Radiometric Detectors 

he Tri-Carb 5110TR liquid scintillation counter is a fully loaded premium instrument capable of more accurately detecting Ultra Low Level counts in mixed and unknown samples using proprietary Dual Phase Separation and PSA Histogram technology.

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
• Alpha Beta Separation uses Dual PSA Discriminator and PSA Histogram to improve accuracy for mixed and unknown samples
• ULLCM (Ultra Low Level Count Mode) with Pulse Amplitude Comparison (PAC) decreases the component of background produced by optical crosstalk, increasing system sensitivity (E²/B) to a factory test minimum of 500 for ³H and 1,400 for ¹⁴C
• 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 Correction adjusts for chemiluminescence interference
• Direct DPM determines single-label DPM in any cocktail without the use of quench standards
• 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

• Dimensions H/W/D 18.5/40.5/44 in (47/103/112 cm)
• Weight 523 lb (238 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): 63%
  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): 360
• Figure of Merit (E²/B), Ultra Low Level Count Mode (ULLCM):
