Amasampula emvelo evolumu ethile noma isikhathi aqoqwa ngokuya ngezidingo zesampula ze-TSP, PM10, uthuli lwemvelo neziphepho zothuli emkhathini.Ingxenye yesine yamasampula e-membrane yesihlungi eqoqwe aqoqwe ngokunembile emabhodleleni epulasitiki, enezela amanzi angama-20mL akhishwe nge-deionized, abese efakwa ku-50mL ngemuva kokukhishwa kumshini wokuhlanza we-ultrasonic futhi ahlungwe nge-membrane yesihlungi se-microporous engu-0.45μm.Ngemuva kwakho konke lokhu, isampula ingajovwa ukuze ihlaziywe.Kusetshenziswa i-CIC-D120 ion chromatograph, ikholomu ye-anion ye-SH-AC-3, 3.6 mM Na2CO3+4.5 mM NaHCO3 eluent kanye nendlela ye-bipolar pulse conductance, ngaphansi kwezimo ezinconyiwe zechromatographic, i-chromatogram imi kanje.
Kusetshenziswa i-CIC-D120 ion chromatograph, SH-CC-3 ikholomu yendawo, 5.5 mM MSA eluent kanye nendlela ye-bipolar pulse conductance, ngaphansi kwezimo zechromatographic ezinconyiwe, i-chromatogram imi kanje.
