How much does a domestic direct emission spectrum analyzer cost?

It is generally divided into imported and domestic, and is made in the marketSpectrometer

The ** is generally about 150,000, while the imported ** is slightly more expensive than the domestic spectrum analyzer because of tariffs and multi-layer dealer wholesale and retail, and the market price is generally in the range of 20-1 million. But there are still many companies willing to spend a lot of money on procurement, why is this?

This is more due to the late research and development of the domestic desktop spectrometer detection field, and there is a certain gap between the technology and foreign countries. For example, some companies with high-quality requirements for materials have high requirements for the accuracy of spectrometers used to detect quality, so they naturally have to purchase foreign spectrometers, and would rather spend more on them. But did you know?

With the construction of the integration of the world, there are already better options.

In order to better understand, before answering, you need to understand the detection principle of the spectrum analyzer, the use of different metals have different refractive light, through the grating for light splitting, the analysis of the spectrum can detect the element content, the imported spectrum analyzer detection accuracy is the grating is good, and because the production of grating such a good brand, most of them are abroad, such as the 5th generation of spectrum analyzer used in the German Zeiss grating, Zeiss company has a long history in the field of optics, founded in World War II, It is a top company in the field of optics. The high-quality encoders produced by it have the following points:1

High transparency, no impurities block the light through. 2.Effective light transmission and light splitting, so that the light is effectively refracted

3.The raster is precisely aligned when focused.

The question of how much is a domestic direct reading spectrometer depends on the specific configuration.

Optical emission spectrometer is a class of high-precision spectrometers that can measure the composition, structure, and properties of substances. The following are some of the well-known foreign manufacturers of direct reading spectrometers:1

Constanticom, France (Conad): Constanticom is a long-established instrument manufacturer whose optical emission spectrometers are widely used in chemistry, analytical science, environmental science, and more. 2.

Pfizer (Pierce): Pfizer is a leading global manufacturer of laboratory instruments, and its optical emission spectrometers are widely used in chemical, petroleum, biological, environmental and other fields. 3.

Edwin Cook: Adcock is a company focusing on the manufacture of analytical instruments, and its direct emission spectrometers are widely used in chemistry, petroleum, biology, environment and other fields. 4.

Elie-IHA: For more than 150 years, Elivet is a manufacturer of calibration instruments that are used in chemistry, analytical science, environmental science, and more. 5.

Siemens: Pony is the world's leading manufacturer of laboratory instruments, and its optical emission spectrometers are widely used in chemical, petroleum, biological, environmental and other fields. 6.

Okade, Japan: Okade is a manufacturer of calibration instruments for more than 40 years, and its optical emission spectrometers are widely used in chemistry, analytical science, environmental science, and other fields. The above are some well-known foreign manufacturers of direct emission spectrometers, which have the characteristics of high precision and high stability, which can meet the needs of laboratories in different fields.

First, the brand of direct reading spectrometer:

If the various brands of direct reading spectrometer are compared, they can be divided into imported products and domestic products;

Imported brands can be divided into several echelons: first-class: German OBLF, Swiss ARL (now acquired by Thermo of the United States); Second-rate:

German SPECTRO, Bruker, etc.; Third-rate: Oxford spectrometer in Germany, GNR in Switzerland, Shimadzu in Japan, etc.; (Purely personal opinion, don't spray if you don't like it).

Some domestic instruments are basically equivalent to imported second-rate; The main brands that have been doing it for more than ten years are: Steel Research Institute Nack (CCD full-spectrum direct reading PMT photomultiplier tube type), Yantai Dongyi (PMT photomultiplier tube type), the direct reading spectrometers of these two manufacturers are relatively reliable; As for the domestic equipment of other small manufacturers, it is not recommended to consider, the service life of the direct reading spectrometer is about 10 years, and the stability of the lack of technical strength is very problematic.

The metal detection industry is familiar with the National Iron and Steel Materials Testing Center and the Iron and Steel Research Institute Nanogram Instrument is a company, before the first imported equipment comes with maintenance, and then self-developed to make a leading generation of domestic direct reading spectrometer.

[Spectrum with Boyue 30 seconds = 18 elements].

Purchasing a direct reading spectrometer is like buying clothes, everyone thinks that the quality of the spectrometer with the direct reading spectrometer brand will be better, but there are a variety of direct reading spectrometer brands on the market, and everyone is a little at a loss in the face of these brands.

When you choose, you will first start with the brand from the quality aspect, so how to look at the quality? You can see the sensor inside the optical emission spectrum analyzer and the quality of the grating, which control the detection range and detection accuracy of the spectrometer, respectively. In this way, the purchased spectrometer is more suitable for the needs of the enterprise in actual use.

