DIACHROM BIOTECHNOLOGY GAS ANALYZER
DIA-GAS, analyzes the amount of oxygen uptake and carbon dioxide production in the outlet gas from your bioreactor or fermenter. Real-time monitoring of CO2 and O2 is a valuable tool for the measurement of cell growth within your fermentor vessels. Monitoring these changes can improve productivity by indicating the correct rates for oxygen flow and substrate feed. Using our Gas Analyser you can also make calculations of respiratory quotient (RQ), oxygen transfer rate (OTR), carbon dioxide transfer rate (CTR), as well as metabolic rate.
The gas analyzer will give you better indication of actual cell growth (live cell activity); it is easier to set up than a biomass monitoring probe and has a much lower cost than a mass spectrometer. It can be used with bacteriological fermentation and most cell culture work. DIA-GAS infrared gas analyzer can be used for measurement of the concentration of CH4, CO2, H2S and O2 in sample gases simultaneously . It is based on the single source two beams nondispersion infrared (NDIR) method for CH4, CO2, fuel cell method (ECD) for H2S and O2. The general application is landfill, anaerobic digestion and other fermentation Processes.
