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
