Revvity LSC Counter Quantulus GCT

With its extremely high sensitivity and low-level Alpha and Beta detection, the Quantulusâ„¢ GCT 6220 is the ideal solution for even the most demanding environmental applications.

In the Quantulus GCT 6220, a unique Bismuth Germanium Oxide (BGO) detector guard completely surrounds the sample. The BGO guard translates external gamma radiation to the photomultiplier tubes, allowing the externally generated counts to be discounted, further reducing background. The BGO guard works in conjunction with patented Guard Compensation Technology (GCT) background reduction to further lower the instrument background, enhancing sensitivity to accurately measure near-background sample activity. This sophisticated technology is designed to use ordinary glass or plastic vials so counting is easy and inexpensive.
