Evaluation of the Developed Formaldehyde Detector

Crystalynne D. Cortez and Jennifer L. Santos
Abstract—The study was an evaluation of the formaldehyde detector that the proponents developed. The purpose of the study was to determine the consistency response of the device to the presence of formaldehyde. Specifically, the study aimed to expose and test the device with three different concentration of formalin. Small scale experimental method was used in the study where the gas sensor was placed inside an eight liter closed container. The gas sensor was exposed with formalin for 5 minutes and without formalin for another 5 minutes. Three different concentration of formalin were used in the experiment which were 1%, 5% and 10%. Three trials for every concentration were conducted. It was found that the device have constant response graphs to the three tests indicating that it was sensitive to formaldehyde of low to high concentrations. Furthermore, the developed formaldehyde detector worked properly within the limits set to it.

Index Terms—Gas sensor, consistency response, formalin exposure, formalin testing.
