can you comment about possible errors for a calculated flash point based on online composition analysis ?

As I understand, for mixtures, Prode software doesn't adopt a generic correlation but it solves phase equilibria condition and then it adds the contributes of individual flash points (for the different components in mixture) which are stored in Prode database,

this should give more accurate results (compared with a generic correlation)

my question is about accuracy of a flash point determination based on online composition analysis,

I do not know how accurate your on-line analyzer is (you should evaluate your self this aspect)

but I have compared several values of  Flash Points (of flammable mixtures) as calculated by Prode Properties with those available in literature and agreement is generally good (1-3 C) ,

see also this thread for a practical example

hoping this Helps

I confirm, for many mixtures errors are usually within a few degrees, 

for very non-ideal mixture you should consider phase equilibria as well

(to reduce errors, you may wish to recalculate BIPs with the included data-regression procedure)

thanks !

it seems the problem could be about the analyzer
