Let’s talk about which domestic chromatography company is the best?

Our factory uses Sichuan Instruments, and they have good sensitivity and stability, but they tend to make small mistakes. I have also used Beifen, which is relatively expensive and has many problems.
When it comes to performance, I still have to point out that instruments at different prices are different. The stability of domestic products still needs to be improved, such as Fuli and Kejie.
I also want to know more about it. There are too many domestic brands, and they vary from good to bad.
In fact, when judging the product performance of an instrument manufacturer, it is best not to judge it in simple terms such as good or bad. For an analytical instrument, especially an analytical instrument with many applications, my criterion for judging is that if the instrument manufacturing company has a complete R&D department and this department can have technical personnel as the backbone, then the company's products will not be bad, but the price may not be particularly favorable. If this analytical instrument company is a manufacturing company that mainly relies on assembly or assembling, and its research and development is in name only or does not exist at all, then this company's instruments will not be much better, but the price will be very satisfactory to some companies who want to use the instruments.
:D very much agree with your point of view.
I have used Fuli's instrument. I am still using that instrument now, more than ten years ago. It's pretty good.
The high-purity argon chromatography DHP-06 used by our company from Dalian Kona Institute of Physics and Chemistry is extremely unstable. Moreover, it cannot be analyzed below 0.8ppm, and the baseline changes too much. I have communicated with Liuzhou Iron and Steel Co., Ltd. and other companies, but they are all useless. 1. The sensitivity is no more than 2. It is extremely unstable.
