VOC is a volatile organic compound (volatile organic compounds) short. However, due to the wide variety of VOCs, it is impossible to include all volatile organic compounds in monitoring and supervision, so some indicators are used to characterize VOCs in China, such as VOCs, TVOC, non-methane total hydrocarbons and hydrocarbons. So what is the difference between TVOC, VOC, VOCs gas detectors ? The following is a brief introduction by yi yun Tian:

differences between TVOC, VOC and VOCs gas detectors:

1. conceptual differences:

TVOC: generally, all indoor organic gaseous substances sampled and analyzed are called TVOC, which is the abbreviation of the first letter of VolatileOrganicCompound 3 word. all kinds of measured VOCs are collectively called total volatile organic compounds TVOC(TotalVolatileOrganicCompounds)

VOC:VOC is the English abbreviation of volatile organic compounds (volatileorganiccompounds).VOC in the ordinary sense refers to volatile organic compounds; but the definition of environmental protection refers to a kind of active volatile organic compounds, that is, a kind of volatile organic compounds that will cause harm.

VOCs: in our country, VOCs(volatileorganiccompounds) volatile organic compounds refer to organic compounds with saturated vapor pressure greater than 133.32Pa at normal temperature and boiling point below 50~260 at normal pressure, or any organic solid or liquid that can volatilize at normal temperature and normal pressure.

2. contains material differences:

TVOC:TVOC refers to the sum of all measured VOCs, mainly from fuel combustion and transportation: while indoors, it mainly comes from combustion products such as coal and natural gas, smoke from smoking, heating and cooking, adhesives, coatings, paints, plates, wallpapers, etc. in construction and decoration materials, furniture, Household appliances, furniture, cleaning agents and emissions from the human body itself.

VOC:VOC mainly comes from fuel combustion and transportation outdoors; Indoor mainly comes from combustion products such as coal and natural gas, smoke from smoking, heating and cooking, and emissions from building and decoration materials, furniture, household appliances, cleaning agents and human body itself.

VOCs: VOC, like VOC, is a plural expression of volatile organic compounds (VOC).

to sum up, it is the difference between TVOC, VOC and VOCs gas detectors, hoping to be helpful to everyone.
