Formaldehyde is an important organic compound used to make many materials and other chemical compounds. Its role in many industries varies from holding dyes onto fabrics, to assisting in the electroplating of metals. Formaldehyde is also used in biological preservation, drug testing, and photograph development. Each application uses different levels of formaldehyde and requires monitoring to optimize its given purpose. Formaldehyde is also a large consideration for human health. Due to its widespread use, there are regulations in place for formaldehyde limits within workplaces to avoid overexposure. Hanna Instruments offers a titration-based chemical test kit that determines the formaldehyde concentration in two ranges.
