Abstract

We report here the detection of gaseous ammonia with the methylated and ethylated forms of dyes that were originally developed in a CEC programme to produce spectral changes in the near infrared (NIR) region on exposure to ammonia. In contrast with pH sensitive dyes, these new dyes are suited for the detection of gaseous ammonia both in moist and dry air. The dyes have been immobilised in the cladding material of commercial available plastic-clad silica fibres and the evanescent detection of gaseous ammonia was achieved with the limit of detection in dry air being 100ppm for 2m length of the sensing fibre.
