The production of radioactive labelled substances in general but especially for
nuclear medical diagnostic, therapy and research requires a thorough quality
control and certified radiochemical purity for every single batch.
Software
The miniGita scanner is controlled via a control software
running under Windows 98/2000/XP. Detailled evaluation is done using the
Gina Star TLC Software.
Performance
The miniGITA‘ s gamma detector is a special designed scintillation probe with a
V-shape BGO crystal mounted in Tungsten shielding. Resolution: raytest provides a wide range of Tungsten collimators to
optimize the resolution and sensitivity for any Gamma detection. Dynamic range: The miniGita provides a dynamic range of more than 4
orders of magnitude and a very good linearity over a wide range.
Detection
miniGITA is a thin layer chromatography scanner with a V-shape BGO crystal
detector specially designed for gamma and positron detection: 123I,
125I, 99mTC,
18F, 15O, 11C,
13N ...
Gamma / Positron detection
The crystal is having a 3 x 25 mm entry window and is 25 mm high. Arround the
crystal is a shielding of Tungsten with a outside diameter of 70 mm.
Advantages of the Crystal:
high sensitivity by BGO crystal scintillation probe and thin window entry.
excellent resolution by tungsten collimator and V-shape crystal.
low background by tungsten shielding and optimized crystal volume.
suitable for radiochemical purity determination.
raytest provides four specific collimators to suit to all the
nuclides:
