The Tri-Carb 4910TR liquid scintillation counter provides high performance and flexibility for multi-application and multi-user laboratories detecting radioactivity in life science research, environmental monitoring and/or health physics assays. Optional Packages are available for High Sensitivity Counting of low activity samples and Alpha Beta Separation for unknown or mixed samples.

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
  • 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
  • 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
  • 30 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)
  • Dimensions with temperature control H/W/D 18.5 /40.5/32 in (47/103/81 cm)
  • Weight 477 lb (217 kg)
  • Weight with temperature control 523 lb (238 kg)

Additional Options

  • Luminescence Correction removes sample counts induced by luminescence in the sample
  • High Sensitivity Counting lowers background levels for improved instrument sensitivity
  • Enhanced IPA (Instrument Performance Assessment) monitors and reports eight key counting performance metrics for quality assurance and warns of significant changes
  • Alpha Beta Separation via PSA Histogram and Dual PSA Discriminators improves accuracy for mixed and unknown samples containing isotopes with overlapping energies
