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
