Is it better to equip the laboratory with ICP or X-fluorescence?

X-fluorescence spectroscopy, to be honest, Japan's Shimadzu, Rigaku, etc. are all good, but I recommend using domestic ones or other imported brands. Because we must be patriotic and support domestic products! Start with me

I asked two classmates and they all used imported ones, either from the United States or Japan. There are domestically produced ones, but they didn’t dare to use them.

This phenomenon does exist, and the main reason is the limitation of technical level. It all depends on the working conditions, choose according to the actual situation!

Can you explain the following question?: 1. When the Chinese anti-Japanese army attacked the Japanese invaders, was it more effective to use the captured Japanese 38 guns, or was it more effective to use the old rifles and swords renovated from the border areas? 2. In the analysis and inspection work of actual production, is it better to use imported products that are stable and reliable and have few daily failures, or to use domestic products that are not very reliable and have high daily failure rates? Excluding domestic products and imported products, the quality and performance are very reliable. When discussing technology, the premise is to improve production efficiency and ensure process operation. It seems quite childish and ridiculous to talk about patriotism.

Regarding the landlord's problem, several aspects should be considered. 1. ICP atomic spectroscopy analysis and X-ray fluorescence analysis are two different analysis methods. There are certain differences in sensitivity, accuracy, daily maintenance, etc. This should be considered from the specific analysis indicators of the sample and the technical level of the laboratory personnel's application and operation of the analyzer. 2. ICP analyzer has better analysis effect on light elements, while X-ray fluorescence analysis is more suitable for heavier elements. For specific analysis, which ocher element is the main one? 3. X-ray fluorescence analyzer is an instrument for radiation equipment management, and its operation and maintenance requires relatively high technical background of personnel. ； The ICP atomic spectrometer is a more general analytical instrument, and the analysis method is relatively mature, and the technical background requirements for the operator are not particularly high. 4. The X-ray fluorescence analyzer has no special requirements for the sample form and composition, and has good adaptability to liquid and solid samples, and the daily chemical consumption is also very low ； ICP atomic spectrometer analyzers generally perform appropriate or special processing of samples. The analyzer requires some fixed consumption and regular maintenance consumption. The author has a better understanding of his own company's situation, and can determine which instrument should be chosen by visiting laboratories and quality inspection offices of similar companies.

Now and then, I see you are a loyal person! Everything you do is selective! During the Anti-Japanese War, they were captured and forced. We obtained them through struggle and bloodshed and sacrifice. But now, we have to take the initiative to use so much money to buy the equipment of a nation that has brought indelible nightmares to our people, so that they can have more money to build more weapons to fight against us! ? If every Chinese can change this idea of ​​worshiping foreigners and favoring foreigners, support domestic production, support * * With the advancement of technology, maybe we already have better brands! look at someone * * , can write such despicable things into textbooks, yet some of us are still insensitive! We support scientific progress and we must learn * Good technology, but not transplanted equipment, the technology must also be transplanted, this is the fundamental! Their technology is good, but let’s think about it, how do they achieve their technological progress? So have you forgotten all the cruel experiments on human bodies? This shouldn’t be said on the forum, but I think this is a lack of education! I hope to remember that the rise and fall of a nation is the responsibility of every man!

Still continuing to learn* Thank you in advance for sending a lot of information from various instrument manufacturers. I feel that what users say is more effective.

We are direct users, and personally feel that it is more practical. If something goes wrong every three days, things are not done well, and the problem cannot be solved, it may affect the efficiency of the factory and everyone's income. Patriotism is a political issue, an ideological issue, not a matter of whether to use advanced technology. If domestic products and imported products are at the same level, domestic products must be used. If nothing else, after-sales service and communication will definitely be more convenient and faster.

China is still in a backward stage in many places, which has a lot to do with the fact that there are a large number of patriots in China who can only shout patriotic slogans. I suggest you read some articles by Wei Yuan and Yan Fu before shouting such patriotic clichés.

You are right, you understand the truth, and there must be comparisons in all aspects! We also affirm foreign technology, but we cannot completely deny domestic brands! In this regard, it’s not just one person’s decision, it needs to be weighed comprehensively! We bought several imported machines in the past, but because the contract did not clearly state some parameters and technical requirements, several machines worth tens of millions of dollars in total could not be used normally after arrival. We were very good at what we said before signing the contract. It was nonsense to say that we would arrive at the factory within 24 hours to solve the problem. Even if the problem could not be solved, it would cost thousands, and it would take extra time to adjust the parameters or configuration of the equipment! Therefore, you must be clear when buying this kind of equipment! Otherwise, follow-up questions will continue!
