and 5.8 microns observations. Aims. We aim...
متن کاملImproved ultraviolet spectrophotometry of serum theophylline.
We present an improved method for ultraviolet spectrophotometry of theophylline in serum. We studied various extraction techniques aimed at eliminating interferences from co-extractable serum constituents. In the resulting modified procedure, 1 ml of serum is required and a salt-solvent pair of ammonium sulfate and chloroform/hexane is used for extraction. The solvent forms the top phase after ...
متن کاملMultivariate Analysis of Perfumes by Ultraviolet Spectrophotometry
An efficient, fast and cost-effective method for detecting adulteration in perfumes by UV spectroscopy and multivariate analysis is proposed. Classification of perfumes, either as original or fake, was accomplished with the spectroscopic data using chemometric techniques such as principal component analysis (PCA), soft independent modeling of class analogy (SIMCA) and linear discriminant analys...
متن کاملExtreme hemodilution with PEG-hemoglobin vs. PEG-albumin.
Isovolemic hemodilution to 11% systemic hematocrit was performed in the hamster window chamber model using 6% dextran 70 kDa (Dx 70) and 5% human serum albumin (HSA). Systemic and microvascular effects of these solutions were compared with polyethylene glycol (PEG)-conjugated 5% albumin (MPA) and PEG-conjugated 4.2% Hb (MP4). These studies were performed for the purpose of comparing systemic an...
متن کاملAn Extreme Ultraviolet Spectrometer
A concept and preliminary design of an Extreme Ultraviolet (EUV) spectrometer is presented. The spectrometer is based on a gas ionization chamber and an advanced eight-electrode electron focusing system to form a narrow electron beam on a photodiode aperture. The design is modeled with the SIMulation of IONs (SIMION) tools and shows the ability to scan through the spectral range of 20.0 – 40.6 ...
