Application

Ultima Gold™ 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™ 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™ 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™ LSC Cocktail technology is an alternative screening tool to alpha spectrometry and gas flow proportional counting.
