Baseline Separation of
PAHs by HPLC, Using a
Pinnacle
II
™
PAH Column
✔
Fast analysis — resolve 16 target PAHs in less than 18
minutes!
✔
Excellent resolution — cross-linked C18 phase gives
baseline separation.
✔
Column-to-column reproducibility — we control the
entire manufacturing process: silica production -
column manufacture - final testing. You will see the same
outstanding performance from every Pinnacle
