Standard fisico-chimici
Gli standard fisicochimici sono materiali di riferimento essenziali utilizzati per garantire la precisione e l'affidabilità di varie misurazioni analitiche nella ricerca scientifica e nelle applicazioni industriali. Questa categoria include una vasta gamma di standard come gli standard di conducibilità, gli standard di elettrochimica e gli standard e reagenti ICP-OES/ICP-MS, che sono cruciali per analisi elementari precise e misurazioni della conducibilità. Le soluzioni tampone di pH e i reagenti per il carbonio organico/inorganico totale sono vitali per mantenere i livelli di pH e misurare il contenuto di carbonio nei campioni. Gli standard della Farmacopea Europea (EP), della Farmacopea degli Stati Uniti (USP) e di altre farmacopee forniscono punti di riferimento per il controllo di qualità farmaceutico. Altri standard come quelli di torbidità, densità, rifrattometria e viscosità assicurano misurazioni precise delle proprietà fisiche. Gli standard specializzati, come quelli per le industrie del vino, lattiero-casearia e petrolchimica, supportano il controllo di qualità e la conformità normativa in settori specifici. Questi standard fisicochimici giocano un ruolo cruciale nel garantire la validità e la riproducibilità dei risultati sperimentali, supportando un'ampia gamma di applicazioni, dalla monitoraggio ambientale ai test farmaceutici e alla scienza dei materiali.
