Ultima Gold MV is specifically formulated for the rapid uptake of aqueous and non-aqueous samples. It is recommended for counting wet or damp glass fiber filters from cell harvesters. It is also ideal for counting small volume samples in miniature vials and microtubes because of its reduced viscosity compared to other high flash point cocktails.

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.
Filter counting, or solid support counting as it is sometimes known, is probably best described as heterogeneous counting. The main difference between heterogeneous counting and homogeneous countingis that heterogeneous counting relies on 2 p geometry while 4 p geometry applies to homogeneous counting. An explanation of the terms 2 p and 4 p geometry is needed to appreciate the differences between the two counting techniques. I
A researcher was preparing samples and performing standard LSA counting using plastic vials and PerkinElmer’s ULTIMA™ Gold MV, a member of the ULTIMA Gold family of modern, safer cocktails. Unfortunately, the researcher was observing lower than expected 3H count rates and suspected that he may have exceeded the practical sample loading for this cocktail.
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.
One of PerkinElmer’s field representatives requested help for a researcher currently using PerkinElmer cocktails that contained toluene and xylene. The researcher hoped to “skip” two generations of cocktails and move up to PerkinElmer’s newest, ULTIMA Gold™, line of cocktail. The researcher’s primary concern was compatibility of the cocktail and sample.
