About
Paper Analytical Device for Quantifying Iodine in Fortified Salt A paper analytical device (PAD) for use in low-resource settings to test for the presence of iodine in salt. To test the salt, a solution of the salt and water is dropped onto the PAD in several reaction zones. The pad is quantitative in the range of 0.95-15 ppm iodine with a precision of 0.5 ppm iodine (as mg iodine per kg salt). The PAD may be interfaced with cell phone camera technology to allow refined quantification by colorimetry.
