Stratophase’s innovative optical microchip technology is small enough and flexible enough to fit anywhere into your production process that requires real-time, in-line status monitoring.
What do we offer?
The system is robust and non-invasive, meaning it does not influence reaction conditions and can be cleaned ‘in place’ using standard industrial techniques.
Several sensors can be optically networked to provide an integrated, multi-point monitoring solution. SpectroSens technology works by monitoring changes in the refractive index (RI) properties of the reaction medium, simultaneously measuring temperature changes.
What can RI and temperature tell you about your process?
Using our optical microchips you can monitor the status of your process in real-time, such that the optimal conditions for production can be characterised and used to alert the process operator of deviations from the ideal range. After calibration there is the potential to monitor changes such as microbe growth, nutrient concentration change, product concentration, dissolved solid concentration, crystallisation amongst other parameters.
How does the Stratophase solution work?
The Stratophase control unit is the brains of our monitoring system. It emits light which can be carried up to 50 km to the sensor measurement head via standard telecoms optical fibre. Changes in wavelength occur at the optical microchip surface, this information is carried back down the same optical fibre to the control unit for analysis. The unit tracks the refractive index and temperature of the liquid and presents the data in a number of user-friendly formats, including visual display, CSV data files, OPC DA, 4-20mA signal. This information is provided in real-time making it easy to make rapid process decisions based on up-to-date status data.

What are the advantages?
Apart from the ability to monitor process status in-line and in real-time, the Stratophase monitoring solution has several other advantages.
They can run in dynamic temperature environments, accurately reflecting the temperature of the product.
As the sensor heads are passive devices requiring no direct power, they do not influence the temperature of the reaction media are intrinsically safe for use in explosive environments.
Finally, the optical nature of the system means that the readings obtained are not corrupted in high noise environments, and can be distributed accurately over large distances without any loss in quality.
What are the options?
Our control units come in two versions — bench top or rack mounted units. The bench top solution is perfect for product development labs and small scale processes, whereas the rack mounted units are best suited to large scale industrial settings such as those employing PAT. Similarly, we produce a variety of sensor measurement heads designed for the specific needs of the application in question. This includes a pipeline format for use in continuous flow processes, as well as an insertion probe format for reactor vessels of all sizes. The control units and measurements heads can be integrated in whichever combination is required.
