Diesel Range Organics surrogate question...

[organicdude]

If there is anyone in here who runs Diesel Range Organics by FID, what surrogate do you use?

I am currently using n-Hexatriacontane as my surrogate; I am running the DROs on an FID on a DB-1 column.

I just wanted to see if anyone in here used something other than what I use as a surrogate.

Thanks

I use PTP (P-terphenyl) for dro 8015b method. Its available from chemservice out of Pennsylvania. OTP is also a suitable surrogate for DRO analysis.

We use 1-chloroctadecane for ours.
