LABS2615

Lab Alpha-Beta Spectrometer
Phoswich Detectors can measure more than one type of radiation in the same detector – and distinguish between them. This not only enhances the accuracy of the measurement, it also drastically cuts instrumentation and operating cost.

Description:

Phoswich Detectors can measure more than one type of radiation in the same detector –
and distinguish between them. This not only enhances the accuracy of the measurement, it also drastically cuts instrumentation and operating cost.
The LABS 2615 is a modern Alpha & Beta spectroscopy system for activity measurements in laboratories. It is easy to operate and provides quick and reliable measurement results which are presented clearly arranged on a large graphical display with touch panel.
Using modern digital signal processing the system can accurately distinguish between Alpha & Beta-rays detected in the mixed Alpha and beta particles detected in the PVT.
The instrument is ideally suited for nuclide-specific activity measurements in the radionuclide laboratory.
The measurement electronics LABS 2615 is a modular designed 1/2 19" system accommodated in a desktop housing comprising computer unit, graphical display with touch panel and power supply unit. For data acquisition the measurement electronics includes two additional plug-in cards, a high voltage unit with preamplifier and an ADC for the acquisition of spectra. The Alpha & Beta spectrometer LABS 2615 has been designed for use in nuclear medicine, e.g. for in-vitro tests, radio- immunoassays or for the analysis of environ- mental samples, e.g. waste water, or for the detection of extremely low activities in food samples.
Various scintillation probes are available.
The measurement electronics LABS 2615 is operated via soft keys (graphical buttons on the display) which are queried via a pressure-sensitive foil (touch panel). This allows very intuitive user guidance. Pulse height spectra can be depicted graphically and evaluated, for example, via (ROI’s). Several service functions are available: background measurement, energy calibration and spectrum recording.
For single sample measurements there is an interactive start and stop mode with corresponding protocol printouts. To facilitate measurement operation, a comprehensive nuclide library with one parameter set for each nuclide is available to the user. The LABS 2615 supports communication with an external PC via RS232 interface Thus, it is possible to query and set parameters on the PC. Also, stored measurement data can be queried from the PC and processed on the PC. New program versions can easily be downloaded from PC to the flash E2prom using a terminal program. Parameters and service functions are contained in a hierarchically structured, very clearly arranged and user-friendly menu.
