100% Dimethylpolysiloxane Industry standard general purpose column Non-polar Wide range of applications Superior performance of low molecular weight alcohols High temperature limit Bonded and cross-linked Solvent rinsable Wide range of column dimensions Equivalent to USP Phase G2 Applications...

GC capillary columns are typically wound on 7 inch cages that fit into standard-sized GCs like the 6890. The 6850 GC has a smaller oven which requires the use of columns wound on a smaller cage diameter. Nitroterephthalic acid modified polyethylene glycol High polarity Temperature range from 60 to...

The retention gap technique in combination with on-column injection allows concentration of a large sample volume in the capillary column. Choice of the retention gap depends on the solvent used: the flooded zone after injection should be between 20–30 cm/µL Me-Sil retention gap only for...

PERMABOND® Silane GC capillary columns for silane analyses Features Developed especially for the analysis of monomeric silanes and chlorosilanes (not for the separation of trimethylsilyl derivatives) Also suited for the separation of dimeric siloxanes and silazanes Columns with 0.32 mm ID: Max....
