“…The article covers sensing platforms, direct (spectroscopic) sensors, reagent-mediated sensors and discusses trends and future perspectives. Fiber-optic UV systems for gas and vapor analysis have been reviewed (5). The strong absorbance of vapors and gases in the UV region is advantageous and resulted in a compact detection system of good accuracy.…”

Applications and Optoelectronic Methods of Detection of Ammonia

“…Manap et al (2009) has shown that the ultraviolet measurement was highly selective as contamination gases were not identifiable. With the recent development of these systems, it is necessary that the performance ultraviolet optical components are analysed (Eckhardt et al (2007)). …”

A Sensitive and Portable Deep-UV Absorbance Detector with a Microliter Gas Cell Compatible with Micro GC

“…Previous research on BTEX detection was primarily focussed on the sensitivity of the sensor and mostly an individual BTEX molecule was tested. Eckhardt et al [21,22] developed a detector with an aluminium-coated HCW (length, 1 m and diameter, 1 mm) as a gas cell, deuterium lamp (30 W) as UV source, and CCD-based spectrometer as a UV detector. The setup was coupled with GC and tested for detection of aromatics compounds like ethylbenzene and bromobenzene.…”
