A spectrometer is a common tool used by various scientists to determine information about an object or substances through the analysis of its light properties. Unknown compositions broken down into basic elemental components or lights emitted from far away galaxies can be used to determine information ...
The spectrometer uses a permanent dipole magnet and a phosphor screen and is designed for an energy range of 15–150 MeV. The main requirements that determine the features of this spectrometer are as follows: the location of the basic elements in a vacuum chamber of limited volume and ...
Through a mass spectrometer determines its N2 under high temperature signal detection, considered the NH3 has decomposed. 翻译结果4复制译文编辑译文朗读译文返回顶部 Through mass spectrometry test to determine if it appears in the heat 2 N NH signal that is 3 the decomposition. ...
Using DL-assisted data processing and reconstruction methods, this wavelength splitting functionality can enable an intelligent and miniaturized spectrometer platform for optical integration. Fig. 1: Plasmonic chirped gratings for on-chip spectrometer. a Illustration of the plasmonic chirped grating being ...
Protein content was determined using a Cary Eclipse Fluorescence Spectrometer (Varian, Palo Alto, CA) as described previously (17). Briefly, aliquots of 1 to 3 μl of whole cell lysates were mixed with 2 ml of 8 m urea in 10 mm Tris-HCl, pH 8.5. The fluorescence was measured at 295...
Protein concentration was determined using predicted extinction coefficients and 280 nm absorbance measured on a NanoDrop spectrometer (Thermo Scientific). Circular dichroism spectroscopy Circular dichroism spectra were collected using a Jasco 815 spectropolarimeter with all measurements taken in Phosphate ...
(Additional file1: Fig. S2b). To determine the levels of oxidative DNA damage, we measured accumulation of 8-oxoguanine (8-oxoG) in genomic DNA [35]. Basal levels of 8-oxoG were similar in patient and controls, but increased 8-oxoG levels were observed in LB-OXR1ΔEx18upon H2O2...
(EI) ionization, is used to remove an electron from an analyte molecule so that it can be analyzed by the electrical and magnetic fields of the mass spectrometer. EI, however, is a “hard” ionization source that can cause molecules to fragment, or break into multiple pieces. It is ...
The optical spectrometer is a key device in modern scientific research and industrial applications1,2,3,4. This device has been widely used to extract rich physical information from all types of materials and targets. And it can also be integrated into other types of optical instruments to acqui...
