Markes Centri 180 Sample Enrichment Platform

The Markes Centri 180 automated sample enrichment platform for VOC analysis using GC/MS.

Markes Centri 180 is a versatile platform designed to maximize sensitivity for routine GC/MS analysis of VOCs / SVOCs in solids, liquid and gases using a range of sampling techniques.

By allowing busy laboratories to adapt to changes in demand for different applications, the Markes Centri 180 builds on the capabilities of the Markes Centri 90, and is available as an upgrade from Centri 90 in the field.

Efficiency is maintained by unattended sequencing of all application modes.

Built-in Multi-Gas capabilities in the Centri 180 allow a choice of carrier gases (helium, hydrogen, and nitrogen) to be used, enabling cost-savings and future-proofing your lab.

Features

Sample extraction from a variety of sample matrices using a range of dedicated sampling tools:
- Headspace (HS) and HS–trap.
- SPME and SPME–trap.
- SPME Arrow and SPME Arrow–trap.
Automated analysis of:
- Thermal desorption tubes.
- HiSorb™ high-capacity sorptive extraction probes (sampled offline).
Integrated inlet for injection/desorption of HS, SPME and SPME Arrow samples to the focusing trap. Centri 180 is designed for dual carrier gas compatibility.
Electrically-cooled, cryogen-free focusing trap enables analysis of compounds over a wide volatility range, including reactive and labile species:
- Simultaneous analysis of VVOCs, VOCs and SVOCs.
- Quantitative recovery of labile compounds.
- Quantitative recovery of high-boiling compounds up to n-C44.
Sample stacking and enrichment: Combine multiple vial extractions and/or tube desorptions onto the focusing trap prior to injection to the GC.
Inert, uniformly heated flow-path ensures complete recovery of analytes throughout the analytical system.
Use of automated tool-change robots allows optimum unattended sequencing of HS, HS–trap, SPME, SPME–trap, SPME Arrow, SPME Arrow–trap and any other robot capability configured.
Direct sampling from vials placed in vial tray with HS–trap and SPME Arrow–trap using Centri methods only
