Carolina ChemKits®: Smartphone Spectroscopy

Item # 840262

Connect students and science through their smartphones while introducing them to visible light spectroscopy fundamentals. In this lab, students measure the transmittance of light through standard solutions of Red Dye No. 40 with a smartphone, a color analyzer application, the Carolina® Spectroscopy Chamber, and a spectrophotometry technique. Using the collected data, students create a Beer-Lambert plot to determine the concentration of the food dye in popular powdered drink mixes.

  • Overview

    Transform a smartphone into a spectrophotometer with the Carolina® Spectroscopy Chamber!

    The Carolina® Spectroscopy Chamber, like its traditional counterpart, is designed to allow light to pass through a sample in a clear colorless tube. The smartphone application analyzes the light. Students then convert that collected data to absorbance or transmittance and create Beer-Lambert calibration curves to determine the concentration of food dye in popular powdered drink mixes.

    Not only are students engaged in science using a device with which they are highly familiar, but they also learn how a spectrophotometer works on the inside before moving on to a delicate, more expensive instrument. Works with both Android™ and iOS® devices. Use the color analyzer app of your choice; no special optical glass tubes are required. Materials are sufficient for 30 students working in groups of 3.

    Note: Materials needed but not supplied include smartphones, color analyzer applications, and glassware for serial dilutions.
