Allgemeine Beschreibung

Cesium iodide is a simple ionic salt. It has the capacity to undergo second order transformation from cubic B2 structure to body-centered tetragonal structure at low pressures. It is mostly used as input screens of X-ray image intensifiers.

Anwendung

Suitable as standard for electrospray ionisation MS (ESI)[1][2]
Cesium iodide has been used as calibration standard during native electrospray ionization time-of-flight mass spectrometry (ESI-TOF MS) analysis for measuring protein samples, from protein aggregates.

Leistungsmerkmale und Vorteile

Häufig in Geräten wie Leuchtstoff-Bildschirmen für die medizinische Bildgebung, Szintillatoren, Kalorimetern und in einer Vielzahl von Teilchendetektoren verwendet.
