Kationstandarder

Avantor tilbyder et bredt udvalg af certificerede kationiske standarder designet til instrumentkalibrering i ionbytte-kromatografi (IC) applikationer, som kan anvendes til miljø- eller fødevareanalyse og kvalitetskontrol. IC er en analytisk teknik, der anvendes til separation og kvantificering af anioner og kationer i vandige prøver. Avantor tilbyder højrenhed, veldefinerede referencematerialer, ideelle til lav-ppm-niveau kvantificering eller sporanalyse. Flasker med kationiske standarder fås for en række elementer.
