Four-Channel Free Radical Analyzer

Features:

• Real-time detection using electrochemical microsensors
• Integrated system includes one temperature sensor, your choice of two additional sensors and a start-up kit
• Current measurement range from 300 fA to 10 µA (four ranges) permits wide dynamic range for detection
• Wide bandwidth allows recording of fast events
• Measure carbon monoxide from 10 nM to 10 µM
• Measure nitric oxide from < 0.3 nM to 100 µM
• Measure hydrogen peroxide < 10 nM to 100 mM
• Measure hydrogen sulfide
• Measure glucose
• Measure oxygen from 0.1% to 100%
• Isolated architecture allows Lab-Trax interface to simultaneously measure free radical and independent analog data (for example, ECG, BP, etc.) on any channel
• Four channel free radical detection
