ASTM D8003 is a relatively new method for the analysis crude oil. It uses a HPLIS valve for sample injection to account for the combination of high pressure and heavy hydrocarbon carbon fraction.

What about the Agilent High Pressure Injection Device (G3505A)? http://cn.agilent.com/cs/library/applications/5989-8037EN.pdf . It looks like it may meet the specifications of the ASTM method. Not quite the same as the Transcendent PLIS but similar.
We have the Agilent HPLI and it works very well with LPG samples. Have not tried it on condensates or Canadian light crudes though.
