SilFlow GC Splitters

Splitters and Deans Switches Configurations to Suit Your Application

Trajan understands today’s chromatographers need to move from tubing-based flow systems to planar microchannel systems to deliver flexible chromatography solutions. SilFlow is an innovation in design and fabrication resulting in a highly efficient and reliable microfluidic platform that improves your GC connectivity to enable maximum chromatography performance.

Configuration options for your chromatography solutions

The SilFlow microchannel device (MCD) is available in a number of configurations. Three (3) port GC splitters allowing flow splitting options with three different configurations. Four (4) port GC splitters offering similar configuration flexibility as the 3 port solution. Deans' switch MCD, perfect for multidimensional analyses.

Chemically Inert

Enabled by Trajan’s expertise in surface chemistry, SilFlow features chemically deactivated stainless steel channels avoiding active sites experienced with conventional connections. SilFlow can be incorporated into your system without impacting your chromatography.

Low dead volume connections

Graphite or Graphite/Vespel ferrules cannot be used with the SilFlow MCD as the dimensional stability is not adequate and there is a risk of contaminating the channels. SilTite FingerTite metal ferrules result in a reliable zero dead volume connection, giving you optimized peak shapes.

Superb operational stability

Pressure capability - The SilFlow system can be operated at pressures greater than 25,000 psi (170,000 kPa). Thermal lag - SilFlow tracks oven temperature up to 20°C/min. The design of SilFlow alleviates cold spots and sample condensation. Maximum temperature - No practical temperature limit. Limited only by the temperature rating of the GC column being used, ≤420°C.

Easy to install and leak free

SilFlow kits incorporate SilTite FingerTite fittings that are easy to set up and can be tightened using finger force to achieve a perfect, reliable seal, even for the most sensitive MS systems – no wrenches required!
