Padrões catiónicos

A Avantor oferece uma ampla gama de padrões catiônicos certificados, projetados para calibração de instrumentos em aplicações de cromatografia de troca iônica (IC), que podem ser aplicados em análises ambientais ou de alimentos e no controlo de qualidade. A IC é uma técnica analítica usada para separação e quantificação de ânions e cátions em amostras aquosas. A Avantor oferece materiais de referência de alta pureza e bem definidos, ideais para quantificação em baixo nível de ppm ou análise de vestígios. Frascos de padrões catiônicos estão disponíveis para uma variedade de elementos.
