Computer Controlled Gas Exchange Systems

Automated Multichannel Gas Exchange System Qubit Systems' multichannel gas exchange systems allow the researcher to make sequential gas exchange measurements from several sample chambers housing biological material. The chamber sequence, and the measuring period for each chamber is chosen in software. Channel numbers are available in multiples of four (4, 8, 12 etc). One channel is used for periodic checking of the reference gas, so that analyzer baselines can be monitored and data corrected for any drift. Testimonial: When purchasing a new gas exchange system for research purposes, I took a chance with Qubit systems; they claimed to produce a competitive system at almost half the price of those of more established companies. I am happy to say that I am entirely happy with my decision. I now have a reliable and versatile system that is just as accurate as the more expensive competition and, because it is modular, can be expanded as my needs evolve. Most importantly, I received outstanding service during all phases of purchase: conception, ordering, installation and continuing help. Bill Shipley, Département de Biologie, Université de Sherbrooke Features include the following: A wide range of gas analyzers are available for CO2, O2, CH4, N2O, CO, H2, etc. depending on system application Analyzers available with different ranges Calibration by simple calibration protocols in software Flow rate measured independently in each channel by a separate mass flow meter Different flow rates may be set for different samples, if required Rates of gas exchange are calculated automatically and displayed both graphically and numerically in software Data may be corrected automatically for dilution effects when respiratory quotient or photosynthetic quotient differs from 1.0. Both raw and corrected data are available for display and download as comma delimited files to Excel etc. Please contact us to discuss your application. We can custom design systems to meet your needs, and are happy to provide free consultation without any obligation to purchase.

 

Semi-automated Gas Exchange System Data acquisition performed via Logger Pro and LabPro Interface (4 or 8 Channels). Calculations are performed manually via a calculation template provided, depending on your application. The systems will perform real time measurements of several analyzers and sensors, display the data on screen and save to your computer for future analysis. CALL QUBIT FOR MORE INFORMATION
