FocusLiner™

Achieve 0.2% RSDs on your GC analyses
FocusLiner inlet liners feature a unique design that prevents the wool plug from shifting during repeated injections or sudden inlet pressure changes. They provide RSD values consistently in the 0.2% range; up to 50-times lower than traditional inlet liners with wool plugs.

FocusLiners incorporate a unique design to prevent shifting of the quartz wool during repeated injections or sudden inlet pressure changes. Tapers inside the FocusLiner hold the glass wool plug in an optimum position.

This positioning results in wool plug penetration by the needle tip during an injection. The wool provides a large surface area for sample vaporization, and the wiping action removes residual liquid sample from the needle tip, thus preventing droplet formation. This improves reproducibility as much as 10 fold, reduces solvent tailing, and lowers mass discrimination during split injections without any cost disadvantage compared to alternative liners.

FocusLiners are available for all major G.C. instruments, a variety of injection techniques, and for 0.10 mm I.D. Fast Capillary columns. For technical assistance or help chosing an inlet liner, contact Supelco Technical Service at (800) 359-3041 or e-mail us at techservice@sial.com.
