Hello,

someone knows what means T.DBL usually I take the defaulf mode 1000 ,but 1000 what? minutes ,seconds,AUFS?

thanks

T. DBL means the time peak width in the integration parameters table doubles. This is used for isothermal analysis where the peak widths get broader as a function of retention time, so for temperature programmed runs the value is set to 1000 minutes so the peak width parameter remains a constant.

Thanks you for so quick response!

and about the DRIFT and SLOPE?
I know that SLOPE have a relation with base line correction for peak area calculation but I don't have idea about DRIFT meaning.

Could you please tell us in which system you find these parmeters; different packages (integrators or software) may use the same terms with slightly different signification.
Slope and Drift remind me of Shimadzu integrators parameters.
In most systems, slope refers to the value of the first derivative of the signal that triggers start en stop of peak integration.
Drift may refer to a preset value that is substracted from slope (for instance to prevent an upwards baseline drift from beeing integrated even without peaks).
Again, these terms may differ from a brand to another; you should refer to the documentation of you system (and/or the help section if it is a software).
