- METHAMETER measures the concentration of CH4 in the outgas / exhaust gas
- Calculation of RQ (respiratory quotient), OUR (oxygen uptake rate) and CPR (carbon dioxide production rate) with SIAM industrial fermentation software
CARBOMETER
CARBOMETER to measure the concentration of the Carbon dioxide in outgas / exit gas of the bench-top fermentor and bioreactor system.
Connected to the outgas condenser (glass outgas condenser or peltier outgas condenser) of the MINIFOR laboratory fermenter – bioreactor, the CARBOMETER measures the concentration of the CO2 gas produced during the fermentation process.
SIAM SOFTWARE: RQ, OUR, CPR
SIAM, industrial fermentation software allows the possibility to calculate the RQ (respiratory quotient or respiratory coefficient) from the CPR (Carbon dioxide production rate) and OUR (Oxygen uptake rate, obtained from LAMBDA OXYMETER) during the fermentation process.

OUR, CPR & RQ
Respiratory quotient is defined as the number of moles of CO2 produced per mole of O2 consumed.
where,
RQ = Respiratory quotient or respiratory coefficient
CPR = Carbon dioxide production rate
OUR = Oxygen transfer rate
The RQ provides useful information about the metabolic activity and physiological conditions of the microorganism based on the relation between carbon dioxide production (CPR) and oxygen consumption (OUR) during fermentation process.
Monitoring the oxygen transfer rate (OTR) of aerobic animal cell, plant cell, fungal, yeast cell and bacterial culture reveals important information about the physiological state of the culture like substrate or oxygen limitation, diauxic growth and product inhibitions.
The carbon dioxide transfer rate (CTR) and respiratory quotient (RQ) obtained can be used to predict the biomass concentration, evaluate energetic efficiencies of growth, monitoring growth yields and controlling fed batch processes.
