GRS-65HT GC Capillary Columns
The GRS-65HT phases represent a (65% phenyl) methylpolysiloxane phase composition. They are a companion phase to the GRS-17 (50% phenyl methylpolysiloxane), but the additional 15% phenyl substitution provides greater selectivity toward compounds exhibiting induced dipole effects. This enhanced selectivity is most evident in the analysis of triglycerides where the resolution is "fine tuned" over that of the 50% phenyl substitution.
The GRS-65HT is a bonded phase which possesses excellent thermal stability and hence can be used routinely for high temperature analyses.
Columns coated with the GRS-65HT phase type are ideal for the analysis of biofuel/biodiesel total glycerin and methyl esters under ASTM Method D6584-00.
