What are the uses of chromatographs? There are many uses for chromatographs Waters HPLC vials china manufacturer. After many years of development, chromatographs play a particularly important role in all areas of our lives. Chromatographs are generally divided into gas chromatographs and liquid chromatographs. Can be widely used in pharmaceutical, petroleum, chemical, environmental protection, food, materials science, *, national defense and other fields, is a powerful tool for laboratory research and routine application analysis, is an indispensable analytical test instrument for scientific research and production. So, what do you need to pay attention to when checking the chromatograph?
Whether it is a gas chromatograph or a liquid chromatograph, baseline noise, baseline drift, and small detection concentration of zui are important indicators of three Zui, and their verification can be carried out using only standard substances.
2. The instrument has many models and complicated operation.
Before the chromatograph is operated, it is necessary to change the column, mobile phase, start the pump and detector, and set the attenuation, flow rate, paper speed, etc., so the operation is more complicated. In addition, there are many models of chromatographs, and the operating interfaces of various types of chromatographs are different, especially the introduction of computer workstations, which makes the operation of various types of chromatographs more different.
3. Long verification time
It takes 3-5 hours to verify a chromatograph, which takes a long time Waters HPLC vials china manufacturer. The chromatograph should be preheated for 1-2 hours before running, otherwise the baseline of the instrument is difficult to stabilize. In addition, both the baseline and repetitive tests take longer during the verification process.
This is the end of the introduction of Where the chromatograph needs to be noted. I hope it can help you.
