NOVELTY – The cell has a main tube provided with an upper opening, a lower opening, a radiation source, a detector circuit, and a reflective material sheet, where a solution to be analyzed is placed inside the main tube. The main tube is made of a rigid material selected from graphite polytetrafluoroethylene, polyvinyl chloride, metal and glass. The solution in main tube consists of bisphenol epoxy, ethanol, cumene hydroperoxide, salicylic acid and cyclohexanol. USE – Cell for photometric measurement. ADVANTAGE – The main tube is provided with an upper opening, a lower opening, a radiation source, a detector circuit, and a reflective material sheet, where a solution to be analyzed is placed inside the main tube, and thus ensures efficient photometric measurement cell. DETAILED DESCRIPTION – An INDEPENDENT CLAIM is also included for a method for obtaining photometric measurement. DESCRIPTION OF DRAWING(S) – The drawing shows a schematic view of a photometric measurement cell.
