4,4'-MDI
Posted: Thu Nov 03, 2011 9:31 am
Hello,
have you any expierience in determination of 4,4'-diphenylmethane diisocyanate in workplace atmosphere using GCMS system? I mean kind of column, approx. temperature for which this compound can be eluted, some problems with thermal degradation etc. Have you any suggestions according to choice of sorbent material for capture it from air? What about desorption besides of thermal process (CS2 would be OK)?
Thank you in advance
