Rtx®-65 and MXT®-65 Columns

By Restek

Crossbond® 65% diphenyl/35% dimethyl polysiloxane

  • General purpose columns for phenols, fatty acids.
  • Temperature range: 50°C to 300°C.
  • Equivalent to USP G17 phase.

In diphenyl/dimethyl polysiloxane stationary phases, increased phenyl substitution improves separation of aromatic compounds, owing to increased phase-analyte interaction. The Rtx®-65(Fused silica)/MXT®-65(Silcosteel®) phase contains a very high phenyl content. A unique polarity makes these columns ideal for a variety of analyses, from phenols to FAMEs. As a confirmation column for EPA Method 604 phenols, an Rtx®-65/MXT®-65 column produces a different elution order, compared to the primary Rtx®-5 column. Rtx®-65/MXT®-65 columns elute FAMEs according to equivalent chain length, similar to bonded Carbowax® columns. However, the Rtx®-65/MXT®-65 phase does not suffer the thermal stability limitations of other polar stationary phases.

The MXT®-65 (Silcosteel®) offers rugged, flexible, inert, Silcosteel® treated stainless steel.
