Mixed standard sample of Baijiu Standard sample of Baijiu chromatograph

liquor

Baijiu is a kind of special commodity. Its particularity is not only that it is a kind of food and must meet the requirements of its corresponding product standards, but also because it has its own characteristics. For example, Baijiu is composed of more than 200 kinds of flavor components, but its content is very small, and the low content is only a few parts per million. Some trace components are difficult to determine even with current analytical instruments, but those trace components play a very important role in the formation of Baijiu style.

Mixed standard sample of Baijiu Standard sample of 23 components Standard sample of Baijiu chromatographComponents:

There are 13, 15, 16, 22, 30 and 46 standard solutions for Baijiu. Various component mixed standard solutions can be configured according to user needs, including 13, 15, 16, 22, 30, 46 parameter standard solutions

Mixed standard sample of Baijiu Standard sample of Baijiu chromatographPerformance characteristics:
