WPC-9550 Automatic Low Background System
The WPC-9550 is a state of the art low background alpha/beta counting system. The system uses a proven gas flow proportional detector; a simple and efficient shield design, and a large area guard detector. The system will accommodate 50 (standard) to 100(optional) 2 inch diameter samples in standard planchets, up to 5/16 inch deep.

• 0.05 Alpha CPM Background; 0.45 Beta CPM Background
• Automatic 50/100 Sample Changer
• Ultra Thin Window
• Gas-PRO Fail-Safe Counting
• Window change in 4-5 minutes
• No lead lifting required
• No rear access required for maintenance

MDS Multi-detector Manual System
MPC-9604 Four Detector Subsystem
The MDS is a third generation multi-detector low background system for gross alpha/beta counting. The MDS is the very best system available for applications requiring high sample throughput and high sensitivity. Using one or more MPC-9604 four detector subsystems in parallel, the MDS can maintain very high sample throughput without sacrificing counting sensitivity.

• 0.05 Alpha CPM Background; 0.45 Beta CPM Background
• 4 to 64 Detectors per system
• Ultra Thin Window
• Gas-PRO Fail-Safe Counting
• Window change in 4-5 minutes
• No lead lifting required or rear access required for maintenance
• Loss free counting

ASC - High Speed Automatic Swipe Counter
Protean's ASC is the fastest swipe counter available. At 3 seconds or less per sample change, it can count a 50 sample stack of samples as fast or faster than a modern ultra-low background system. For many typical D&D requirements with release limits in the 20 DPM alpha/200 to 1000 DPM beta, the ASC is the most cost effective production system manufactured today.

• High speed sample change - < 3 seconds
• Small footprint ~ 25 x 25 inches
• Lightweight ~ 130 pounds
• Gas flow proportional w/Ultra-thin window
• Console Control
• Optional PC control with Vista FC
• Optional DP detector (no P-10 gas needed!)
• Optional GM detector
• Alpha background ~ 0.05 CPM
• Beta background ~ 35-45 CPM

MPC-2000 Desktop Alpha/Beta Counter
The MPC-2000 is the smallest and most versatile addition to an extensive line of gross alpha beta counting systems. It has modern control and interface options, a significantly reduced footprint, and a non-gas flow detector option.

• .05 Alpha CPM Background
• 40-50 Beta CPM Background
• Window or Windowless Operation
• Ultra Thin Window
• "No drop through" sample drawer
• Single finger drawer operation
• Loss free counting
• Gas-PRO Fail-Safe Counting
• Optional Non gas flow detector
• Same system runsFull featured digital MCA and gain stabilizer for ultimate stability

IPC-9025 Automatic Windowless System
The IPC-9025 is the only system available that offers reliable windowless operation, ultra-low background performance, light weight, and superb maintenance access in a single system.

• 0.05 Alpha CPM Background
• 0.4 Beta CPM Background
• Automatic 50/100 Sample Changer
• Ultra Thin Window optional
• 430 Pounds Installed
• Gas-PRO Fail-Safe Counting
• Loss free counting
• Window change in 4-5 minutes
• No lead lifting required
• No rear access required for maintenance

MPC-9900 - Component Alpha/Beta Counter
The MPC-9900 is a unique state of the art modular alpha/beta counting unit. It is designed to be built into large scale multi-detector systems that are optimized for alpha counting. The system can contain up to 64 modules, each independently controlled. The MPC-9900 module contains a full set of analog and digital electronics, including bias supply and Gas-PRO sensor. Low voltage power is supplied externally to the modules.
