Typical (recommended) application of the method

Talajvízből, ivóvízből, szennyvízből a kis koncentrációban előforduló anionok meghatározása.

Detailed Protocol

Kromatográfiás mérés, ivóvizek, talajvizek esetében mintaelőkészítést nem igényel, csak szűrést (0,45 mikrométer pórusátmérőjű szűrőn át), szennyezettebb minták esetében a mintát tisztítani kell az analitikai oszlop védelmében.

Strengths

Nagyon pontos ionkoncentráció meghatározására képes módszer.
A berendezés működése közben nem igényel állandó emnberi felügyeletet.

Weaknesses

Az analitikai oszlopot, eluens generátort, szupresszort viszonylag gyakran kell cserélni, beszerzésük nehézkes, szervízhálózat fejletlen.
Csak tiszta, kis vezetőképességű vizeknél alkalmazható, vagy hígítani kell a mintát: ennek oka, hogy a detektor felső mérési határa 2800 mikroSiemens, e fölött hígítani kell, mellyel az alsó méréshatár romlik, a nem mérendő anionok tisztító oszlopokkal eltávolíthatók.

Possibilities

Származékképzéssel (anionképzéssel) például ózon koncentráció meghatározására.
kapcsolt technikák: IC-MS-el vagy HPLC-vel össze lehet kapcsolni (arzén 3+ és 5+ szétválasztása)
Alkalmazható talaj oldható anionkoncentrációjának meghatározására talajkivonatból.

Lessons learned

Nagyon pontos eredményt ad, a talajvíz lebegőanyaga eltömítheti az oszlopot, ezért a mintákat minden esetben szűrni kell 0,45 mikrom pórusátmérőjű szűrőn.
