Multiplex® Non-Contact Optical Sensor
Optical Measurement of Polyphenols and Chlorophyll
Thanks to more than 15 years of research, Multiplex is now available for fast, easy, and non-destructive measurement of constitutive and induced polyphenolics and chlorophyll in plants. Multiplex uses fluorescence technology with multiple excitations to measure various compounds in berries skins, leaves, fruits and vegetables skins. Multiplex is the appropriate tool to easily monitor the phenolic maturity in grapes.
Monitoring of the Grape Phenolic Maturity
The phenolic maturity has a different time course than the technological maturity (pH, Brix...). It is important to monitor anthocyanins in red berries and flavonols and chlorophyll in white berries as they cant be strongly correlated to technical parameters and estimated indirectly. However, polyphenols measurements are expensive, labor and time consuming (chemical extraction, HPLC...) until now. Polyphenols measurements can now be realized with a fast and easy to operate instrument - the Multiplex.
With Multiplex the monitoring of the phenolic maturity becomes a common and simple practice.
Phenolic Monitoring Made Easy
A measurement with Multiplex takes less than a second by just pressing a button. The settings are easily configured through a user friendly interface on the touchscreen. The data is stored on a SD card and is also displayed on the LCD screen. The data can then be handled with the most common data presentation software. In its field portable version, Multiplex has a long life battery designed to keep measuring for an entire day and it can then be recharged in three hours.
