With the best UK pricing available, and delivery times between 3-4 working days, we believe our value added technical service is second to none.

The Importance of GC Inlet Liner Selection

Vital to your gas chromatography is the selection of a relevant inlet liner: optimising your pick can increase peak areas and reduce detection limits by up to 300%.

Key considerations include:

• Ensuring the complete vaporisation of samples prior to reaching the column
• Avoiding any reaction with the sample
• Identifying a liner with a volume larger than that of the vaporised sample
• Minimising discrimination (not enhancing it)
• Considering the addition of quartz wool to increase the surface area, thus and promoting mixing
• Positioning wool in the optimum position within the GC liner
• During analysis of polar solutes and for splitless injections, ensuring the liner is deactivated

Why SGE?

The Trajan SGE inlet liner range aims provide the quality, range and ease to meet your performance objectives and give you confidence in your analysis:

• Every type of liner is catered for every type of analysis
• Colour coded by geometry for ease of selection
• Every pack includes a certificate with quality assurance test results
• Lowest level of Endrin & DDT degradation compared to competitor results
• The liners of choice for sensitive MS analysis
• Unique proprietary ‘thin film’ process guarantees every liner is fully deactivated
• Reproducible performance with every liner
• Built-in o-rings
• Compatibile with the industry’s most popular instrument models

Deactivation – You can trust SGE

Every batch of Trajan SGE inlet liners is tested for activity using the EPA 8081B method, ensuring that each batch has less than 3% Endrin breakdown. This quality assurance is validated by including a batch certificate with each product.

Color	Injection Technique	Sample types	Liner Geometry	How the Geometry Works
Green	Split/splitless	Trace level analyses Active compounds	Taper/gooseneck	A bottom taper focuses sample onto the head of the column and minimizes sample contact with metal parts of the inlet Remember – the addition of quartz wool to your inlet liner promotes mixing of analytes, aids the vaporization of liquid samples and works as a trap to collect non-volatile residue in the sample (i.e. protects capillary column from ‘dirty’ samples).

				SHOP TAPERED FOCUSLINER INLET FILTERS
Orange	Direct	Trace level analyses Active compounds	ConnecTite	ConnecTite liners facilitate maximum transfer of sample to the GC column and inhibit sample degradation due to hot metal components inside the inlet Systems equipped with electronic pressure control require a hole in the liner body to maintain system gas flows ConnecTite liners that have a hole near the bottom are best suited to analyses where a tailing solvent peak could affect early eluting compounds. ConnecTite liners with a hole at the top of the liner will improve your analysis with aqueous injections or where compounds of interest elute away from the solvent peak

Grey	PTV / LVI	Trace level analyses Large volume injections	PTV/LVI	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.
