Tandem : Gas Analyser

Magellan Instruments : Reliability

The Tandem gas analyser offers you sophisticated CO2 and O2 gas measurement at a similar price to your other standard probes and sensors. Formerly the reserve of expensive equipment, you can now afford dedicated, individual, on-line monitoring and control of your processes. You gain the reliability and the flexibility required in your facility. At a time of squeezed capital budgets, the Tandem fits your needs.

How do you know whether you can gain from adding a Tandem to your process control equipment? If you are growing cells of any type in a bioreactor, you are likely to gain. To help you, the more of the statements below that apply to you, the more you can gain from gas analysis.

• I grow cells in a fermenter
• I take samples to make optical density, cell count or CDW readings
• I plot graphs of cell density or biomass, or calculate µ
• I want to reduce the number of samples I take
• I need to know glucose (or other substrate) uptake rates
• I need to know oxygen uptake rates
• I need to scale-up a bioprocess reliably to transfer to production
• I run a fed-batch process
• I run a continuous or steady-state process
• I want to know when my cells change their metabolism
• I want to reduce the amount of by-products produced by my cells
• I make ANY decision based on an off-line sample, e.g. induction, start of media or substrate feed, change of substrate, harvest etc.
• I need to characterise my process for validation work

There is a surprising amount of knowledge you can get about your bioprocess from the Tandem, and most installations are relatively simple. However, you must have a computer attached to your fermenter - this is the first step to improving your development times.
