Rough classification of gas chromatograph users

Different types of GC users have quite different analysis purposes and requirements. Therefore, the functions, performance, and operating characteristics of the same type of equipment are also very different. As a new customer, you first locate yourself in that level category. It is also one of the main factors for choosing a good instrument. We divide GC users into three categories: 1. National research institutes and different types of GC users have quite different analysis purposes and requirements. Therefore, the functions, performance, and operating characteristics of the same type of equipment are also very different. As a new customer, you first locate yourself in that level category. It is also one of the main factors for choosing a good instrument. We can roughly divide GC users into three categories: 1. National scientific research institutes and research departments in colleges and universities: mainly used for life sciences, environmental sciences, new materials science, forensic science, military science, aerospace science, archaeological research, agriculture, forestry, geology and oceanography, pharmacodynamics and toxicology Analysis and testing methods such as research. 2. National ministries, bureaus, head offices, key industries in the national economy, research institutes, analysis centers, testing centers, monitoring centers set up by large enterprises, etc.: For example, typical industries are: chemical industry, petroleum industry, metallurgical industry, energy ( Nuclear energy, coal) industry, semiconductor industry, machinery industry, pharmaceutical industry, light industry (food, daily chemical), commerce, construction, etc. 3. Customers used for first-line analysis such as: process control and quality assurance in the production process of factories, quality supervision of import and export commodities, disease diagnosis, health and epidemic prevention, industrial hygiene investigation and evaluation, public security investigation and evidence collection, military equipment related monitoring (military Environment such as: missile launch site, submarine air quality monitoring), biological product analysis, daily environmental monitoring analysis, resource development site analysis (oil field, natural gas calorific value calculation), daily commodities (cosmetics, fragrance composition, glass, ceramics, paper industry) Etc.) Quality monitoring, decoration material quality monitoring, teaching laboratories, etc.
