A method for detecting for a presence of a toxic element in a sample includes emitting UV light from an UV-VIS LED illuminator onto a sample as incident light. Capturing a portion of the incident light being reflected from the sample using a frinGOe interferometer and converting the reflected light to an interferogram spectrum. Collecting the interferogram spectrum using a camera. Retrieving the interferogram spectrum from the camera and transforming it to absorption wavelength spectrum using Fourier transformation via a microcontroller. Comparing and normalizing the absorption strength peak wavelength using the microcontroller. Comparing the normalized absorption strength peak wavelength spectrum with stored allowable toxic chemical absorption strength peak wavelength thresholds. Sending a message indicating that the sample is safe or not safe to use to a LCD screen and a speaker based on the comparison between the normalized absorption strength peak wavelength spectrum and the stored allowable thresholds.
