When the sample is purely organic, it can be mixed with a lipophilic cocktail.Liquid scintillation cocktails, solid scintillant alternative (MeltiLex top.PerkinElmer Technical Support offers you the expertise you need to confirm your choice or can recommend the best cocktail for a particular application.As the majority of beckman samples applied in LSC are aqueous-based, most of the LSC cocktails consist of: The aromatic, organic solvent, scintillation the scintillator(s) or fluors, the surfactants.Top, liquid scintillation cocktails, a variety of scintillation cocktails is available to optimize the counting of almost any specific sample.p p Liquid Scintillation Counter Overview /p p Step by beckman Step Procedures for LSC /p p Things to Consider /p p 3What is a Scintillation Counter - LSC?p p LSC Printout /p p A counter Positive Control is a standard made up by the LSC manufacturer or in your labwith a known DPM/CPM value.Caps 6000167, pico Glass Vial.0 mL, foil-lined urea screw caps 6000096 Econo Glass Vial.0 mL Foil-lined urea screw caps 6000097 Econo Glass Vial.0 mL Poly screw caps 6000128/6000129/6000349 High Performance Glass Vial.0 mL Foil-lined urea screw caps 6000134 High Performance Glass.p p How scintillation to perform counting using LSC /p p Add Scintillation CocktailNote: Chemical splash goggles, gloves and lab coat are required when dispensing common brands of scintillation cocktail.No liquid scintillation cocktail is required, as scintillant is already embedded in the walls of the microplate. Almost all cocktails will give counting results with any application, but the game quality and reproducibility of the data will depend on the choice of the cocktail as portable well as on the sample composition, volume, temperature, and counting device.
The LSC value must be within 5 of the standard value.
