The proSET CO2 /O2 off-gas analyzer provides real-time measurement of carbon dioxide and oxygen concentration of the bioreactor exhaust gas. The CO2 concentration is determined using a self-calibrating non-dispersion infrared sensor, while an electrochemical sensor monitors the oxygen concentration. Using this information, the user can continuously monitor metabolism and analyze cell growth parameters.
Control gases Carbon Dioxide Oxygen Range 0-10% (selectable range available) 0 – 50% Detector type Non-dispersion Infrared (NDIR) Electrochemical Accuracy ±5% ±1% (full scale) Response time 1.6 seconds 14±2 seconds Operating humidity 10-90% RH Calibration Auto-zero; default value present in factory (Built-in initialization) Air or calibration gas Sample delivery Inboard sample pump Sample connection 1/4” (6 mm) fittings for gas inlet/outlet ports Sample flow rate 300 - 1000 ml/min Flow meter range 100 - 1000 ml/min Power requirement 110 – 230 V AC, 50/60Hz Fuse rating 2 Amp Dimension (W x L x H) 355 x 230 x 190 mm
