History of Pulse Oximetry Before the Pulse-Oximeter the only way to measure SpO2 was by using a painful arterial blood gas which took a minimum of 20-30 minutes to view the result. In 1974 Takuo Aoyagi a Niigata University student disclosed his first Pulse-Oximeter for the use of pilots in World War 2. He set about searching for a non-invasive way of monitoring arterial blood oxygen saturation. Nellcor’s pulse oximeter was put on the market in 1983 and this used his theory developed in 1974. By

Abstract-Timur Solid phase extraction is a sample preparation technique that overperform liquid /liquid extraction in its efficiency‚ labor intensity and waste disposal. The purpose of this lab is to learn how SPE can be used to identify trace amounts of Vanillin. Stock solution of vanillin in water with concentration of 50 ppm was prepared. Four solutions with concentration of 5 ppm‚ 1 ppm‚ 0.5 ppm and 0.1 ppm were made from stock solution. UV-Vis spectra of standard solution was recorded at 229

A transistor is a semiconductor device used to amplify and switch electronic signals and electrical power. It is composed of semiconductor material with at least three terminals for connection to an external circuit. A voltage or current applied to one pair of the transistor’s terminals changes the current flowing through another pair of terminals. Because the controlled (output) power can be higher than the controlling (input) power‚ a transistor can amplify a signal. Today‚ some transistors are
