I. Reimann et al., APPLICATION OF THE PHOTOIONIZATION DETECTOR FOR THE DETERMINATION OF ETHANOL IN AQUEOUS-SOLUTIONS AND HUMAN BREATH, Fresenius' journal of analytical chemistry, 353(2), 1995, pp. 206-210
A determination of ethanol is described, which is based on a purging s
ystem in conjunction with a photoionization detector. With that system
a fast and reliable determination of ethanol in aqueous solutions is
possible. The system has been used for the analysis of wine. The 3 del
ta-detection limit has been 0.005% ethanol, the relative standard devi
ation 4.8 to 6.0% and the time constant of the entire analytical syste
m 20 s. The photoionization detector has been also applied to the anal
ysis of artificial and genuine human breath. A comparison with gas-chr
omatography and non-dispersive IR-detection has been proven the reliab
ility of results.