Then it is to look at the strength of the manufacturer, to see if it has its own factory and staff, the more people indicate that it has more strength, to go to such a manufacturer to purchase their own heart, do not have to worry about the purchase of direct reading spectrometer, after the later use of the problem can not find someone to be responsible for the problem.

There is no list of the top 10 brands, everyone is swiping tickets, anyway, the first direct reading spectrometer is made abroad, but this takes into account the cost, as well as maintenance, and the bottom is also a foreign brand.

There are many brands of direct reading spectrometers, and it is not clear who is who! Technology is constantly changing, and brand management is changing over time. So take a look for yourself, from the inside of the machine to the appearance of the machine, you can reflect the strengths and weaknesses of the brand.

There is never the best, only the most suitable brand and service.

Those who have used ARL are still relatively stable.

The spectrometer is a simple and fast metal composition detection instrument. Using the analytical principle of atomic emission spectroscopy, the optimal spectral range of each element can be measured by photomultiplier tubes, but the market has been upgraded from photomultiplier tubes to CMOS sensors. There are many manufacturers of direct emission spectrometer, and to choose a reliable manufacturer, you can choose from the following aspects.

1. Technical parameters.

Direct reading spectrometers are mainly used in casting, steel, metal and smelting, as well as military industry, aerospace, electric power, chemical industry, colleges and universities and other units. The parameters of the spectrometer are determined by the dispersion component, and the selection of the dispersive component is a key issue in the design of the imaging spectrometer, and the advantages and disadvantages of the prism and grating dispersion components should be comprehensively weighed. A reliable manufacturer will customize the parameters according to the needs, which has made it more cost-effective.

2. Functional use.

Optical emission spectrometer is a rapid quantitative analysis instrument for the analysis of ferrous and non-ferrous metal composition. It can be used for a variety of matrix analysis, AL, PB, MG, ZN, SN, FE, CO, NI, TI, CU, etc., a total of more than 50 elements. When choosing a direct emission spectrometer, you should first clarify what the purpose of purchase is, and then purchase it according to your own needs, you can consult the manufacturer about the advantages and disadvantages of different optical spectrum analyzers and the scope of use, so as to obtain more detailed information.

3. Manufacturer qualification.

In addition to the technical certificate, the manufacturer of the direct reading spectrometer should also have the provincial approval of the "People's Republic of China Measuring Instrument Type Approval Certificate", which means that it is a regular production enterprise, with reasonable property rights, and it is worth reassuring in the process of use.

4. After-sales service of the manufacturer.

The service ability after the purchase is also quite important, regardless of the distance can be arranged to install and debug personnel within the specified time to provide door-to-door service, problems have a team of engineers to solve in a timely manner, rather than two or three days no one cares.

In fact, our company bought a domestic spectrometer called Gangyan Nack, which has been used for almost two years, and the frequency of use is quite high, and there is no problem with the instrument. When we started to choose, we were also worried that the domestic production was not good, I had a friend who also bought a foreign brand, and it was not so unpleasant to use, and it would take a long time to report for repair, so I wanted to buy a domestic one. Personally, I don't have any objections to foreign brands, but I think it's good to use domestic ones, and I just have some feelings.

Upstairs is very pertinent, but also more professional, the import is also divided into good and bad, the budget is enough, try to be Spike, ARL, OBLF three choices.

It's still a good point to import, and if you want to save money, you can buy the right domestic one.

1 If you have money, you must buy imports, try to find a manufacturer or a first-class **2 curve, don't have to match too completely, just use it.

3 Iron and steel industry c s to a special carbon and sulfur meter will be more accurate and cost-effective 4 A small number of special grades of metal is really not easy to do, you can use the chemical method do not have to force direct reading of the spectrum to do 5 do not underestimate personnel training and pre-treatment.

6. Spectroscopic instruments, laboratories, temperature, humidity, vibration, voltage fluctuations, and ground wires must be done in strict accordance with the requirements.

Think of that first.

In the market of direct reading spectrometer, there are distribution, second-hand, leasing and factory direct sales.

The first point is the brand's innovation ability, have there been new products in recent years, and which ones have been produced?

The second point, technology, spectroscopy technology is the first one discovered and manufactured by foreign researchers, and the domestic instrument has changed its ** from more than one million to more than 100,000, and the domestic equipment is cheap, and many core technologies and components are inseparable from foreign components, which can only be replaced slowly.

The third point is the technical ability, the certification and honor of the research and development application, how many patented technologies, and each brand has a brand characteristic.

Fourth, customer case, which manufacturers have bought this brand of equipment, if there are manufacturers you know, you can also try it, and then consider, the brand does not mean that the product is good, and it is right to buy what you want.

Fifth, service, many times is not a bad product, but poor service, if because of the company's personnel turnover, the replacement of personnel can not operate the instrument, retraining is difficult, a good service attitude can also be obtained from the purchased manufacturers, it can be seen that a good and pertinent evaluation is very important.
