Automated Tube Exchange (ATEX)

Direct Thermal Extraction in disposable micro-vial inserts.

The ATEX option works together with the TDU, and enables the introduction of liquid, viscous or solid samples directly into the GC system via thermal extraction. Extracted analytes are refocused and concentrated in a Cooled Injection System (CIS) inlet prior to introduction to the GC/MS system.

High sensitivity – low detection limits.

The efficient extraction and concentration ensures highest possible sensitivity and lowest detection limits. The analysis system is kept free of high boiling contaminants and matrix residue ensuring best possible stability and system uptime.

Up to 196 samples

Up to 196 samples can be processed automatically for determination of VOC / SVOC in heavy or involatile matrices, eg. PCB’s in sealants. Following the analysis, the sample cup with the remaining high-boiling or solid residue is automatically removed.
ATEX helps to ensure maximum uptime and best possible analysis results by keeping non-volatile or complex matrix material out of the GC/MS system. Standard addition and other liquid phase sample preparation steps can be performed automatically by the MultiPurpose Sampler MPS. The complete system is controlled directly from the GERSTEL MAESTRO Software.
