What isVOC, Maybe many people are unfamiliar with this name, sometimes we need to detect certain gases, maybe it belongsVOCof a kind,VOCThe full name is (Volatile organic compounds), in the ordinary sense ofVOCIt refers to volatile organic compounds; but the definition in the sense of environmental protection refers to a kind of active volatile organic compounds, that is, a kind of volatile organic compounds that will cause harm. When it comes to environmental protection, we have to mention the World Health Organization (WHO），WHOthinkThe melting point is lower than room temperature and the boiling point is50～260℃The general term for volatile organic compoundsIt isVOC. The most convenient and common way is to define which substances belong to the boiling point.VOCThe most general consensus is thatVOCRefers to those with boiling points equal to or lower250℃of chemical substances. So the boiling point is over250℃Those substances are not classified.VOCcategory, often referred to as plasticizersThis is what BASF thinks they are.VOC。

I understandVOCThe definition of thisVOCIt can't happen for no reason,VOCThe outdoor mainly comes from fuel combustion and transportation; the 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 the human body itself. In our daily lifeVOCEverywhere, whyVOCCan it be so permeated in our daily lives?VOCThe main components are: hydrocarbons, halogenated hydrocarbons, oxygen hydrocarbons and nitrogen hydrocarbons, which include:Benzene series, organic chlorides, freon series, organic ketones, amines, alcohols, ethers, esters, acids and petroleum hydrocarbon compoundsWait. Description of these ingredientsVOCMore may exist in chemical, petroleum and other industrial plants,VOCDoes this mean that our lives are at risk?

The answer is yes, whenVOCWhen a certain concentration is reached, it will causeHeadache, nausea, vomiting, fatigueand other symptoms, even when seriousConvulsions, coma, damage to the liver, kidneys, brain and nervous system, causing memory loss and other serious consequencesA little careless will be chronic poisoning, and finally threaten the safety of life and property.

So againstVOCsafety standards,China's "indoor decoration materials harmful substance content" provisions: wall paintVOCContent shall be≤200G/The environmental labeling certification standard also requires that the wall paint be removed from the water.VOCcontent to be≤80G/The standards in developed countries are more stringent, such as the European Union standard for wall paint.VOCContent shall be≤75G/l. DueVOCitself has a great harm, has been the social metaphor for human“Invisible Killer”. How to reduce and eliminate wood lacquerVOCIt has also become a new development goal for the coating industry.So how can we detectVOCThe content of, or know the environmentVOCWhat about the concentration?

shenzhen agent of the ukAlphasense PIDThe sensor can be solved perfectlyVOCThe detection problem,PIDPhotoionization detector is the use of organic gas under the excitation of ultraviolet light source will produce gas ionization, ionized "fragments”With positive and negative charges, so as to generate a current between the two poles, the detector amplifies the current, through the instrumentation equipment can and displayVOCsconcentration of gas. United KingdomAlphasenseofPIDThe sensor can detect a varietyVOCgas,High sensitivity, good linearity, high resolution. Among themPID-A1It is commonly used with indoor portable detectors, chemical plant environmental testing, etc., can be effective inVOCThe concentration has not yet threatened the safety of life and property. The personnel who have been notified to the scene in time are the top choice.
