  • Publication number: 20180052101
    Abstract: The present invention discloses an apparatus and a method for measuring components in fluidic samples in a non-invasive fashion using Infrared (IR) transmission spectroscopy. Fluidic samples are sealed in flexible IR-transparent bags that are then fixed on a supporting bed. The supporting bed is then mounted between the front and back plates of the apparatus so that the bag is squeezed by two IR transparent windows from opposite directions until the windows contact the spacer sheet mounted on the back plate. The thickness of the spacer sets the gap distance between the two windows and thereby sets the optical path for the measurement in the transmissive mode.
