Beschreibung

General description

We are committed to bringing you Greener Alternative Products, which belong to one of the four categories of greener alternatives. Phosphoric acid-doped polybenzimidazole (PBI) membranes offer a cleaner path to energy by enabling high-temperature fuel cells that efficiently convert hydrogen into electricity with low emissions. Their durability and proton conductivity make them ideal for sustainable power systems. Click here for more information.

Application

Phosphorsäure wird für die Herstellung von Anolyten verwendet, die in Lösungen für die kapilläre isoelektrische Fokussierung (CIEF) enthalten sind. Außerdem wird sie in FIA-CO-IRMS (flow injection analysis-chemical oxidation-isotope ratio mass spectrometry, „Durchflussanalyse-Chemische Oxidation-Isotopenratio-Massenspektrometrie“) als chemisches Oxidationsreagenz genutzt.

Other Notes

Konzentrierte Phosphorsäure, ca. 85 % H₃PO₄ (wässrig).

Disclaimer

Das Produkt kann erstarren, wird durch Erhitzen auf 50 °C verflüssigt.
