Detail Information

Ultima Gold™ AB is the world's first liquid scintillation cocktail specifically designed for alpha/beta discrimination in LSC. Ultima Gold™ AB is based on a unique, high flash-point solvent formulation that provides the slow pulse decay characteristics necessary for effective alpha/beta discrimination. The excellent sample holding capacity of Ultima Gold™ AB for a variety of both aqueous and acidic sample types makes it the cocktail of choice for most alpha/beta LSC applications.

Features:

  • Excellent alpha/beta discrimination
  • Excellent for strong mineral acids
  • High quench resistance
  • High sample capacity
  • Biodegradable
  • Very high flash-point of approximately 140°C

Application Note

Cocktail Selection for Tetrabutylammonium Hydrogen Sulfate and Acetonitrile Gradients

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.

LSC in Practice - Counting Aqueous Samples by LSC

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.

LSC in Practice - Measurement of 3H in Dilute Sulfuric Acid

One of PerkinElmer’s field sales engineers forwarded a request for assistance regarding the selection of the optimal cocktail for use with a sample containing 4.5 mL deionized water and 0.036 N sulfuric acid. The nuclide of interest was 3H, and polyethylene vials were used extensively in the laboratory.

LSC in Practice: LSC Technical Tips from PerkinElmer

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

Yellowing of Cocktail Mixture Containing Soil Extract

A researcher reported that his sample/cocktail mixture had turned yellow. After digesting soil samples, 4 mL1 M nitric acid were added to the digest. This sample was added to 16 mL ULTIMA Gold™ AB for counting. Over a period of 3 to 4 days, yellowing would occur accompanied by a drop in the tSIE value. The researcher wanted toknow what was causing the yellowing.
