I don´t think that you will find reliable references for postprandial lipaemia because there are too many factors involved in this (composition of the meal, digestion, absorption, lipolysis by LPL, CETP activity, remnant uptake ....).
I agree with Michael on the difficulty of establishing a "normal" curve characteristics for postprandial lipemia. Apart from the characteristics of the patient (which are what we want to investigate), much depends on the composition and amount of fat (some items estimated at 70 g high absorption capacity), but also on the method of administration, because we have to approach that figure to see differences between patients unless the alterations are very severe. In our experience, measuring retinyl palmitate as a marker or isolating chylomicrons (probably small, but larger than VLDL), we can detect its presence until 10 hours after administration. In any case, I think that each group should define the response "Normal" studying a control group in which the components of interest to them are analyzed.
I leave some works done by us in postprandial lipemia
