TBR4100 四通道自由基分析儀
- Real-time detection using electrochemical microsensors
- Integrated system - includes sensors and start-up kit
- Measure up to 4 species in the same preparation
- Wide dynamic range for detection
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 four-channel free radical analyzer has ultra low noise and independently operated channels.
Measure multiple species
For use with WPI’s wide range of nitric oxide, hydrogen peroxide, hydrogen sulfide and oxygen sensors, the TBR4100 can measure four different species simultaneously in the same preparation. Simply plug a sensor into any one of the input channels 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.
Data acquisition
The TBR4100 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. Alternately, the Lab-Trax T series data interface can be used for providing simultaneous acquisition of Free Radical data along with other physiological data (ECG, HR, BP, etc.) as each of the four input channels has its own independent input amplifier, filters, and 24-bit converter.
