Furthermore, since chromatography analyzers involve knowledge of chromatographic analysis theories, applications, sample preparation, data processing, and even specialized skills related to chromatography columns, it is also necessary to have a good understanding of professional materials on chromatography. As a reference, the Analytical Chemistry Handbook (published by Science Press) has a dedicated volume on chromatography. There is a great deal of specialized literature on gas and liquid chromatography. Also, write the character for \"phase\" in gas chromatography correctly.
Different models of chromatographs have different operating methods. For existing chromatographs, it is first necessary to understand their working principle and read the operation manual carefully. Referring to our gas chromatograph, I have summarized the following points to note: 1. Different chromatography columns have different maximum operating temperatures; when setting the temperature, it must not exceed the maximum operating temperature of the column ； 2. Chromatography columns are divided into polar and non-polar columns; pay attention to distinguishing the media suitable for each type ； 3. Chromatography columns that are used frequently should be aged regularly, following the aging procedures specified in the instructions ； 4. Different tests may require different carrier gases; be sure to choose the appropriate one.
