Details

A four channel free radical analyzer includes two sensors of your choice and start-up kit(s). To complete the system add a Lab-Trax data logger.

Real-time detection and measurement of a variety of redox-reactive species is fast and easy using the electrochemical (amperometric) detection principle employed in the TBR4100. Simply plug a sensor into the input channel on the front panel and select the current range. Poise voltage can be selected from a range of values tuned for optimal response from WPI sensors. An independent output for real-time monitoring of temperature is also included.

The analyzer utiliszes PC-based data acqusition via our Lab-Trax interface; data traces are displayed and recorded in real-time. The LabScribe software (formerly called Data-Trax) comes pre-configured for single or multiple electrode recording;  filters, gains, and smoothing are all set for optimal results. Data can be viewed making adjustments to smoothing and filter settings without affecting the original stored raw data. Electrode calibration from multiple concentration readings can be input into the software's Multipoint Calibration utility quickly provides a plot and slope calculation for electrode sensitivity determination.

  • Current measurement range from 300 fA to 10 µA (four ranges) permits wide dynamic range for detection
  • Wide bandwidth allows recording of fast events
  • Total galvanic isolation of channel inputs
  • Pre-adjusted selectable Poise voltage values for each type of WPI free radical sensor, as well as an adjustable voltage settings
  • Front panel mounted digital panel meters to monitor poise voltage and sensor current output on each channel simultaneously
  • Front panel BNC output connectors providing a low impedance voltage output signal, suitable for direct connection to any standard data recording device
  • Front panel input connectors designed to provide easy connection to the entire line of WPI free radical sensors
