Ukwandisa izindleko zenqubo yokukhiqiza amakhemikhali nokugcina umkhiqizo wekhwalithi ephezulu, udinga ukuthwebula uketshezi lwenqubo olumele ukuze luhlaziywe elabhorethri njalo. Ukusampula (okubuye kwaziwe ngokuthi ukusampula kwendawo, ukusampula kwendawo, noma ukusampula okunengqondo) kusiza ukuqinisekisa izimo zenqubo kanye nokuqinisekisa ukuthi umkhiqizo okhiqizwayo uyahlangabezana nokucaciswa okususelwe kwangaphakathi noma kwekhasimende.
Imithetho eyisisekelo yamasampula
1: Isampula kumele imele isimo senqubo, futhi i-probe kufanele isetshenziselwe ukukhipha isampula phakathi kwepayipi lenqubo ukuze kugwenywe ukuguqulwa kwesigaba ngesikhathi sokuthutha isampula.
2: Isampula kufanele ibe ngesikhathi. Ukunciphisa isikhathi sokuthutha ukusuka endaweni yokukhipha kuya elabhorethri kuyasiza ukuqinisekisa ukuthi izimo zenqubo ziboniswa ngokunembile.
3: Isampula kufanele ihlanzeke. Gwema indawo efile ye-tube enhla nomfula wesiqukathi sesampula futhi uvumele ukuhlanzwa okwanele nokuguquguquka kwesistimu yamasampula ukuze unciphise amathuba okungcola.
Cabangela uketshezi lwenqubo lapho igesi incibilika khona. Uma izinga lokushisa likhuphuka futhi ingcindezi iyancipha, igesi encibilikile ingase iphume kusampula. Noma cabangela isampula yegesi enezinga lokushisa eliphansi kanye nokucindezela okuphezulu, okungase kubangele uketshezi ukuthi lujiye futhi luhlukane nesampula. Esimeni ngasinye, ukwakheka kwesampula kushintsha kakhulu, ngakho-ke ngeke isakwazi ukumela izimo zenqubo.
Ngenxa yezizathu ezingenhla, kuyadingeka ukusebenzisaisampula amabhodlelaukuqoqa igesi noma igesi eliwuketshezi ukuze kugcinwe isigaba esifanele futhi kugcinwe ukumelela kwesampula. Uma igesi inobuthi, isilinda siphinde sisebenze kahle ekuvikeleni uchwepheshe oyisampula nendawo ezungezile entuthuni noma ekukhishweni kwesisi.
