Ultima Gold™ XR is a safer liquid scintillation cocktail with a very high sample load capacity. Ultima Gold XR is the right choice when large sample volumes need to be counted or when miniature vials are required for higher throughput. This results in a reduced cost per sample and helps keep radioactive waste to a minimum. Ultima Gold XR is compatible with alkaline samples.

A researcher was counting 1 mL fractions and wished, to add a maximum of 2 mL of a “safer” cocktail to, help comply with local regulations. The sample is a gradient run from 100% to 45% of solution A, the remainder is solution B.
A researcher wanted to know the percentages of the elements present in various commonly used cocktails to satisfy regulations concerning the disposal of cocktail waste by incineration.
The primary objective of all sample preparation procedures for liquid scintillation counting (LSC) is to obtain a homogeneous solution for efficient energy transfer from the sample to the LS cocktail. Aqueous solutions are some of the simplest and most commonly found in liquid scintillation analysis. In general, they provide the environment necessary for many assays and separations, and include the most encountered solvent media for the numerous radioisotopes usedin LSC.
A researcher observed a count rate that was lower than expected with a tSIE of 300-400. The sample was bile acid that had been recovered from mouse feces. Water was used to rehydrate the feces.
A researcher contacted us to learn how to “bind” a100 µL NaH14CO3 (sodium bicarbonate) and sea water sample to prevent loss of activity due to gaseous release during sample preparation.
A researcher was performing ligand binding experiments, and asked for assistance to select a new, safer, cocktail for processing his 30,000 samples per year., The researcher wished to avoid the time-consuming task of testing a wide variety of cocktails and turned to PerkinElmer for a solution.
