Our high flash-point liquid scintillation cocktail allows you to determine low levels of ³H in a wide range of water samples without requiring distillation. Ultima Gold LLT accepts up to 54% tap water, river water, rain water and even sea water, with 3H counting efficiencies of approximately 30% and with very low background levels. When used with the Tri-Carb® time-resolved low-level liquid scintillation analyzers, backgrounds are reduced even further, resulting in minimum detectable activities of less than 1.1Bq/L-1 (500 minute count time).

Features:

• High water capacity - up to 54%
• High counting efficiency
• Very low background levels
• For bioassay of urine up to 40% capacity, allowing detection levels of less than 10Bq/L-1 (500 minute count time)
• Heavy metal radionuclide sample capacity, up to 18% of 2M HNO₃, 2M HCl and 2M H₃PO₄ for alpha, beta and alpha/beta counting
• No diffusion through polyethylene vials
• High flash-point of approximately 140°C
