Radiometric Detectors 

The Tri-Carb 4810TR liquid scintillation counter is ready to go for basic research and CPM/direct DPM applications.

Exclusive Standard Features

• 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
• SpectraWorks 2 spectral analysis package that determines optimal counting regions, and calculates figure of merit automatically
• 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)
• Operational-status LED indicator for clear assay status updates at a glance

Additional Standard Features

• Luminescence Detection Reporting percent luminescence is flagged on printout to alert user of possible sample problems
• Direct DPM determines single-label DPM in any cocktail without the use of quench standards
• 15 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

Physical data

• Dimensions H/W/D 18.5 /40.5/32 in (47/103/81 cm)
• Weight 477 lb (217 kg)
• Electrical requirements 100-240 Vac 50/60 HZ 3-prong grounded plug

Typical performance data

• Energy range: 0-2,000 keV
• Efficiency, Normal Count Mode (minimum acceptable):
  ³H (0-18.6 keV): 60%
  ¹⁴C (0-156 keV): 95%
• Observed Background, Normal Count Mode (average):
  ³H (0-18.6 keV): 17 CPM
  ¹⁴C (0-156 keV): 26 CPM
• Figure of Merit (E²/B), Normal Count mode:
  ³H (0-18.6 keV): 180
  ¹⁴C (0-156 keV): 380

Note: The efficiencies, backgrounds, and E²/B values for the Normal Count Mode were determined using Revvity sealed large vial glass standards set P.N. 6008500 verified with NIST standard activity.

Option Package

• Replay reanalyzes sample counts without recounting samples and
• Varisette^™ sample cassette for intermixing vial sizes without special adapters
