• Significantly reduces analysis timewithout sacrificing resolution.
• Higher column efficiencies speedup separations.
• Ideal forGC/MS.
• Excellent for comprehensiveGC (GCxGC) as seconddimension column.
Narrow bore (less than or equal to 0.15 mm ID) columns are attractive alternatives to conventional-diameter capillary columns
because they provide faster analysis times and higher resolving power. As column ID decreases, column efficiency (plates/meter)
greatly increases. Therefore, resolution can be achievedwith a shorter column, which decreases analysis time. In addition, narrow
bore columns aremore compatible withGC/MS since typical flow rates are 1.0mL/min. or less, eliminating the need to split the
column flow at theMS interface. Conventional methods are easily converted to narrow bore columns, but some researchmay be
necessarydue to lower column capacities andhigher backpressures.

Operatingconsiderations for0.10mm IDcolumns
The small degreeof extracare involved inusing0.10mm IDcolumnswill bemore than repaidby faster analysesandhigher columnefficiencies.
0.10mm IDcolumns requirehigheroperatingpressures (>40psig),whichcan result inmore ferrule leaks, septum leaks, and sample flashback
through leaking syringeplungers. Connectionsmustbemonitoredand leak-checkedmoreoften.Operatinga0.10mm IDcolumnbelowoptimum
pressurewill causepoor resolutionandotherpoorperformance. Samplecapacityalso is reduced, relative towider-borecolumns. Takecare tonot
