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
  • Enhanced IPA (Instrument Performance Assessment) monitors performance metrics for the life of the instrument
  • Replay reanalyzes sample counts without recounting samples
  • Dynamic color correction ensures accuracy of tracking lower energy sample spectra over a wide quench range
  • Auxiliary Spectrum Memory stores rejected events for future analysis
  • Bi-directional sample conveyer with a capacity of up to 408 (20mL vials) or 720 (4 or 7 mL vials)
  • Varisette sample cassette for intermixing vial sizes without special adapters
  • Operational-status LED indicator for clear assay status updates at a glance

Additional Standard Features

  • Luminescence Detection flags percent luminescence to alert user of possible sample problems
  • Luminescence Correction adjusts for chemiluminescence interference
  • Direct DPM determines single-label DPM in any cocktail without the use of quench standards
  • Temperature Control maintains optimum conditions for a variety of samples
  • 60 Quick Count protocol flags with the flexibility to define unlimited assays
  • Fold-away ergonomic arm adaptable to enter data either sitting or standing
  • Built in Computer with Windows 10 Operating System
