ES AP is a special amino packing for the analysis of hydrocarbon classes especially in Diesel fuels. It is characterized by the following properties:
Optimal separation of paraffines from aromatics with a resolution of RS
= 8 - 9.
Tetraline eluates always within the family of monoaromatics.
and fluorene eluate clearly ibefore the switch time, which will be calculated
retention times of dibenzothiophene and 9-methylanthracene.
Diphenylmethane and fluorene eluate together with or earlier than dibenzothiophene,
