ʻO nā laʻana kaiapuni o kahi leo a i ʻole manawa e hōʻiliʻili ʻia e like me nā koi sampling o TSP, PM10, lepo kūlohelohe a me nā ʻino lepo i ka lewa.ʻO ka hapaha o nā ʻāpana membrane kānana i hōʻiliʻili ʻia e ʻoki pono ʻia i loko o nā hue plastik, e hoʻohui i ka wai deionized 20mL, a laila hoʻonui ʻia i 50mL ma hope o ka unuhi ʻia ʻana i loko o ka mea hoʻomaʻemaʻe ultrasonic a kānana ʻia e kahi membrane kānana microporous 0.45μm.Ma hope o kēia mau mea, hiki ke hoʻokomo ʻia ka hāpana no ka nānā ʻana.Ke hoʻohana nei i ka CIC-D120 ion chromatograph, SH-AC-3 anion column, 3.6 mM Na2CO3+4.5 mM NaHCO3 eluent a me ka bipolar pulse conductance method, ma lalo o nā kūlana chromatographic i ʻōlelo ʻia, penei ka chromatogram.
Ke hoʻohana nei i ka CIC-D120 ion chromatograph, SH-CC-3 cation column, 5.5 mM MSA eluent a me ka bipolar pulse conductance method, ma lalo o nā kūlana chromatographic i ʻōlelo ʻia, penei ka chromatogram.
