Liquid Scintillation Counting Standards

Quenched

Custom quench standard sets (typically 5-10 vials) for liquid scintillation counting can be prepared using the customer's LS counting fluid (cocktail). Standards are prepared gravimetrically and flame sealed in glass LS vials. Radionuclides available include, but are not limited to the following:

³H
¹⁴C
³⁶Cl
⁵⁵Fe
⁶³Ni
⁹⁹Tc
⁸⁹Sr
⁹⁰Sr

After preparation, the quenched sets are counted on one of Analytics' calibrated liquid scintillation counting systems. Contact us with your specific requirements. Customers can supply their specific type of liquid scintillation vials.

Unquenched

A set contains ³H, ¹⁴C, and a background sample. Activities are 5 kBq (300,000 dpm) for ³H and 2.16 kBq (130,000 dpm) for ¹⁴C.

Alpha/Beta

A set contains ²⁴¹Am, ³⁶Cl and a background sample. Typical activities are 1.6 kBq (100,000 dpm) for each isotope. Other radionuclides and activities are available upon request.
