Development of a toluene detector based on deep UV absorption spectrophotometry using glass and aluminum capillary tube gas cells with a LED source

Khan, Sulaiman; Newport, David; Le Calvé, Stéphane (MDPI, 2019)

A simple deep-ultraviolet (UV) absorption spectrophotometer based on ultraviolet light-emitting diode (UV LED) was developed for the detection of air-borne toluene with a good sensitivity. A fiber-coupled deep UV-LED was ...
Low-volume PEEK gas cell for BTEX detection using portable deep-UV absorption spectrophotometry

Khan, Sulaiman; Newport, David; Le Calvé, Stéphane (Elsevier, 2020)

Monitoring of indoor air quality by detecting individual airborne pollutant is essential for maintaining a healthy indoor environment. UV absorption spectrophotometry coupled with gas chromatography offers a reliable, ...
