General Description
The Portable Liquid Scintillation Counting System accurately quantitatively measures Carbon-14, Tritium and most other radioactive materials. Gamma ray counting is optional. PC interface and hard copy printer are optional. The Portable Liquid Scintillation Counter has a 3 Vial capacity for faster thru-put and easy comparison sample to calibration standard or to background. This is an all-in-one unit thus enhancing portability. End Users: state and federal health agencies, nuclear power plants, small labs, us military drinking water quality units, citizen groups, municipal utilities.
Technical Description
Using the most sensitive method of detecting and quantitating beta emitting isotopes mixing the sample with liquid scintillation fluor and counting each individual scintillation event with a photomultplier counter. An energy analyzer further selects the pulses and delivers the true signal. Optionally, gamma ray counting is achieved by inserting and optically coupling an Nal(Tl) scintillation well crystal on the PM tube. Scintillation counts which are detected by PM tubes are processed by a fully adjustable single channel analyzer which is centered on the energy peak of the isotope being measured.
