FocusLiner™
quartz wool remains fixed in ideal position by two tapered sections

Split

universal Liner

concentrated samples

dirty samples

the addition of quartz wool to the inlet liner promotes mixing of analytes, aids the vaporization of liquid samples, works as a trap to collect non-volatile residue in the sample (i.e. protects capillary column from 'dirty' samples).

the two tapered sections in the liner ensure that the quartz wool remains fixed in the ideal position

the tapered section at the top prevents the quartz wool to move towards the septum while the taper at the bottom prevents the quartz wool to be pushed down by the syringe needle

this insures an excellent reproducibility of your analysis

Wide boiling point range

advantages of FocusLiner™ see above

Bottom taper focuses sample onto the head of the column and minimizes contact with metal parts of the inlet

especially important in splitless injection as the sample remains longer in the liner

Splitless

trace level analysis

active compounds

Quartz wool provides additional surface area for complete volatilization of the sample to minimize sample discrimination.

Quartz wool wipes any sample from the syringe needle, thereby increasing reproducibility and preventing sample residue build-up at the septum

Quartz wool traps non-volatile components and septum particles from reaching the column

A bottom taper focuses sample onto the head of the column and minimizes sample contact with metal parts of the inlet

ConnectTite™ Liner

Splitless

trace level analysis

active compounds

ConnectTite™liners facilitate maximum transfer of sample to GC column and inhibit sample degradation due to hot metal components inside inlet

systems equipped with electronic pressure control require a hole in the liner body to maintain system gas flows

ConnectTite™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.

gaseous samples
(also Purge and Trap, Headspace)

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 with a narrow bore

Narrow bore straight liners improve focussing of gaseous samples (purge, trap and headspace)

Splitless LVI

trace level analysis

low boiling point compounds

active compounds

the 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

injector Liner

PTV LVI

trace level analysis

large volume injections

PTV and LVI liners generally have sintered glass beads or powder to increase the surface area and trap nonvolatile residue

PTV liners use baff es 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
