Overview
The MPC-1000-GFW and MPC-100-GFL single detector manual counters are the most versatile, high-performance, low background counters available. These counters provide new labs a cost effective entry into low background alpha/beta counting until sample volumes grow larger and justify either multi-detector systems or automatic counters. The MPC-100-GFL with a windowless gas flow detector delivers higher efficiencies for projects involving alpha emitters and higher activity low-energy beta emitters. Each counter has the ability to program routines and QC charts on a PC running the included DUO Express software, then transfer the routines to the instrument using a direct-connect PIC Link cable.
MPC-1000-GFW Part Number: 105-1000-W
MPC-1000-GFL Part Number: 105-1000-WL
