Natriumstandarder

Avantor tilbyder en bred vifte af certificerede kationiske standarder designet til instrumentkalibrering i ionbytningskromatografi (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 referencematerialer med høj renhed, der er veldefinerede, og som er ideelle til kvantificering med lavt ppm-niveau eller sporanalyse. Flasker med kationiske standarder er tilgængelige for en række grundstoffer.
