Features and Benefits

• A bottom taper focuses sample onto the head of the column and minimizes sample contact with metal parts of the inlet.
• A taper at the top aids in minimizing sample flashback.
• Remember – the addition of quartz wool to your inlet liner promotes mixing of analytes, aids the vaporization of liquid samples, works as a trap to collect nonvolatile residue in the sample (i.e. protects capillary column from ‘dirty’ samples).

Recommended Applications
Taper / Gooseneck liners are recommended for the following sample or injection modes:

• Trace level analysis
• Active Samples
• Split / Splitless injection types

Features and Benefits
The SGE FocusLiner™ uses a unique design to hold the quartz wool in the correct position.

• Two focus points in the liner ensures quartz wool remains in the optimum location.
• The wiping of the needle by the quartz wool prevents droplet formation ensuring excellent reproducibility.
• The presence of the quartz wool improves vaporization minimizing high molecular weight discrimination.

Recommended Applications
The FocusLiner is recommended for the following sample or injection modes:

• General purpose
• Concentrated samples
• Dirty samples
• Split/Splitless injection mode

Product Specifications
FocusLiner available for Agilent, PerkinElmer, Shimadzu, Thermo Scientific, and Bruker / Varian injectors.

Features and Benefits

• Bottom taper focuses sample onto the head of the column and minimizes contact with metal parts of the inlet.
• A taper at the top aids in minimizing sample flashback.
• Ensures quartz wool remains in the correct position in the liner.
• Excellent reproducibility results from the wiping of the sample from the syringe needle and the prevention of droplet formation.

Recommended Applications
The Taper FocusLiner™ is recommended for the following sample or injection modes:

• Trace level analysis
• Splitless
• Dirty sample
• Wide boiling point range

Product Specifications
Taper FocusLiner available for Agilent, PerkinElmer, Shimadzu, Thermo Scientific, and Varian / Bruker injectors.

Features and Benefits

• ConnecTite™ liners facilitate maximum transfer of sample to the GC column and inhibit sample degradation by reducing contact with hot metal components inside the inlet.
• A hole in the liner body maintains gas flows in systems equipped with electronic pressure control.
• ConnecTite liners with a hole near the bottom are ideal for analyses where early eluting compounds may be affected by a tailing solvent peak.
• ConnecTite liners with a hole at the top improve analyses of aqueous samples.
• ConnecTite liners with a hole at the top are also ideal for analyses where compounds of interest elute away from the solvent peak.

Recommended Applications
ConnecTite liners are recommended for the following sample or injection modes:

• Trace level analysis
• Direct injection
• Active compounds
• Aqueous samples

Product Specifications
ConnecTite available for Agilent, PerkinElmer, Shimadzu 2010, Thermo Scientific, and Bruker / Varian 1075 / 1077 injectors.

Features and Benefits

• Straight liners facilitate higher split flows.
• Narrow bore straight liners facilitate fast GC work.
• Small injection volumes of less than 0.5 µL are best used.
• Narrow bore straight liners improve focusing of gaseous samples (purge, trap and headspace).

Recommended Applications
Straight liners are recommended for the following sample or injection modes:

• General purpose
• Concentrated samples
• Dirty samples (only if quartz wool is present)
• Gaseous samples
• Purge and trap
• Headspace
• Split / splitless

Product Specifications
Straight liners available for Agilent, PerkinElmer, Shimadzu 2010, 17A, 2014 and 2025 injectors, Thermo Scientific, and Varian / Bruker 1177 & 1078 / 1079 injectors.

Features and Benefits

• Bottom taper minimizes contact with metal parts of the inlet and focuses sample onto the head of the column.
• Top taper aids in minimizing sample flashback.

Recommended Applications
Double Taper liners are recommended for the following sample or injection modes:

• Trace level analyses
• Splitless
• Low boiling point compounds
• Active compounds

Product Specifications
Double taper available for Agilent, Thermo Scientific, and Varian / Bruker 1177 & 1078 / 1079 injectors.

Features and Benefits

• PTV and LVI liners generally have sintered glass beads or powder to increase the surface area and trap nonvolatile residue.
• PTV liners use baffles or a wisp of quartz wool to aid in vaporization of samples and retain droplets during low temperature injections.
• Side hole needles are recommended for these techniques to ensure effective distribution of sample within the liner.

Recommended Applications
PTV / LVI liners are recommended for the following sample or injection modes:

• Trace level analyses
• PTV / LVI
• Large volume Injections

Product Specifications
PTV / LVI liners available for Agilent / Gerstel, PerkinElmer, Shimadzu 2010 injector, Thermo Scientific, and Varian / Bruker 1078 / 1079 injectors.
