Why Optical Emission Spectrometers Need Standard Samples262024 FebOptical emission spectrometers are fundamentally based on comparative measurements. As a result, they need to be calibrated with standard reference materials to create a "calibration curve" ...Details
Why Optical Emission Spectrometers Need High and Low Standards192024 JanDuring the use of an optical emission spectrometer, the working curve can drift, leading to increased measurement errors. This drift can be caused by factors beyond the sample's elemental composit...Details
Why Optical Emission Spectrometers Require High-Purity Argon092023 JunHigh-purity argon is crucial for optical emission spectrometry. The argon used must meet the standards of GB/T 4842-2006 for high-purity argon, which means the purity must be ≥99.999% with strict lim...Details
The Role of Different Elements in Copper Alloys182023 MayAn alloy is a substance with metallic properties created by combining two or more metals, or a metal with a non-metal. Alloying allows us to create materials with superior performance and characterist...Details
What is a CCD in a Direct-Reading Spectrometer?282023 AprThe English full name for CCD is Charge-coupled Device, and the Chinese full name is 电荷耦合元件.After the Charge-coupled Device (CCD) was invented by Bell Labs in the United States in 1969, it devel...Details
Differences between CCD and PMT232021 AugChannelsPMT (Photomultiplier Tube): PMT is for point (or line) measurement and can only read discrete spectral lines. Each element corresponds to one PMT, so at least one tube is needed for each eleme...Details
Working Process of an Oxygen-Nitrogen-Hydrogen Analyzer222025 SepAs a standard laboratory instrument, an oxygen-nitrogen-hydrogen analyzer can simultaneously perform quantitative analysis to determine the content of O, N, and H elements in organic compounds, inorga...Details
Why Test for Oxygen, Nitrogen, and Hydrogen Content in Steel?062023 MayThe Harm of OxygenThe mechanical properties of steel are negatively affected by oxygen and hydrogen. Not only is oxygen concentration a factor, but the quantity, type, and distribution of oxygen-conta...Details
Terminology Related to Testing and Inspection132022 AprRepeatabilityRepeatability is the maximum difference between two independent single test results for the same sample, obtained by the same operator, in the same laboratory, using the same instrument, ...Details
Measuring Carbon and Sulfur in Electronic Components232023 AprWith life becoming increasingly digital and smart, various electronic products, such as computers, mobile phones, and a wide range of AI smart products, have permeated all aspects of our lives. These ...Details
Elemental Detection in Lithium Battery Materials162021 NovBattery ComponentsCathode Material: This is a layered or spinel-structured transition metal oxide or polyanionic compound with a high electrode potential and stable structure that can intercalate lith...Details
The Effects of Various Chemical Elements on Steel Properties112021 JunCarbon (C)Carbon is the main element after iron, and it directly affects the strength, plasticity, toughness, and weldability of steel.When the carbon content in steel is below 0.8%, increasing the ca...Details
How to Choose Laboratory Countertops272019 NovTo date, laboratory countertops are a very prominent and frequently used and important component in most laboratories. Since the late 1980s, when epoxy resin gradually replaced cement asbestos as the ...Details
Properties of Carbon and Sulfur in Carbon-Sulfur Analysis072019 AugIn the current context of declining steel industry production capacity and market demand, expanding the analytical range of carbon-sulfur analyzers to accommodate the diverse needs of analyzing specia...Details
