Optimized tray design provides maximum capacity for 10 or 20 mL headspace vials
MPS roboticpro allows automated exchange of syringe modules

MPS robotic


As a new member of the MPS family, the MPS robotic is a highly efficient GC/MS autosampler with extended robotic functionality. The MPS robotic provides reliable processing of complex tasks. Syringe holders and syringes are integrated in special syringe modules, which can be exchanged automatically within a running sequence when using the MPS roboticpro for maximum flexibility.

Proven MAESTRO control

The MPS robotic is controlled by the proven GERSTEL MAESTRO software in a simple and efficient manner. MAESTRO provides full flexibility by allowing an ongoing analysis sequence to be modified to incorporate priority samples. The built-in, context sensitive help function enables simple sequence and method development and setup.

GERSTEL Universal Syringe Module USM

The GERSTEL USM is a universal syringe module for liquid syringes ranging from 1 to 1,000 μL total volume. Given the extended volume range, most application requirements can be met without changing syringe modules, saving both time and money – and reducing the risk of error. The USM is compatible with the GERSTEL Gripper enabling automated performance of multiple sample preparation techniques. As an example, GC liners can be replaced automatically at a user defined frequency, using Automated Liner Exchange (ALEX). A further example is the automated thermal desorption of adsorbent tubes, solid samples such as polymers, or GERSTEL Twisters in the Thermal Desorption Unit (TDU).

TDU iconThermal extraction and thermal desorption of liquids and solids
In combination with the GERSTEL Thermal Desorption Unit (TDU), the MPS robotic performs automated thermal desorption of adsorbent tubes as well as thermal extraction of liquid and solid samples in disposable μ-vials. The μ-vials and the involatile matrix residue are removed and discarded following the analysis, keeping the GC/MS system clean and stabile.
Twister iconEfficient trace analysis with the GERSTEL Twister®
In combination with the TDU, the MPS robotic performs fully automated thermal desorption of up to 360 Twisters for ultra-trace determination of organic compounds in aqueous and gaseous samples. While the Twister stirs the sample, analytes are efficiently extracted and concentrated in the Twister sorbent layer. Analytes are transferred to the GC/MS system using split- or splitless thermal desorption, or even multidesorption mode enabling ultra-low limits of detection.
ALEX iconAutomated Liner EXchance (ALEX)
In combination with the Automated Liner EXchange (ALEX) option, the MPS robotic can automatically replace GC inlet liners. In this way, ALEX provides cleaner chromatograms and correct analysis results even when analyzing matrix laden samples such as QuEChERS extracts.
