Please recommend the gas phase brand, which brand is more cost-effective
We use the domestic Shandong Luneng SP501, 502, 2000. They feel good, cheap and practical.
There is no comparison. Just like wearing clothes, there are specialty stores, street stalls, shopping malls, and shopping malls. You have to choose according to your specific situation. If the analysis requirements are particularly high, you can choose imported ones such as Shimadzu and HP. If the requirements are not too strict, generally domestic ones can handle it.
When you have high requirements for scientific research or analysis, buy imported ones, such as Agilent, Varian, etc. Do not buy Japanese instruments that are designed for a few years. After a few years, you will have to scrap them, otherwise your maintenance costs will be very high. If the requirements are not high for ordinary use, just use domestic ones that are cheaper.
I feel Agilent's is better, but Shimadzu's after-sales service is terrible.
We used fifteen Shimadzu GC-2014Cs and it didn’t feel very good.
Agilent and Shimadzu are okay, but the price is too high. How about domestic brands?
For general gas chromatography analysis, domestically produced gas chromatographs can meet the requirements. We have two gas chromatographs at home, and we conduct test analysis for customers. The results are generally similar, and the customers are very satisfied.
I have used Agilent and Varian. Based on my personal usage of these two brands, I prefer Agilent. Simple and convenient.
We have both Shimadzu and Agilent. When buying products from these two companies, you have to choose the right model.
We use Agilent for foreign products, and Beifen for domestic products!
Depending on the sample you want to analyze, my unit uses Agilent, Dongxi Electronics
