Often theOVIs are low-boiling, lowmolecularweight
compounds that are difficult to retain and resolve on
capillary stationaryphases. Thick stationary films (3.0µm
and 5.0µm) often are used to achieve required separations
at a sacrifice in analysis time and the inability touse high
GCoperating temperatures. Restek is developing a new
stationary phase for confirmingOVIs, thatwill resolve
coelutingunregulated compounds from regulated solvents.
