Abstract: The detections have been carried out to the nitrocellulose membrane (wet and dry condition) using a self-construction of polarized reflection spectroscopy. The measurement was done by illuminating the sample at an incident angle of 70° using a visible light source and then analyzing the reflected light off the sample received by the detector of spectrometer. From the investigation, the change of water content introduced to the membrane has been observed respects to the observation time. The water molecules present in or left the porous of membrane could be detected through the investigating of reflected intensities obtained from the measurement.
