The
63
Ni isotope
The radioactive isotope used in the cell is
63
Ni. It is plated onto the inner
surface of the cell body and is solid at temperatures used in chromatography.
Some other properties are listed in Table 1.

µECD licenses
Customers in the United States can purchase a µECD under either a General
License or a Specific License. Customers outside the United States should
contact their local Agilent sales office for information.
The license details below reflect U.S. regulations.
Specific license
Specific license µECDs require you to obtain a Materials License from the
Nuclear Regulatory Commission (NRC) or local state agency, permitting you to
possess the amount and kind of radioisotope used in the detector. You can
typically ship, sell, or transfer the µECD to other Specific Licensees. If the
license permits, you may also open the µECD for cleaning.
General license
General license µECDs do not require a Materials License. You become a
General Licensee automatically when you purchase a µECD directly from Agi-
lent Technologies. Some states may require that you register the µECD with a
state agency.
Certain restrictions apply to General Licenses:
• Owners may not open the µECD cell.
• Owners shall not modify the cell in any manner.
• Owners shall not use any solvent, including water, to internally clean the
cell.
Half-life: 101.1 years
Emission: 65.87 keV max., beta radiation
Melting point: 1453 °C
Dimensions of the active part
of the µECD:
Inside diameter: 6 mm
Height: 4.2 mm
Total activity (µECD cell): 555 MBq (15 millicuries) maximum
