Formaldehyde sensor using non-dispersive UV spectroscopy at 340nm

Davenport, John; Hodgkinson, Jane; Saffell, John R.; Tatam, Ralph P. (International Society for Optical Engineering; 1999, 2014-05-22)

Formaldehyde is a volatile organic compound that exists as a gas at room temperature. It is hazardous to human health causing irritation of the eyes, nose and throat, headaches, limited pulmonary function and is a potential ...
A measurement strategy for non-dispersive ultra-violet detection of formaldehyde in indoor air: Spectral analysis and interferent gases

Davenport, John; Hodgkinson, Jane; Saffell, John R.; Tatam, Ralph P. (Institute of Physics, 2015-12-14)

We have conducted an extensive review of published spectra in order to identify a region with potential for detection of formaldehyde in indoor air. 85 chemicals and chemical groups common to the indoor environment were ...
Noise analysis for CCD-based ultraviolet and visible spectrophotometry

Davenport, John; Hodgkinson, Jane; Saffell, John R.; Tatam, Ralph P. (Optical Society of America, 2015-08-17)

We present the results of a detailed analysis of the noise behavior of two CCD spectrometers in common use, an AvaSpec-3648 CCD UV spectrometer and an Ocean Optics S2000 Vis spectrometer. Light sources used include a ...
UV spectroscopic instrumentation for formaldehyde detection in the indoor environment

Davenport, John (Cranfield University, 2014-01)

The aim of this project was to assess the feasibility of using UV spectroscopy for a simple detection system for formaldehyde gas in the indoor environment. Formaldehyde gas is hazardous to human health causing irritation ...
