Automated Liner EXchange (ALEX)

Automated Liner EXchange (ALEX)

Improved routine analysis of samples with high levels of involatile compounds, particulates and other solid matrix material

Matrix residue from samples can contaminate a GC inlet liner afterwithin a few runs, leading to peak broadening and loss of analytes through adsorption in the liner. Under such conditions, the analyst is forced to perform frequent liner replacement, an operation which normally requires manual intervention. Running large series of samples will represent a serious challenge.

Cooled Injection System (CIS)

Cooled Injection System (CIS)

GERSTEL Cooled Injection System – internationally the most frequently used PTV-type universal inlet, with patented septumless sampling head. Gas chromatographic analysis is now more versatile, reproducible and has lower detection limits than ever before, thanks to temperature programmed sample injection using GERSTEL Cooled Injection System.

easy Liner EXchange (eLEX)

easy Liner EXchange (eLEX)

GERSTEL eLEX: Fast and easy manual GC inlet liner exchange.

When analyzing samples with high levels of involatile or insoluble matrix residue, GC inlet liners can become contaminated a after just a few runs. Matrix build-up can lead to peak broadening and loss of analytes through adsorption in the liner. Under such conditions, in order to get correct analysis results, the analyst must regularly perform a liner exchange, an operation which normally requires several manual steps. Using eLEX this complex task becomes quite simple: An ALEX sampling head is mounted on top of the Cooled Injection System (CIS) inlet and whenever the liner has to be exchanged the pneumatic lock is released.
