Methods, Standard Deviations, Relative Error (Biomass) and Error Types Typically for Methods/Devices Typically used for Quantitative Evaluation of Fed-Batches
| Device/Method | Relative Error | Type of Error | Range | Unit |
|---|---|---|---|---|
| Feed balance | 1 | Absolute error | 0–35.000 | (g) |
| Base balance | 1 | Absolute error | 0–35.000 | (g) |
| Reactor balance | 1 | Absolute error | 0–35.000 | (g) |
| O2 off-gas analysis paramagnetic | 0.02 | Relative error | 0–26 | (%) |
| CO2 off-gas analysis infrared | 0.01 | 0.1% absolute error on full scale 0–10% | 0–10 | (%) |
| MFC_Air thermal mass flow meter | 0.035 | Relative error | 0–40 | (l/min) |
| Biomass quantification e.g.: dryweight, capacitance | 2% (dry weight, for s = 4 %) and 4 replicates according to Equation 20), or 8% (capacitance) | Relative error | >0.1 | (g/l) |
