In Aj. Gates lab we have been experimenting on using an alternative way to measure the concentration of unknown samples. A spectrophotometer is traditionally used to measure the absorbance of a solution at a particular wavelength as concentration is directly proportional to absorbance. Aj. Gate has been doing research on a greener method that doesn't use expensive equipment and may be able to analyze concentrations on site rather than bringing the solutions back to the lab. We are currently doing are experiment on seeing if an Iphone camera is effective enough to accurately measure the concentration of unknown protein solutions.
In today's modern world, camera phones are everywhere. With smartphones, the modern phone is packing everything we could possibly need and want into a tiny but powerful device. Using an Iphone for analysis can be a breakthrough in analytical chemistry in finding a more convenient way to analyze data. With a camera phone, samples can be measured at the site, making it easier for an on-field chemist. The technique also uses uL instead of mL which benefits in producing much smaller amounts of solution and waste. The camera takes a pallete full of samples to be analyzed at the exact same time. This adds for more accuracy as their is much less time wasted for the solution reacting with the indicator reagent as the picture is taken at the same time for all of the unknown samples and standards. The modern smartphone becoming norm in the chemical field would provide more accuracy in getting the correct concentration.
Our research this week involves Brenna, and I to measure the protein concentration of beauty drink, fish sauce, soy sauce, and chicken broth. The solutions will be measured by placing the samples in a palette in a black box with a bright white light under the palette to provide the truest color of the solutions while minimizing the amount of reflection. We have decided to use the red RGB intensity number to quantitate the solutions as the green and blue intensities have proven to be less linear due to the absorbance of those colors from the Folin reagents use to give a bluish color. The goal of the experiment is to see that a phone camera can be just as effective as a spectrophotometer.
