Alternative Method of Spectroscopy of Alkali Metal RGB

Authors: Ricardo Gobato, Manuel Simões Filho

Spectroscopy is a technique for collecting physicochemical data through the transmission, absorption or reflection of incident radiant energy in a sample. In this work we used a didactic and alternative method for spectroscopy. Our work is used in common low cost and easy access devices that have a CCD reader. The idea is a set of devices, such as a cell phone, which contains an optical CCD reader, where these equipment materials, materials, compounds, simplifying the image obtained by these optical devices, analyzed and characterized. Our technique consists of decoding of the pixels of the .bmp images, decoding and quantifying their RGB color channels. These images were obtained from shooting flames produced by alkali metals, lithium, sodium, potassium, rubidium and cesium. We conclude that it is possible to do a spectroscopic analysis using our technique.
