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.
In Liquid Scintillation Counting (LSC), preparationof biological samples has always been treated as aspecial case because of the difficulties associated with their preparation for counting. In general, all biological samples contain components not generallyfound in any other sample types, therefore it is of benefit to understand the composition of these samples to fully understand the need for the slightly unusual sample preparation methods.
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.
A researcher had been using PerkinElmer’s Biological Sample Preparation Guide in an attempt to process sheep plasma samples. The samples were labeled with 3H and 14C. The current procedure called for 0.1 mL or 0.2 mL of plasma with 0.5 mL of deionised (DI) water in 15 mL of ULTIMAGold™. After several hours, the samples would turn cloudy and separate. The researcher requested our help to refine her sample preparation technique or recommend conversion to an alternate cocktail.
The manager of one of PerkinElmer’s application support departments requested assistance for a researcher who was performing catecholamineassays. After sample preparation with ULTIMAGold™, the researcher had been experiencing high backgrounds.
