- Abstract:
- Tunable Diode Laser Absorption Spectroscopy has been applied to the realization of an instrument for the non-invasive contactless measurement of gaseous oxygen concentration inside sealed food containers. The device performs in-line measurements on samples which are passing on a conveyor belt and has been applied to the measurements on mozzarella cheese bags sealed in modified atmosphere, in which the target oxygen concentration is required to be below 5%. We describe the realization, calibration and validation of the device.
