F-, Cl-, NO2-, SO42-, Na+, K+, NH4+, Mg2+, Ca2+, nezvimwewo zvinhu zvinodiwa kuti zvionekwe mukudzidza kwehutano hwemhepo uye kunaya kwemvura.Ion chromatography (IC) ndiyo yakanyatsokodzera nzira yekuongororwa kwezvinhu izvi ionic.
Atmospheric gas sample: Kazhinji shandisa solid absorption chubhu kana absorption fluid kuita sample.Kuti uongorore sulfur dioxide uye nitrogen oxides, zvinowanzodiwa kuwedzera huwandu hwakakodzera hweH2O2 mukusveta kana kubvisa mhinduro, oxidize SO2 kune SO42 -, uyezve. sarudza iyo neIC nzira.
Sample yekunaya kwemvura: Mushure mekuita sampling, inofanirwa kusefa nekukasika uye kuchengetwa mufiriji pa4 ℃, uye kuongororwa nekukurumidza sezvinobvira.Pakuongororwa kwemacations, asidhi yakakodzera inofanira kuwedzerwa mushure mesampling.
Particles sample:Environmental samples yerimwe vhoriyamu kana nguva yakaunganidzwa, uye 1/4 yesampuli yakaunganidzwa yakachekwa nemazvo.Mamembrane akacheneswa akachekwa nechigero chakachena uye akaiswa mubhodhoro repurasitiki (polyester PET), mvura yakasvibiswa inowedzerwa, inotorwa ne ultrasonic wave, ipapo mavhoriyamu akagadziriswa nebhodhoro revhoriyamu.Mushure mekunge iyo yakabviswa yapepetwa kuburikidza ne 0.45µm microporous filter membrane, iyo inogona kuongororwa; Zvisikwa zveguruva samples zvakadirwa mumabheki ane huwandu hwemvura yakashongedzwa uye ndokuburitswa ne ultrasonic wave, yakasefa uye yakatemwa nepamusoro nzira imwecheteyo.
