Claims (8)
1. Sätt att analysera en gasblandning innehällande even-tuellt stofthaltigt fast material genom att avskilja och leda en viss mängd (2) gasblandning via en provtagnings-kanal (4) till analys, varvid tili den avskilda gasbland-ningen blandas en känd mängd vätska (5) för absorbering av gasblandningen i vätskan och varvid analyseringen utförs genom att analysera vätskan som absorberat gasblandningen, kännetecknat av att vätska (5) blandas tili den avskilda gasblandningen som leds tili analys omedelbart efter dess avskiljning och att nämnda avskilda gasblandning och vätska leds väsentligen tillsammans längs provtagnings-kanalen (4) för analys för renhällning av kanalen (4) frän eventuellt fast material och för att halla absorptions-tiden sä läng som möjlig mellan avskiljningen av nämnda gasblandning och analyseringen av vätskan som absorberat gasblandningen.
2. Sätt enligt patentkravet 1, kännetecknat av att för kontinuerlig blandning i vätskan av en avskild gasblandning (2) enligt en viss strömningsmängd mätäs tili provtagningskanalen kontinuerligt färsk, till sin strömningsmängd känd vätska för utförande av kontinuerlig analys.
3. Sätt enligt patentkravet 1, kännetecknat av att en viss vätskemängd cirkuleras en viss tid genom att äterinmata den tili provtagningskanalen nämnda tid för analysering av gasblandningsansamlingen.
4. Sätt enligt nägot av patentkraven 1-3, kännetecknat av att de eventuellt i vätskan olösliga fasta ämnena (8) och icke-absorberade gaserna (12) avskiljs (7, 10) frän vätskan (5) före dess analysering (14).
