Brief concise description explaining the innovation

A hordozható XRF készülék jól használható talajok fémtartalmának meghatározásra, alkalmazása időt és költséget takarít meg a hagyományos analitikai vizsgálatokkal szemben.

Typical (recommended) application of the method

talajminták fémtartalmának meghatározására, de alkalmazzák ötvözetek, műanyagok, egyéb szilárd fázisú minták fémtartalmának meghatározására

Detailed Protocol

A talajmintákat a laboratóriumban homogenizáljuk, szárítjuk, porítjuk, majd zárható műanyag zacskóban vagy mintatartóba helyezve mérjük. A műszert bekapcsolás után, minden esetben kalibráljuk. A mintákat azonos ideig mérjük, ezzel kiküszöbölve a különböző időtartamú mérések által okozott hibát. A mérések optimális hossza 60-120 másodperc.

Strengths

gyors, olcsó mérés, megfelelő pontosság, egyszeri beruházás után viszonylag alacsony egy mérésére jutó költség,

Weaknesses

a műszeres analitikai méréshez képest, nagyobb szórás, kisebb pontosság

Possibilities

ötvözetek, műanyagok fémtartalmának mérése
