Abstract: A digitally temperature compensated oscillator (TCO) system is provided which is capable of ascertaining and memorizing in an EEPROM-based look-up table, appropriate digital values of a temperature-compensating tuning voltage to the TCO during calibration. An on-board temperature sensing mechanism tracks variations in temperature in the TCO and produces an analog voltage value corresponding to the instantaneous temperature. The voltage value of the sensor output is digitized and designated to constitute an address into the EEPROM based look-up table. As the temperature changes, the digitized output of the temperature sensor and hence the address to the EEPROM changes accordingly.

Abstract: Apparatus and a method useful for identifying and verifying which radionuclide is present in a test sample for use in a liquid scintillation counter is disclosed. The invention is directed to measuring a quench-indicating parameter of the sample and an external source quench-indicating parameter. The measured values are compared to known radionuclide equations to determine if an identifying fit exists. If the measured values are determined to satisfy, one of the known radionuclide equations, then the identity of a radionuclide is established. In a multilabel sample the measured values may be used to identify the radionuclide having the highest end point maximum energy.
