Unpressurized Gas Standards

Analytics supplies unpressurized transferable gas standards allowing customers to perform calibrations on virtually any counting container using an actual gas. These standards are supplied in a 33-mL glass sphere with two stopcocks and a septum port for transfer. A transfer kit, including a calibrated gas syringe and instructions, can be purchased to perform multiple accurate transfers and calibrations from the standard.

Radionuclides available as unpressurized gas standards are ¹³³Xe, ¹²⁷Xe, ⁸⁵Kr, and a mixed standard including all three radionuclides. The mixed standard provides the widest energy range calibration practical with real radioactive gasses. The mixed gas standard has gamma-ray emissions at 81, 145, 172, 202, 375, and 514 keV.
