Description
Technical Field
The invention relates to the field of detection equipment, in particular to a quick-drying finely-grinding adhesive for laser ablation sample target preparation.
Background
The laser in-situ analysis technology (including LIBS and LA-ICP-MS) is a technology capable of realizing in-situ sampling of a micron region, and the laser ablation is combined with the spectrum or the plasma mass spectrum to analyze the content of main trace elements or the composition of isotopes of a sample. In recent years, the technology is widely applied to the fields of earth science, modern science and technology, archaeology, material science, life science and the like.
The laser in-situ analysis technology focuses laser on a sample surface to be ablated through a light path, plasma generated by ablation is analyzed to obtain an LIBS (laser induced breakdown spectroscopy) spectrum signal, aerosol generated by ablation is analyzed by mass spectrometry to obtain an ion signal, and the ion signal and the aerosol can be complemented with each other to obtain the content of main trace elements or isotope composition so as to research element distribution rules or isotope tracing, marking and the like. The laser ablation inductively coupled plasma mass spectrometry is one of the most effective technologies for carrying out in-situ micro-area analysis on main trace elements and isotopes on a solid sample, and the technology is widely applied to the fields of geology, materials science, biology, chemistry, archaeology and the like. Has become the mainstream conventional mineral micro-area element and isotope analysis instrument.
In the laser ablation plasma mass spectrometry, a sample to be detected is firstly placed in a target seat, then the target seat is placed in a laser ablation pool, and sample aerosol generated on the surface of the laser ablation sample is carried into the plasma mass spectrometry by carrier gas to carry out element and isotope analysis.
In geological exploration, online monitoring and other industrial activities, a large amount of powder samples are often required to be analyzed, but the direct detection of the powder samples has great defects. The reason is that laser can generate shock waves in the process of hitting a sample, mechanical vibration is caused, a powder sample splashes, an instrument is polluted, and detection is interfered, so that LIBS detection is usually carried out after the powder sample is subjected to tabletting treatment, and result interference caused by powder splashing is avoided. However, when tabletting powder samples, not all samples can be directly tabletted, and usually a certain solid binder is added for mixed tabletting. The binder used for tableting may be inorganic compounds such as silver, aluminum and potassium bromide, and organic substances such as polyethylene and polyvinyl alcohol. The metal elements contained in the inorganic compound adhesive greatly interfere spectral signals, and the adhesive has certain influence on detection results. Although the organic adhesive only contains elements such as carbon, hydrogen, oxygen and the like, and has little interference on the detection of sample elements, the organic adhesive in the form of solid powder is mixed with a sample, ground and tabletted, and has a space effect, so that the particles are loosely arranged, a strong adhesive force cannot be formed to maintain the form of the sample, and the mechanical property of the obtained sample is poor. Meanwhile, the adhesion between the organic binder and the sample particles is weak, which results in that the solidified sample is greatly influenced by other factors, such as the size difference of the sample particles in the mechanical mixing process can cause the longitudinal distribution of the sample particles in the organic binder to be uneven.
