“Comparative Assessment Of Glucose Determination In Blood Using Fabricated Colorimeter And Strip-Based Commercial Glucometer” (original) (raw)

Present approach is an effort to develop a handy, less in cost, less power consuming and compact, colorimeter for quantitative colorimetry with diminished detector size. A relatively small electric current with improved power sensitivity photosensitive device: MORICA MP series-MH-208 photodiode has been used to diminish size of the assembled colorimeter. This detector has good signal to noise ratio and hence can sense very low level of intensity. The major challenge in assembling these portable analytical devices is to reduce detector size. Common photo resistor or other newly electronic component including silicon photodiodes can be used as detector in portable colorimeters. In the recent colorimeters, output current is amplified by connecting the detectors to operational amplifiers. Although the reports in the literature reveal a great deal of advances on colorimeters, still efforts are needed for simplifying the colorimeter for analytical applications in field conditions for esti...
