β- radioactivity HPLC flow detector
The most sensitive detection method for low energy β- nuclides

  • Perfect for GLP applications
  • Lowest background
  • High efficiency
  • Most sensitive
  • Liquid or solid scintillator
  • Optional dual BGO detectors for pet metabolite analysis

Liquid scintillation is the most sensitive detection method for low energy beta nuclides such as H-3. Alternative internal solid scintillators of suitable material and particle size are offering almost the same efficiency for C-14 as liquid scintillator admixtures. Environmental and cost considerations have promoted internal solid scintillators.


Thin layer radiochromatograph (TLC-Scanner)
The best choice for fast and reliable pet and spect radio purity determination

  • Collimators for different energy ranges
  • Extremely high counting rate
  • Manual or automatic peak integration and TLC evaluation
  • Limit of detection calculation

A high-performance TLC scanner for rapid and accurate determination of radiochemical purity using thin layer chromatography. Bidirectional scanning automatically compensates for any isotope decay during scanning. The BGO detector provides high stopping power for single photon isotopes such as Tc99m. For PET use an alternative plastic scintillator is only sensitive to positrons, eliminating background due to other radio-active sources in the lab. Gina software provides real time feedback as the chromatogram builds up and powerful data analysis features.


GITA* moves the radioactivity detector along 1 trace from start to finish and goes to the next pre-programmed trace position and scans that trace with individual nuclide settings.

For ɣ-nuclides, GITA* uses a scintillation probe with a BGO crystal. Due to its density, BGO has a quite high stopping power for radiation and a reasonable energy resolution. BGO is mechanically stable and non-hydroscopic. Relatively small size and special shape enable a sophisticated design of the scintillation probe.

  • 5 mechanical collimators designed for the energy ranges of 0-60, 60-150, 150-250, 250-450, >450 keV.

  • Multiple traces can be displayed in 3-dimensional format.

  • Peak integration and evaluation can be performed manually or automatically.

Rita Star

β radioactivity detector for thin-layer-chromatography
Ultra-sensitive TLC analyser for nuclides such as 3h, 14c, 32p, 90y …

  • Very high sensitivity
  • Manual or automatic operation
  • 200 x 200 with up to 80 traces selectable
  • Live display of measurements

The RITA Star radioactivity thin-layer-chromatography detector is using a linear analyser detector, which is sensitive over the entire chromatogram trace from the start to the front. The entrance window can be open, for H-3-applications, or closed for any β­- or ­ β+ radiation emitting nuclides. Many ɣ-radiations emitting nuclides are emitting ­-radiation as well. The pure β-emitting nuclides can also be detected because they produce Compton electrons.

RITA Star has two simultaneous sensing electrodes: the delay line determines the location of the counted event; the pulse height of the counting wire is used for the electronic collimation.

Gabi Star

Radioactivity HPLC Flow Monitor
μ-processor controlled gamma spectrometer with built-in digital rate meter

  • Automatic energy calibration
  • High dynamic range
  • Operator selectable threshold settings
  • 2 simultaneous counting channels

The GABI Star stand-alone unit offers a keyboard and liquid crystal display for parameter dialog, entry and result presentation; a high voltage unit for manual or pre-set selection of the required detector operation; 2 simultaneous counting channels with 2 individually selectable energy thresholds each.

The 2 simultaneous counting channels with 2 individually selectable energy thresholds each, allow an individual counting window for a particular nuclide.
