1. I-VOC
Izinto ze-VOC zibhekisela ezintweni eziphilayo eziguquguqukayo. I-VOC imele izinto eziphilayo eziguquguqukayo. I-VOC ngomqondo ojwayelekile iwumyalo wezinto eziphilayo ezikhiqizayo; Kodwa incazelo yokuvikelwa kwemvelo ibhekisela ohlotsheni lwezinto eziphilayo eziguquguqukayo ezisebenzayo, ezingadala umonakalo.
Eqinisweni, ama-VOC angahlukaniswa ngezigaba ezimbili:
Enye incazelo ejwayelekile ye-VOC, kuphela ukuthi yini ama-organic compounds aguquguqukayo noma ngaphansi kwaziphi izimo ama-organic compounds aguquguqukayo;
Okunye incazelo yezemvelo, okungukuthi, lezo ezisebenzayo, lezo ezibangela umonakalo. Kusobala ukuthi ukuguquguquka kwesimo sezulu kanye nokubamba iqhaza ekusabeleni kwe-photochemical emoyeni kubaluleke kakhulu ngokombono wezemvelo. Ukungaguquguquki noma ungazibandakanyi ekusabeleni kwe-photochemical emoyeni akusho ingozi.
2. AMA-VOCS
EShayina, ama-VOC (ama-volatile organic compounds) abhekisela kuma-organic compounds anomfutho womusi ogcwele ongaphezu kwama-70 Pa ekushiseni okujwayelekile kanye nephuzu lokubila elingaphansi kwama-260℃ ngaphansi kwengcindezi evamile, noma wonke ama-organic compounds anomfutho womusi ohambisanayo ongaphezu kwama-10 Pa kuma-20℃.
Ngokombono wokuqapha kwemvelo, libhekisela kuma-hydrocarbon angewona i-methane aphelele atholwe yi-hydrogen flame ion detector, ikakhulukazi afaka phakathi ama-alkanes, ama-aromatics, ama-alkenes, ama-halohydrocarbons, ama-esters, ama-aldehydes, ama-ketones kanye nezinye izinto eziphilayo. Nasi isihluthulelo sokuchaza: Ama-VOC nama-VOCS empeleni ayisigaba esifanayo sezinto, okungukuthi, isifinyezo sama-Volatile Organic Compounds, ngoba ama-Volatile Organic Compounds ngokuvamile anezingxenye ezingaphezu kwesisodwa, ngakho-ke ama-VOCS anembe kakhudlwana.
3. I-TVOC
Abacwaningi bekhwalithi yomoya wangaphakathi bavame ukubiza zonke izinto ezisebenzisa igesi ze-Organic zangaphakathi abazithatha futhi bazihlaziye njenge-TVOC, okumelela uhlamvu lokuqala lwamagama amathathu athi Volatile Organic Compound, lawo mazwi alinganiswayo aziwa ngokuthi yi-Total Volatile Organic CompoundS (TVOC). I-TVOC ingenye yezinhlobo ezintathu zokungcola ezithinta ikhwalithi yomoya wangaphakathi.
I-World Health Organization (WHO, 1989) ichaze ama-total volatile organic compounds (TVOC) njengama-volatile organic compounds ane-melting point engaphansi kwe-hot temperature yegumbi kanye ne-boliting point ephakathi kuka-50 no-260℃. Ingahwamuka emoyeni lapho i-room temperature ishisa. Ine-toxic, iyacasula, ibangela umdlavuza futhi inephunga elikhethekile, elingathinta isikhumba kanye ne-mucous membrane futhi libangele umonakalo omkhulu emzimbeni womuntu.
Ngamafuphi, empeleni, ubudlelwano phakathi kwalaba abathathu bungachazwa njengobudlelwano bokufakwa:
