Description

General description

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.

Application

Suitable as standard for electrospray ionisation MS (ESI)

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.

Features and Benefits

Frequently used in devices such as phosphor screens for medical imaging, scintillators, calorimeters and a variety of particle detectors.
