A sample consisting of toluene? and you are looking for solvents within the toluene? or a sample containing toluene and you wish to separate the toluene from the sample?

If the sample is fully dissolved into a non-polar solvent then a less then .25mL sample solution should equilibrate in 15 min or less.
In water solution I would suggest that 8 minutes or less will be adequate.
I would use a temperature of 80C to 85C.
