Results are presented for on board sensing of the Gases NO, NO 2, SO 2 and CO optical fibre sensor was connected downstream of the Diesel Particle Filter (DPF) of a Fiat Croma and the measurements from the optical fibre sensors were recorded simultaneously using high specification reference instrumentation mounted in the boot of the : Elfed Lewis. Buffer solutions are needed as an indispensable tool for maintaining an accurate pH measurement. Buffer solutions are used as references points for calibration and adjustment of pH measurements to compensate for again and deterioration. pH buffer solutions are mixtures of weak acids and the salt of these acids with a strong base, or mixtures of [ ]. Our instrumentation and calibration techniques evolved from ALE to GAGE to AGAGE. With the inauguration of each new phase, measurement frequency and the number of analyzed species increased. Using gas chromatography (GC) with an electron-capture detector (ECD), the Atmospheric Lifetime Experiment (ALE) began operation in July (until about.
