Formaldehyde in an Indoor Environment
Wall and floor materials used in houses may contain residual formaldehyde, which may be dispersed throughout the house as a vapor. It is important to measure the concentration of this formaldehyde. Formaldehyde concentration was measured at several positions in a new house using a combination of solution collection (in water) and acetyl acetone colorimetry.

UV-VIS Spectrophotometer
This instrument performs qualitative and quantitative analysis using the property that chemical substances absorb light at specific wavelengths. Formaldehyde is quantified using a light of wavelength of 412 nm.
