6 Q&As About XRD Testing
XRD test is one of the commonly used tests, but there are still many students who don’t know much about it. In this article, Drawell will introduce the problem of the XRD test to you. 1. What is the use of XRD, can you see its purity? Or can you see that it contains some kind…
Getting to Know Raman Spectrometer Right Now
Raman spectrometer（known as Raman Spectrum Analyzer） mainly determines the molecular structure of substances through Raman shift and can perform quantitative and qualitative analysis on samples such as solids, liquids, gases, organic substances, and polymers. The Raman spectrometer has 100 SERS libraries and 3000 constant substance libraries, which can quickly and accurately detect illegally added, chemically…
6 Frequently Asked Questions about Raman Spectroscopy
Raman spectrometers are the most common laboratory testing instruments. As a professional Raman spectrometer manufacturer, Drawell will answer your frequently asked questions about Raman spectrometers. 1. What is the difference between laser Raman spectroscopy and infrared spectroscopy? First of all, we need a pictorial explanation. The infrared spectrum is “concave” and the Raman spectrum is “convex”….
What Is the Application of Raman Spectroscopy in Coal Analysis?
Coal is a complex organic macromolecule composed of multiple functional groups and multiple chemical bonds. From the perspective of chemical structure, coal is a short-range ordered and long-range disordered amorphous solid organic matter, which obtains the structure of its aromatic crystal nucleus. Parameters are important content. And the best aromatic nucleus detection instrument is the…
Application of Raman Spectrometer to Heterostructure in ZnSe Materials
In the semiconductor industry, Raman spectrometers can assist the industry in studying the fundamental properties of semiconductor materials. Semiconductors containing single elements, such as silicon (Si), germanium (Ge), and semiconductors composed of multiple components, such as zinc selenium (ZnSe) and gallium arsenide (GaAs) semiconductors. In the material manufacturing stage, the characteristics of these semiconductor materials will…
What is FTIR? What Can FTIR Measure?
Fourier Transform Infrared Spectrometer is referred to as FTIR Spectrometer or Fourier Infrared Spectrometer. It differs from the principle of dispersive infrared spectroscopy and is an infrared spectrometer developed based on the code of Fourier transform of the infrared light after interference. How does Fourier Transform Infrared Spectroscopy (FTIR) work? Light from an FTIR light…
What are the Methods for Testing and Analyzing Samples by Using AAS?
In the work of analyzing test substances, the pretreatment of samples is a very complicated problem. It is one of the most important links in the analysis and detection work, and it is also one of the main ways for us to analyze the source of detection errors. Therefore, this paper summarizes four basic pretreatment methods…
How To Adjust The Absorption Sensitivity of Atomic Absorption Spectrophotometer?
Atomic absorption spectrophotometer (hereinafter referred to as AAS) will decrease in sensitivity after using it for some time. This will directly lead to an increase in the detection limit of the instrument, even exceeding the requirements of the verification regulations, so it is judged to be unqualified. The following takes flame atomization atomic absorption as…
Is The X-Ray Fluorescence Reliable For Gold Detection?
The use of portable X-ray fluorescence across the industry has been remarkable over the past few years. Originally born in the alloy and scrap metal detection industry, the technology was later determined to be effective in environmental field monitoring, particularly contaminated land and remediation work. It can be said that the use of portable XRF in soil science…
4 Reasons for Spectrophotometer Measurement Error
A spectrophotometer is an instrument that takes advantage of the selective absorption of light by substances and uses purer monochromatic light as incident light to measure the absorption of light by substances, to perform qualitative or quantitative analysis of substances. Frequently used spectrophotometers include AAS spectrophotometer, UV spectrophotometer, Nano spectrophotometer, etc. Measurement errors often occur during use. How…
