Ukuze uphucule iindleko zenkqubo yokuvelisa iikhemikhali kwaye ugcine imveliso esemgangathweni ophezulu, kufuneka ubambe ulwelo lwenkqubo olumeleyo ukuze luhlalutywe elebhu rhoqo. Ukuthatha iisampulu (ekwaziwa ngokuba yi-spot sampling, i-field sampling, okanye i-rational sampling) kunceda ukuqinisekisa iimeko zenkqubo kunye nokuqinisekisa ukuba imveliso evelisiweyo iyahlangabezana neemfuno zangaphakathi okanye ezisekelwe kubathengi.
Imithetho esisiseko yokuvavanya iisampulu
1: Isampulu kufuneka imele imeko yenkqubo, kwaye iprobe mayisetyenziswe ukukhupha isampulu embindini wepayipi yenkqubo ukuze kuthintelwe utshintsho lwesigaba ngexesha lokuthuthwa kwesampulu.
2: Isampulu kufuneka ibe sexesheni. Ukufinyeza ixesha lokuthuthwa ukusuka kwindawo yokukhupha ukuya kwilebhu kuyanceda ukuqinisekisa ukuba iimeko zenkqubo zibonakaliswa ngokuchanekileyo.
3: Isampulu mayibe msulwa. Kuphephe ukuba ityhubhu ifile kwindawo engasekhoyo kumjelo wesikhongozeli sesampulu kwaye uvumele ukucocwa nokuhlanjwa ngokwaneleyo kwenkqubo yokuvavanya ukuze kuncitshiswe amathuba okungcola.
Cinga ngolwelo lwenkqubo apho igesi inyibilikiswa khona. Ukuba ubushushu buyanda kwaye uxinzelelo luyancipha, igesi enyibilikisiweyo inokubila iphume kwisampuli. Okanye cinga ngesampuli yegesi enobushushu obuphantsi kunye noxinzelelo oluphezulu, olunokubangela ukuba ulwelo luqine kwaye lwahlukane nesampuli. Kwimeko nganye, ukwakheka kwesampuli kutshintsha ngokusisiseko, ngoko ke akusakwazi ukumela iimeko zenkqubo.
Ngenxa yezizathu ezingentla, kuyimfuneko ukusebenzisaiibhotile zesampuluukuqokelela igesi okanye igesi enyibilikisiweyo ukuze kugcinwe isigaba esichanekileyo kwaye kugcinwe ukumelwa kwesampuli. Ukuba igesi inetyhefu, isilinda ikwasebenza kakuhle ekukhuseleni ingcali yesampuli kunye nokusingqongileyo kumsi okanye kwi-exhaust emissions.
