FIELD: process engineering.
SUBSTANCE: invention relates to analytical instruments, particularly, to methods and means for increasing of reliability of gas analysers including gas analysers with photo-ionisation detector. Proposed device comprises the flask partially filled with hydrofluoric acid. Said flask is made of polymer permeable for hydrogen fluoride and placed in mixer with gas inlet and hydrogen fluoride outlet to detector ionisation chamber.
EFFECT: efficient cleaning without disassembly, safe and friendly cleaning.
