Description

Horizontal type sample preparation and briquetting equipment

Technical Field

The invention relates to a horizontal sample-making briquetting device, which presses powder or granules into regular sample blocks with smooth and flat surfaces.

Background

With the development of science and technology, the novel spectrum analyzer is highly regarded by the detection field, is widely applied to the metal detection field at present, and accurately displays the measurement result in real time for the measurement of metal element components and element content. The method has a small application range in the non-metal field, the spectral analysis instrument has strict requirements on the surface of a detected substance, and the smoother and smoother the surface of the detected substance, the more accurate the detection data. Therefore, the application of the spectrum analyzer in non-material detection is important for making a uniform standard sample block for the detected material.

The spectrum analyzer is based on the principle that the characteristic spectrum of an element to be measured, which is emitted from a light source, is absorbed by ground state atoms of the element to be measured in vapor of a sample, and the emission spectrum is attenuated, thereby determining the content of the element to be measured in the sample, which conforms to the lambert-beer law a = -lg I/I o = -L gT = KC L, where I is the transmitted light intensity, I0 is the emitted light intensity, T is the transmittance, and L is the optical path length L of the atomizer, so that the atoms of any element are composed of nuclei and electrons moving around the nuclei, and the electrons outside the nuclei are distributed in different levels according to the high and low levels of their energies, so that one nucleus may have multiple energy level states.

Emission spectrum analysis process:

1. the sample is vaporized and atomized (converted into gaseous atoms) under the action of energy, and the outer electrons of the gaseous atoms are excited to a high energy state. When transitioning from a higher energy level to a lower energy level, the atoms will release excess energy and emit characteristic lines. This process, known as evaporation, atomization and excitation, is achieved by means of an excitation light source.

2. The radiation generated by atoms is dispersed and split, and recorded on the light-sensitive plate according to the wavelength sequence, so that regular spectral lines, namely a spectrogram can be presented. Is realized by means of a light splitting and detecting device of a spectrograph.

3. And carrying out qualitative identification or quantitative analysis according to the obtained spectrogram. Because the atomic structures of different elements are different, the wavelengths of the emitted light lines are different after being excited, namely, each element has the characteristic wavelength, so that the existence of the elements can be accurately identified according to the characteristic spectrums of the elements (qualitative analysis), and the intensities of the spectral lines are related to the content of the elements in a sample, so that the content of the elements can be determined by using the intensities of the spectral lines (quantitative analysis).

Advantages of the spectroscopic analyzer:

1. the sampling mode is flexible, and the loss caused by sampling can be saved for the detection and analysis of rare and precious metals.

2. The test speed is high, multi-channel instant multi-point acquisition can be set, and real-time output is realized through a calculator.

3. The nondestructive testing can be carried out on some mechanical parts without damaging samples, and the nondestructive testing is convenient.

4. The analysis speed is fast, and the method is more suitable for stokehold analysis or field analysis, thereby achieving fast detection.

5. The accuracy of the analysis results is based on the chemical analysis standards.
