2480 Wizard2 automatic gamma counters Description The 2480 Wizard2® gamma counter is the premier system for counting high-energy gamma emitters, as well as low activity and environmental samples. The instrument has a maximum capacity of 1000 samples and its state-of-the-art radiation shield delivers optimal performance in gamma measurements. Standard features • Detector system consists of a thallium activated, sodium For In Vitro Diagnostic Use iodide crystal. The crystal height is 80 mm (3.15 in) and diameter 75 mm (2.95 in). The detector uses 4p counting geometry to ensure optimal counting efficiency of the sample. • Radiation shielding is present for the detector assembly and the conveyor. The detector assembly is surrounded by a minimum of 50 mm (2.0 in) of lead shielding above and below. The shielding against the conveyor is 75 mm (2.95 in) of solid lead. • Sample changer has a storage capacity of 100 racks (1000 samples, 3 mL tubes) or 54 racks (270 sample, 20 mL tubes). • Linear multichannel analyzer with 2048 channels. Dead time is 2.5 µs. • Counting efficiency is not highly dependent on sample volume. In 20 mL LSC vial, < 1%/mL change in relative counting efficiency for any nuclide in the range 0–20 m

2480 Wizard2 automatic gamma counters. • Radionuclide library consists of 51 nuclides, including the following: 125I 77Br 137Cs 123I 22Na 47Sc • Energy range is 15-2000 keV. • Maximum count rate is 10 million DPM (app. 8 million CPM) for 125I, with high activity mode max count rate is 30 million DPM for 125I. Dead time error < 1% to 2 million CPM. Rack and sample vial specifications • Sample tube specifications are shown in the table below. • Plastic sample racks of two different types can be used. They can be intermixed on the conveyor and are automatically identified. Racks have barcodes...

2480 Wizard2 automatic gamma counters. Quality control and regulations • Instrument Performance Assessment (IPA™) allows follow up of variable instrument parameters for quality control purposes. IPA automatically monitors data, evaluates monitored data for quality assurance and provides out-of-control warnings for nine detector parameters including: • Isotope main peak channel number • Background CPM in counting window • Relative detector efficiency • Detector resolution • Absolute detector efficiency • Window coverage • Detector stability probability • Measured CPM in counting window •...
