(e-China) HS-12A Isampula ye-Headspace–isebenza ngokuzenzakalelayo
Okomnotho Futhi Okuhlala Njalo: Izingxenye zensimbi zihlolwe isikhathi eside futhi zizinzile futhi zihlala isikhathi eside.
Ukusebenza okulula: ukuhlaziya isampula okuzenzakalelayo ngokugcwele.
I-adsorption eyinsalela ephansi: Lonke ipayipi lenziwe ngezinto ezingasebenzi, futhi lonke ipayipi liyashisisa futhi liyagqunywa.
