MXT™-UnionConnectorKits forFusedSilicaColumns
• Low-dead-volume, leak-tight connection.
• Reusable.
• Siltek® treatment ensuresmaximum inertness.
• Ideal for connecting a guard columnor transfer line to an
analytical column.
• Use tooven temperatures of 360°C.
• Available inunion and“Y”configurations.
• Can alsobeused for fused silica tometal connections.
TheseMXT™ connectors can be used with fused silica tubing,
because of a Valcon polyimide

-inch one-piece fused silica
adaptor. This unique graphite-reinforced composite allows a
capillary column to slide into the adaptor andbe locked inplace
simplyby loosening and tightening the fitting.
Valco™Connectors—One-PieceValconPolyimide
AdaptorFerrule forFusedSilica
Fused silica adaptor ferrules are Valcon polyimide, a unique
graphite-reinforced composite, specially prepared to maximize
mechanical stability at temperatures to 350°C. The determining
factor for selecting adaptor ferrule size is the fused silica
tubingOD.

Low-Dead-VolumeConnectorKits forMetal
Columns
These low-dead-volume connectors are Siltek® treated tomake
them inert to active compounds, just like ourMXT® columns.
They can be used at temperatures up to 430°Cwithout degrad-
ing the deactivated layer. Purchase the appropriate ferrules for
connecting 0.28, 0.32or 0.53mm ID tubing.
MXT™Low-Dead-VolumeConnector
Kits forMetalColumns
• Connect a guard column/transfer line
to anMXT® stainless steel column.
• Low thermalmass tracks rapidoven
temperature programming.
• Stainless steel ferrules andnuts.
• Available in“Y”andunion
configurations.
• Siltek® treatment ensures ultimate
inertness.
