1. What is VOC?

VOC substances are volatile organic substances. VOC is the abbreviation of volatile organic compounds. In general, VOC is the command of organic compounds; but in the sense of environmental protection, VOC is defined as a kind of active volatile organic compound, that is, the type of volatile organic compound that will cause harm. VOC can be divided into two categories:

One is the general definition of VOC, which only describes what is VOC or under what conditions it is VOC. The other is the definition of environmental protection, that is, the kind of volatile organic compounds that are active and harmful that needs to be detected by a VOC measurement device. Volatilization and participation in photochemistry are very important in the sense of environmental protection. Without volatilization or participation in atmospheric photochemistry, no harm will be caused. There are VOC monitoring instruments that are specialized in volatile organic compounds.

2. What is VOCS?

In China, VOCs (volatile organic compounds) are volatile organic compounds. It refers to the organic compounds with saturated vapor pressure greater than 70 Pa at room temperature, a boiling point below 260 C at atmospheric pressure, or all organic compounds with relative volatility greater than or equal to 10 Pa at 20 C. From the point of view of environmental monitoring, it refers to the non-methane total hydrocarbons detected by hydrogen flame ion detector. Generally speaking, it mainly includes alkanes, aromatics, olefins, halogens, esters, aldehydes, ketones, and other organic compounds. By checking the VOC monitoring system, you would note that VOC and VOCS are the same kind of substances, that is, the abbreviation of Volatile Organic Compounds (VOCs). VOCS is more precise because there is more than one general component of VOCs.

3. What is TVOC?

TVOC and VOC are the relationships between inclusion and inclusion. Various measured VOCs are collectively called total volatile organic compounds (TVOC). So that TVOC includes VOC.

TVOC is one of the three major types of indoor air quality pollution. TVOC is an organic substance with saturated vapor pressure over 133.32 Pa at room temperature. Its boiling point is between 50 and 250 degrees. It can be evaporated in the air at room temperature. Its toxicity, irritation, carcinogenicity, and special odor will affect the skin and mucosa and cause acute damage to the human body.
