Phapang Pakeng tsa Maemo a Bopaki ba Ho phatloha IIB le IIC

Lisebelisoa tse thibelang ho phatloha ka har'a Sehlopha sa II li arotsoe ka: Sehlopha sa IIA, Sehlopha sa IIB, le Sehlopha sa IIC. Lintlha li latela sehlopha sa maemo: IIC > IIB > IIA.

Boemo ba Sehlopha	Karolelano ea Khase	Likhase tse emetseng	Minimum Ignition Spark Energy
Tlas'a Morafo	I	Methane	0.280mJ
Lifeme Kantle ho Morafo	IIA	Propane	0.180mJ
	IIB	Ethylene	0.060mJ
	IIC	Haedrojene	0.019mJ

Lisebelisoa tsa khase tse fuoeng boemo ba ho thibela ho phatloha ha IIC li loketse likhase tsohle tse tukang; leha ho le joalo, Li-detectors tsa IIB li hlōleha ho lemoha H2 (haedrojene), C2H2 (acetylene), le CS2 (carbon disulfide), e leng litšobotsi tsa sehlopha sa IIC.
