Scintillation is an analytical technique used to measure the ionizing radiation of an analyte. At the core of a scintillation counter is a sensor and detector, where the sensor is typically a scintillator crystal. Scintillation also includes liquid scintillation, radiometers and particle counters. Key features of scintillator counters include high resolution, automated multi-detection and high counting efficiency.
MicroScint™-20 cocktail was formulated to accept dilute aqueous samples at up to 20% loading (up to 25 µL in 100µL MicroScint™-20). With these sample types MicroScint™-20 cocktail mixes easily and completely upon agitation with an orbital shaker. It is the cocktail of choice for counting filters that have not been completely dried. MicroScint™-20 cocktail has an absolute, unquenched Tritium efficiency of approximately 52% when…
MicroScint™-E cocktail was developed for assays that require in-situ partitioning of the radionuclide-containing lipid phase from the aqueous phase in microplates. In this respect MicroScint™-E cocktail is suitable for extracting lipids or other non-polar compounds from the aqueous phase in such extraction assays. It enables direct counting of the samples after addition of the cocktail, because the label is preferentially take…
MicroScint™-O cocktail is suitable for counting non-polar organic samples such as hexane, heptane, ethyl acetate etc., and for dried filters. Since MicroScint™-O cocktail does not contain surfactants it is not miscible with water and is therefore unsuitable for aqueous samples. It is particularly useful for organic samples produced from enzyme inhibition assays. MicroScint™-O cocktail has an absolute, unquenched Tritium effici…
MicroScint™-PS cocktail was specifically formulated for polystyrene compatibility. It is suitable for use with virtually any type of microplate and provides long term counting stability. MicroScint™-PS has almost identical sample handling capabilities to MicroScint™-20 cocktail with respect to sample concentration and loading. MicroScint™-PS cocktail provides high counting stability with minimal change in count rate within 24…
Specifically formulated to accept up to 2.0 M ammonium formate at a 1:1 ratio with fast and easy mixing. Ultima-Flo AF will appeal particularly to those researchers using ammonium formate buffers to elute radiolabeled inositol phosphates from HPLC columns. Other samples such as 0.1 M imidazole, pH 7.5, are also easily accepted.
