Equipment - Alltech Heliflex® AT-1ht Capillary Columns

Alltech Heliflex® AT-1ht capillary columns are a line of high temperature low bleed, highly inert, non-polar fused silica GC columns manufactured and sold by Alltech Associates. They are specifically designed for achieving faster analysis times for high boiling compounds. They are individually bleed tested at 380°C.

The stationary phase consists of 100% dimethylpolysiloxane. The columns are available in lengths of 15, 30 and 60m, internal diameter of 0.25mm and film thickness of 0.1µm.

Applications include high boiling compounds, waxes, crude oils and triglycerides.

They are similar to 007-1, CP-Sil 5CB, DBTM-1, DB-1ht, HPTM-1, HP-101, OVTM-1, RSLTM-150, RSL-160, RtxTM-1, SE-30TM, SPBTM-1, SPB-Sulfur, ULTRATM-1, SP-2100, BP-1, DC-200, PE-1 and ZB-1 columns.
