Application

Ultima Gold XR LSC Cocktail is widely used to measure low-energy radionuclides. Metrology laboratories also use it for the standardization of radioactive solutions.

Features and Benefits

Ultima Gold XR LSC Cocktail has the following benefits:

  • A high flash point (150 °C) offers greater safety.
  • High sample load capacity and high counting efficiency − up to 50% for 3H. 
  • Compatible with alkaline samples.
  • It will not diffuse through polyethylene vials. 
  • Biodegradable. 
  • Compatible with polar organic solvents.

General description

Ultima Gold XR LSC Cocktail is a safer line of liquid scintillation cocktails (LSC) designed for a wide range of aqueous solutions. Liquid scintillation counting in radionuclide metrology involves preparing samples which are emulsions of aqueous radioactive solutions in liquid scintillation cocktails. Ultima Gold  XR LSC Cocktail technology is an alternative screening tool to alpha spectrometry and gas flow proportional counting.
