Restek Rxi-624Sil MS GC Capillary Column, 30 m, 0.32 mm ID, 1.80 µm, 13870

Product information "Restek Rxi-624Sil MS GC Capillary Column, 30 m, 0.32 mm ID, 1.80 µm, 13870"

Of the four dimensions, the Rxi-624Sil MS 13870 has the largest inner diameter (0.32 mm) and the thickest film layer (1.80 µm), at 30 m length. Alkylfurans, nitrosamines, solvents and terpenes are assigned as analyte groups.

Phase

Rxi-624Sil MS is a crosslinked Crossbond phase of medium polarity on a fused silica tube. Column bleed is low, thermal stability high and the surface inert. The columns are manufactured for column-to-column reproducibility and are well suited to validated methods.

Comparable phases from other manufacturers include Agilent VF-624ms, Phenomenex ZB-624plus and Quadrex 007-502, 007-624 and 007-608. Comparable part numbers are Agilent CP9104 and Phenomenex 7HM-G040-31. The USP phase class G43 serves for matching methods that name a phase class.

Temperature

The range of use starts at -20 °C. Upwards, 300 °C isothermal and 320 °C in a temperature program are permitted, depending on whether the oven temperature stays constant or follows a program.

Selection within the family

Anyone looking for the narrower cross-section at 30 m length will find it in 13868 with 0.25 mm ID and 1.40 µm film, that is 0.07 mm less inner diameter and 0.40 µm less film thickness than here. The 60 m column 13869 has the same values at twice the length. At the narrow end is 13865 with 20 m, 0.18 mm ID and 1.00 µm. Retention times change when the dimension changes, so the method has to be revalidated afterwards.
