Rapid analysis of alloy metal elements

合金金属元素快速分析OES8000S

Working Principle:

Atoms or ions can exist in discontinuous energy states, which can be described by spectral terms; When an atom or ion in the ground state absorbs a certain amount of external energy, its extranuclear electrons transition from the ground state to the excited state. However, an atom or ion in the excited state is very unstable and undergoes a process of approximatelyJumping back to the ground state in seconds and releasing the energy absorbed by excitation in the form of light, arranging these lights in a certain wavelength order is called atomic spectrum; Due to the fact that specific elements can generate a range of different wavelengths of light, qualitative analysis can be carried out by identifying the presence or absence of characteristic spectra of the tested element, and quantitative analysis can be performed based on the intensity of light at that wavelength.During the excitation process, electric sparks are generated between the electrodes in the excitation station and the pre prepared metal sample. The light emitted by the spark enters the light chamber through the incident slit, and after being separated by a grating, the light of different wavelengths is split at different angles and irradiated onto the CMOS sensor. Sensors convert optical signals into electrical signals and transmit them to computers through measurement systems. After processing, analysis results are obtained.

Configuring and supplementing testing substrates, channels, and analysis programs is extremely convenient, making it easy to supplement testing elements and analysis programs at the customer's location after delivery.

Suppliers provide core components

Spectral dispersion element grating from GermanyZeiss/FranceYYMade by the company to ensure excellent spectral resolution capability

Spectral detectorCMOSThe detector is manufactured by Hamamatsu, Japan, ensuring sensitive and low-noise spectral line detection

Light room constant temperature system

The constant temperature chamber of the light room is equipped with a feedback heating device and a temperature insulation layer, effectively ensuring constant temperature inside the light room.

This suppresses the optical path drift caused by slight changes in the size of mechanical components under temperature fluctuations. Except for special maintenance, regular maintenance generally does not require tracing.

Simultaneously operating the detector in a constant temperature environment helps to stabilize the photoelectric conversion performance.

Quickly and simultaneously analyze multiple elements in steel and non-ferrous metal materials

After placing the pre processed sample on the sample stage,OES8000sCan be at most40Present test results within seconds.

We can test the content of common elements in almost all steel and non-ferrous metal materials according to customer needs.

Professional testing plan

With the accumulation of long-term testing technology services, Tianrui Instrument provides mature testing solutions for steel and non-ferrous metal material analysis users.

The testing plan adopts an analysis program that classifies the content of material elements to meet various common testing needs of users.

The analysis program is calibrated by the original factory using international and national standard samples, and fitted and calibrated by professional instrument software.

Users only need to use a small number of standardized samples from the original factory configuration to complete daily maintenance, without the need to purchase a large number of standard samples for making analysis programs.
