The Quantulus GCT 6220 is a liquid scintillation counter for ultra low-level sensitivity, in a lighter benchtop footprint to fit any lab. It has extremely high sensitivity and unmatched detection of low level Alpha and Beta radioactivity.
The Quantulus GCT 6220 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 to near-background levels. Proprietary Dual PSA Discriminator and PSA Histogram improves accuracy for mixed and unknown samples.

Figure of Merit (E2/B), Normal Count Mode: 3H (0-18.6 keV): 400 14C (0-156 keV): 1,0000
Figure of Merit (E2/B), Super Low Level Count Mode (ULLCM): 3H (0-18.6 keV): 800 14C (0-156 keV): 6,000
Observed 3H Performance with 10 mL H2O in 10 mL Ultima Gold LLT and Plastic Vials with GCT high E2V2/B > 131,000 or more
Observed 14C Performance for 11 mL Bioethanol Samples in 9 mL Ultima Gold F in Plastic Vials with GCT high: E2V2/B > 1,030,000 or more
Note: The efficiencies, backgrounds, and E2 /B values for the Normal Count Mode were determined using PerkinElmer sealed large vial glass standards set P.N. 6008500 verified with NIST standard activity. Super Low Level Count Mode Values are determined using low level sealed large glass standards P.N. 6018914 verified with NIST standard activity. No maximum is specified for background.
Radiometric detection (RAD) is one of the most proven techniques for molecular quantitation around – and it’s still indispensable for key applications. Here’s the state of the industry, and where it’s headed.
