The CHErenkov/Scintillation Separation experiment (CHESS) has been used to demonstrate the separation of Cherenkov and scintillation light in both linear alkylbenzene (LAB) and LAB with 2 g/L of PPO as a fluor (LAB/PPO). This is the first successful demonstration of Cherenkov light detection from the more challenging LAB/PPO cocktail and improves on previous results for LAB. A time resolution of 
ps FWHM results in an efficiency for identifying Cherenkov photons in LAB/PPO of 
and 
for time- and charge-based separation, respectively, with scintillation contamination of 
and 
%. LAB/PPO data is consistent with a rise time of 
ns.
