Details

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 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 (i.e., ECG, BP, etc.) data on any channel

Real-time detection

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 new TBR4100. This optically isolated single-channel free radical analyzer has ultra low noise and independently operated channels.

Measure multiple species

TBR1025 is designed for use with WPI’s wide range of nitric oxide, hydrogen peroxide, hydrogen sulfide and oxygen sensors. 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.

Data acquisition

The TBR1025 analyzer utilizes PC-based data acquisition via our Lab-Trax interface; data traces are displayed and recorded in real-time. The LabScribe software 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.
