Ukunemba kwemiphumela yokuhlolwa kanye nokunemba kweziphetho zesahlulelo kuncike ekumeleleni kwamasampula athathiwe.Isampula elingameleli aligcini nje ngokudala ukumoshwa kwabasebenzi, izinsiza ezibonakalayo nesikhathi, kodwa futhi kuholela eziphethweni ezingalungile kanye nokulahlekelwa okukhulu.Kumasampuli kawoyela anezidingo ezikhethekile zokusampula, njengokuhlaziywa kwe-spectrometry yegesi emafutheni, amanzi amancane kuwoyela, i-furfural kawoyela, ukuhlaziywa kwensimbi kuwoyela nokungcoliswa kwezinhlayiyana (noma ukuhlanzeka) kawoyela, njll. Kunezidingo ezihlukene kusukela endleleni ukuya isitsha samasampula kanye nendlela nesikhathi sokugcina.
Manje izinyathelo zokuphepha zesampula zokuhlaziya i-chromatographic zibaliwe:
I-HV Hipot GDC-9560B Power System Amafutha I-Chromatography Analyzer
(1) Ukuthatha amasampula kawoyela ukuze kuhlaziywe igesi esemafutheni ngechromatographic, isirinji yezokwelapha ehlanzekile neyomile engu-100mL ekwazi ukungena komoya kahle kufanele isetshenziselwe ukuthatha amasampula ngendlela evalekile.Akumele kube namabhamuza omoya emafutheni ngemva kokuthatha isampula.
(2) Amafutha aqoqwe ekhoneni elifile lomzila kufanele akhishwe ngaphambi kokuba kuthathwe amasampula, ngokuvamile u-2~3L kufanele akhishwe ngaphambi kokuthatha amasampula.Uma ipayipi likhulu futhi lide, kufanele likhishwe okungenani kabili umthamo walo.
(3) Ipayipi elixhuma amasampula kufanele linikezelwe, futhi ipayipi lerabha elishiselwe nge-acetylene alivunyelwe ukusetshenziswa njengepayipi elixhumayo lokwenza amasampula.
(4) Ngemva kokuthatha isampula, umnyombo wesirinji kufanele ugcinwe uhlanzekile ukuze kuvinjwe ukuminyana.
(5) Kusukela ekuthathweni kuya ekuhlaziyweni, amasampula kufanele avikelwe ekukhanyeni futhi kufanele athunyelwe ngesikhathi ukuze kuqinisekiswe ukuthi angaqedwa phakathi kwezinsuku ezi-4.
