Description

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.

The GERSTEL Automated Liner EXchance ALEX technology automates the task of replacing liners in the GERSTEL Cooled Injection System CIS. The ALEX system enables fully automated GC analysis of samples with a high matrix load as well as “dirty” extracts, which can be directly injected into the CIS using the GERSTEL MultiPurpose Sampler MPS. Specially designed trays can hold up to 14 or up to 98 CIS 4 liners in individually sealed, contamination-free storage compartments.

In connection with the MPS, the ALEX system enables automated CIS 4 liner exchange at user defined intervals in a sequence.

The GERSTEL MAESTRO-Software provides integrated control of the MPS, ALEX system and CIS. In combination with the Agilent ChemStation, a single method and sequence table control the entire system including GC and MS.
