Equipment - Alltech Heliflex® AT-50ht Capillary Columns

Alltech Heliflex® AT-50ht capillary columns are a line of intermediate polarity low bleed fused silica GC columns manufactured and sold by Alltech Associates. They are specifically tested for bleed at 340C to allow for faster analysis at higher temperatures.

The stationary phase consists of 50% phenyl, 50% methylpolysiloxane. The columns are available in lengths of 15, 30 and 60m, internal diameters of 0.25, 0.32 and 0.53mm and film thickness of 0.15µm.

Applications include high boiling compounds.
They are similar to DB-17ht, Rtx-65TG, BPX-50 and CP-TAB-CB columns.
