GC COLUMNS | METAL (MXT®) CAPILLARY COLUMNS
General Purpose Columns
MXT®-35 Columns (Siltek® treated stainless steel)
(midpolarity phase; Crossbond® 35% diphenyl/65% dimethyl polysiloxane)
• General purpose columns for organochlorine pesticides, PCB congeners (e.g.
Aroclor mixes), herbicides, pharmaceuticals, sterols, rosin acids, and phthalate esters.
• Temperature range: 0 °C to 340 °C.
• Equivalent to USP G42 phase.
*Maximum temperatures listed are for 15- and 30-meter lengths. Longer lengths may have a slightly reduced
maximum temperature.
MXT®-50 Columns (Siltek® treated stainless steel)
(midpolarity phase; Crossbond® 100% methylphenyl polysiloxane)
• General purpose columns for pesticides, herbicides, rosin acids, phthalate esters,
triglycerides, and sterols.
• Temperature range: 0 °C to 300 °C.
• Equivalent to USP G3 phase.
