Laboratory and industrial production process control requires a fast and accurate analysis of sample to allow optimum operating conditions to be set and maintained. This can apply equally to food and beverage production, pharmaceutical products or biopharmaceutical manufacturing systems for both cell culture and microbial applications. The speed and flexibility of our enzymatic laboratory analysers makes them ideal for quality control purposes. A printed result is obtained typically within 20 – 25 seconds from sample injection. New analytical assays are continually being developed; for example measurement of methanol from dimethyl dicarbonate (DMDC) preservation of juices and other beverages but also NAD and NADH for industrial control purposes.
Offer a simple, fast and flexible method for determination of key parameters in fermentation broths, cell culture media and other microbial applications.

The CO2 / O2 gas sensor analyses 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 fermenter 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 calculate respiratory quotient (RQ), oxygen transfer rate (OTR), carbon dioxide transfer rate (CTR), and metabolic rate.
SOLIDA infrared gas analysers can be used to simultaneously measure the concentration of CH4 and H2 in sample gases. This is based on the single source two beams non dispersion infrared (NDIR) method for CH4, CO2, and the fuel cell method (ECD) for H2S and O2.
The general applications are landfill, anaerobic digestion and other fermentation processes.

The Solida OD-CELL sensor performs online measurement of total cell density in solution. The sensor is based on optical density, which measures the turbidity of the cell suspension. The measurement is made at NIR (near-infrared) wavelengths so it is insensitive to changes in media colour.
All particles and molecules that absorb or scatter light at 880 nm will be detected, including living and dead cells and cell debris. This measurement is effective after inoculation, when cells are expanding quickly but concentrations are low, making permittivity-based readings less reliable.
