Ir testing chemistry
WebJan 1, 1996 · This test recognizes the fact that "good" insulation will show a gradually increasing IR after the test voltage is applied. After the connections are made, the test voltage is applied, and the IR is read at two different times: Usually either 30 and 60 sec, or 60 sec and 10 min. WebMethods of Measuring Oil Chemistry INFRARED SPECTROSCOPY. Infrared spectroscopy uses a radiative source, a detector, and a computer to study the interaction of matter and light. Oxidation and nitration products appear as peaks in the IR spectrum between 1600 and 1800 cm-1. Sulfation products appear as peaks in the IR spectrum around 1120-1180 cm-1.
