With the growing demand for metal materials in various industries, some complex materials have emerged. The composition of metals is the main factor that determines the materials. The compositional analysis and detection methods for metallic materials have been continuously developed, and traditional titration and spectrophotometry have been continuously developed to new types of detection methods. For example, infrared absorption method, spark direct reading spectrometry, etc., are detected by traditional single elements and can now be detected. Simultaneous detection of multiple elements increases the efficiency and accuracy. Nanjing Kirin detection instrument high-frequency infrared carbon sulfur analyzer, spark direct reading spectrometer can be applied to the composition of metal material detection. By analyzing the composition of the metal material, you can understand the composition of the material and monitor the quality of the product in order to better apply the material to the product.
High Frequency Infrared Carbon and Sulfur Meter at Customer Test Center
Among metal materials, especially steels, carbon and sulfur are the main elements of detection. However, traditional methods cannot accurately quantify carbon and sulfur. Therefore, carbon and sulfur elements need to be detected by Nanjing Kirin high-frequency infrared carbon-sulfur instrument using infrared absorption method. The carbon and sulfur in the sample are heated at high temperatures under oxygen-enriched conditions and oxidized to carbon dioxide and sulfur dioxide gas. After the gas is processed into the corresponding absorption tank, the corresponding infrared radiation is absorbed and transmitted by the detector as a signal, and the output is processed by a computer. This method is accurate, rapid, and highly sensitive. Both high and low carbon and sulfur content can be used.
Spark Direct Reading Spectrometer at Customer Testing Center
Spark direct reading spectrometer uses the high temperature of the arc (or spark) to make each element of the sample directly evaporated from the solid state and is excited to emit the characteristic wavelength of each element. After being separated by a grating, it becomes a "spectrum" arranged according to wavelengths. The characteristic spectral lines of the elements pass through the exit slits and enter the respective photomultiplier tubes, and the optical signals become electrical signals. The instrument's control and measurement system integrates the electrical signals and performs analog-to-digital conversion, and then it is processed by a computer to detect each The percentage of the element. The method has high accuracy and can carry out multi-element simultaneous analysis. At the same time, it can obtain the qualitative and quantitative analysis results of dozens of elements in a single excitation and analysis. It is simple and easy to analyze, and it can analyze the content of dozens of elements of alloy steel or non-ferrous alloy in 20 seconds in real time. Does not consume expensive chemical reagents or special excipients. Solid samples can be tested directly. The disadvantage is that there is a certain requirement on the shape and size of the sample.
