The Quantulus GCT 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 near-background sample activity.

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
• Time-Resolved Liquid Scintillation Counting (TR-LSC) – 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 Pulse Shape Analyzer (PSA) Discriminator and 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 Instrument Performance Assessment (IPA) - 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 – Has a capacity of up to 408 (20 mL 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
