Withdrawing of representative and reliable microsamples down to 1/100th mg is far from trivial, especially for extreme conditions such as high temperature and high pressure conditions or very corrosive media. The new Rapid On-Line Sampler-Injector presented herein was designed and set-up to largely extend sampling capabilities in hazardous media. It is largely used in our laboratory to measure vapour-liquid equilibria. It has a lot of applications, both in production (process control in petroleum, chemical, nuclear plants, etc.) and academic and industrial researches and development (laboratory instruments, pilot plants...).

Key words: Sampler -- fluid injector -- high pressures -- high temperatures -- chromatography -- on-line analysis
