Advantages of Argon Purifier in Direct Reading Spectrometer

The spark direct reading spectrometer is an instrument for rapid elemental analysis in front of the smelting furnace, which is one of the effective means to control the quality of metallurgical products, and is widely used in metallurgy, mechanical processing, material research and other fields. Spark direct-reading spectrometer is a kind of atomic emission spectrometer, which requires high purity of argon used in the working process. If stable and high purity argon can not be obtained, there will be many problems in the use of the instrument, such as: the correction factor exceeds the required range, the standardization factor is too high; Excitation light source discharge is not normal; When excited, diffusion discharge, ionization effect is poor; The lens is easily contaminated by impurities in the argon gas. The analytical data is not stable, especially for the analysis of carbon, phosphorus, sulfur, silicon and other elements; The abnormal proportion of single discharge increases, which can not meet the requirements of high-precision analysis. The use of argon purifier produced by Yian SAIDI can improve the purity of argon and effectively solve the problems in the process of using direct-reading spectrometer.

Advantages of argon purification machine in the use of direct reading spectrometer:

The output of stable and high-purity argon can effectively protect the optical lens of the direct-reading spectrometer, minimize the possibility of optical lens pollution, effectively reduce the loss of spectrum, and improve the precision of data.

The excitation light source is provided with high purity argon, and the diffusive discharge of the excitation light source is prevented. The utility model has the advantages that the excitation light source is more reliable and stable, the excitation light source is effectively protected, and the service life and the reliability of the direct-reading spectrometer are improved.

The excitation efficiency of samples (such as ball-milled cast iron, high-silicon aluminum alloy, etc.) is improved, the possibility of oxidation of analytical samples is reduced, and the sensitivity of ultraviolet (short wavelength) elemental analysis is improved.

Provide a high-quality argon gas source (that is, argon with a content ≥ 99.999%) to the direct-reading spectrometer, so that the accuracy of the analysis value of the direct-reading spectrometer is guaranteed. Especially for the analysis of special elements, such as N (nitrogen), if the purity of argon is less than 99.9999%, it will affect the analysis result of nitrogen.

Economic accounting: Taking the application of high-purity argon purifiers in direct-reading spectroscopic instruments as an example, the largest consumable in the use of direct-reading spectrometers is argon, The use of high-purity argon purifiers can replace 99.999% high-purity argon or liquid argon at a market price of about 300 yuan / bottle with 99.9% or 99.99% ordinary pure argon at a low market price of about 120 yuan / bottle. The purity of argon (99.999% -99.9999%) required by direct-reading spectrometer can be achieved by Yian SAIDI purifier. The spectrometer works for 8 hours a day (3 days for 1 bottle of argon), and is turned on 350 days a year. According to the use of a direct-reading spectrometer for 10 years, the high-purity argon purifier will save users a considerable amount of money.

Solve in the use of cylinder argon encountered in the process of purity, procurement, transportation, storage and many other issues.

Characteristics of High Purity Argon and Common Argon Purification Related Argon Purifier

1, the catalyst activity is high, the working temperature is low, using bottled pure argon can be purified by the machine to obtain high purity argon, which can reduce the cost for users.

2, double structure, one group of work another group of regeneration standby, it can be long-term continuous gas supply.

3.Adopting the regeneration process of pure gas purging of the machine, the regeneration does not use hydrogen, so it does not need a special machine room, and the safety is good.

4 、 Using LCD touch screen, the pressure and temperature can be detected on line through the sensor on the touch screen. The working and regeneration cycle of the system can be adjusted according to the actual usage of users, which is beneficial to save the gas source.

5, humanized design: small size, light weight, energy saving and environmental protection, easy to install and operate;

6, technological innovation: the use of imported high-end adsorption technology, the core components using high-tech synthesis reactor, replacing the traditional tower structure. Higher purification purity, which is another breakthrough in argon purification technology;

7, purification method: nitrogen removal effect is excellent, the use of solid filtration and chemical catalytic reaction and other multi-stage purification combination of synthetic reactors, argon purification purity can reach 99.9999% (nitrogen content ≤ 0.1ppm);

8, purification filtration: argon input and output end are installed gas powder filter (filter powder diameter < 0.3 μ m);

9 、 High quality fittings: adopt high quality imported stainless steel pipe and valve (both inside and outside electropolishing), ensure high purity argon output use;

10, can be used with various brands of spectral instruments at home and abroad;

11, electrical components are subject to long-term aging test to ensure the reliability of the instrument.

12, work, regeneration has automatic switching function, no manual operation, performance is more stable and reliable, to avoid user misuse to the system caused by pollution.
