A system for generating Ultra-Violet (UV) images and measuring the permeation or diffusion of one or more substances through a membrane, the system including: a. a cell comprising of: i. a first and second window through which UV and visible (VIS) electromagnetic radiation can pass; and, ii. a membrane support means configured to hold a membrane ; b. the system further comprising: i. a UV-VIS light source; and, ii. a UV-VIS CMOS detector; characterised in that : c. the first and second windows are located on respective opposing walls of the cell and are parallel to each other; d. the membrane support means is positioned inside the cell and transverses at a right angle the first and second window, such that the cell is partitioned into a first and second chamber; e. the first and second windows being partitioned between the first and second chamber; f. the first chamber is configured to hold a fluid; g. the second chamber is configured to hold a sample; h. the UV-VIS light source is located adjacent to the first window; and, i. the UV-VIS CMOS detector is located adjacent to the second window; such that, j. UV-VIS electromagnetic radiation from the UV-VIS light source passes in a straight path through both the first and second windows and chambers, respectively. a. a cell comprising of: i. a first and second window through which UV and visible (VIS) electromagnetic radiation can pass; and, ii. a membrane support means configured to hold a membrane ; i. a first and second window through which UV and visible (VIS) electromagnetic radiation can pass; and, ii. a membrane support means configured to hold a membrane ; b. the system further comprising: i. a UV-VIS light source; and, ii. a UV-VIS CMOS detector; characterised in that : c. the first and second windows are located on respective opposing walls of the cell and are parallel to each other; d. the membrane support means is positioned inside the cell and transverses at a right angle the first and second window, such that the cell is partitioned into a first and second chamber; e. the first and second windows being partitioned between the first and second chamber; f. the first chamber is configured to hold a fluid; g. the second chamber is configured to hold a sample; h. the UV-VIS light source is located adjacent to the first window; and, i. the UV-VIS CMOS detector is located adjacent to the second window; such that, j.
