Padrões físico-químicos
Os padrões físico-químicos são materiais de referência essenciais usados para garantir a precisão e a confiabilidade de várias medições analíticas na pesquisa científica e em aplicações industriais. Esta categoria inclui uma ampla gama de padrões, como padrões de condutividade, padrões de eletroquímica e padrões e reagentes ICP-OES/ICP-MS, que são críticos para análises elementares precisas e medições de condutividade. Soluções tampão de pH e reagentes de carbono orgânico/inorgânico total são vitais para manter os níveis de pH e medir o teor de carbono em amostras. Padrões da Farmacopeia Europeia (EP), Farmacopeia dos Estados Unidos (USP) e outras farmacopeias fornecem referências para o controle de qualidade farmacêutico. Outros padrões, como os de turbidez, densidade, refratometria e viscosidade, garantem medições precisas das propriedades físicas. Padrões especializados, como aqueles para as indústrias de vinho, laticínios e petroquímica, apoiam o controle de qualidade e a conformidade regulatória em setores específicos. Esses padrões físico-químicos desempenham um papel crucial na garantia da validade e reprodutibilidade dos resultados experimentais, apoiando uma ampla gama de aplicações, desde o monitoramento ambiental até testes farmacêuticos e ciência dos materiais.
