Hionic-Fluor is a cocktail tailored for samples of high ionic strength and solubilized samples in strong alkaline media. Hionic-Fluor is a pseudocumene-based LSC cocktail, formulated for counting concentrated salt or alkaline solutions, and is recommended for counting concentrated sucrose or cesium chloride gradients.

A researcher had been trying to use PerkinElmer’s Soluene®-350 to digest agarose gels.
A researcher called one of our offices to report a suspected contamination problem with one batch of PerkinElmer’s Hionic-Fluor™
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 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 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.
Difficulties performing the solubilization of hair prompted one researcher to contact our offices for assistance. This laboratory was using PerkinElmer’s Soluene®-350 to solubilize other materials and hoped that it could also be used for their new hair samples.
