What are the sensitive lines of spectral elements?
Generally refers to the spectrum line with a low excitation potential, often an atomic line (point arc line), and a few are ion lines (spark line). The sensitive lines appearing in the spectrum are related to the light source and spectroscopic instrument used and the test conditions.
Comparison of LIBS laser induced spectrometer and fluorescence spectrometer
Laser, laser, these words are used to describe the amplification of light generated by excited radiation. Laser was discovered by Einstein, a great physicist, in 1916, and was not applied until 1960. The question of this technology. ..
Direct reading spectrometer resistance grounding preparation
During the installation of the direct-reading spectrometer, the manufacturer generally requires grounding. According to the corresponding specifications, the direct-reading spectrometer manufacturer needs to dock and assist the manufacturer. In order to stabilize the instrument state, the installation grounding preparation is also for better analysis effect and safety.
Chuangxiang CX-5500 fluorescence spectrometer method for rock and mineral measurement
The CX-5500 spectrometer of Chuangxiang Co., Ltd. was used to measure the rock and mine spectra in the wild. The excitation light source of the spectrometer can be selected, Ag target, Au target, W target, Rh target, etc. The tube pressure and tube retention can be adjusted freely. The instrument ...
The configuration accuracy of direct reading spectrometer is related to these factors
The design of the direct-reading spectral optical structure is very important, which determines the relationship between the light of incident energy in the spectrometer and the light energy irradiated on a single detector pixel. The main factors affecting the accuracy of the spectrometer are grating, incident fiber or narrow ...
The advantages and disadvantages and economic benefits of direct reading spectrometer
A spectrometer is an optical instrument that separates polychromatic light into a spectrum, also known as a spectrometer, and is widely recognized as a direct reading spectrometer. The principle of direct reading spectrometer is to use the high temperature of arc (or spark) to make the elements in the sample directly vaporize from the solid state and be excited ...
What is the principle of the high-frequency infrared carbon and sulfur analyzer you purchased?
Determination of carbon and sulfur in metals, including ICP method, direct reading spectroscopy, X-ray fluorescence, mass spectrometry, chromatography, activation analysis, etc., each has its advantages and scope of application, most manufacturers choose to use Frequency infrared carbon and sulfur analyzer, this is a ...
What factors influence the analysis result of carbon and sulfur analyzer?
At present, carbon and sulfur analyzers are generally used for the analysis of carbon and sulfur elements in metals. In the use of analytical instruments by various manufacturers, there are often cases where the repeatability or reproducibility is not satisfactory. In this regard, the first doubt is the failure of the instrument, but often after ...
Directly read the core accessories of the spectrometer, you must know before buying!
At present, direct reading spectrometers can be divided into three types according to the core components, PMT technology, CCD technology, CMOS technology, and there are direct reading spectrometers with two core components. If one device can really replace another, and sex ...
