Product Description

The Quantulus GCT 6220 is a liquid scintillation counter for ultra low-level sensitivity, in a lighter benchtop footprint to fit any lab. It has extremely high sensitivity and unmatched detection of low level Alpha and Beta radioactivity.

The Quantulus GCT 6220 liquid scintillation counter is a fully loaded benchtop instrument with unsurpassed performance for measuring man made, cosmic and other natural radionuclides. Patented GCT technology combined with BGO guard background reduction accurately measures to near-background levels. Proprietary Dual PSA Discriminator and PSA Histogram improves accuracy for mixed and unknown samples.

Exclusive Standard Features

• Patented Bismuth Germanium Oxide (BGO) and Guard Compensation Technology (GCT) enhances discrimination against background yielding the highest E²/B values available in a multipurpose liquid scintillation counting system
• TR-LSC (Time-resolved Liquid Scintillation Counting) for high sensitivity, low background liquid scintillation counting
• QuantaSmart^™ Software a robust multitasking, easy networking environment with unlimited assays in a secure multiuser environment
• Alpha Beta Separation uses Dual PSA Discriminator and PSA Histogram to improve accuracy for mixed and unknown samples
• SpectraWorks 2 spectral analysis package that determines optimal counting regions, and calculates figure of merit automatically
