Sample Preparation Techniques on the Centri 90
The Centri 90 is designed to optimize automated extraction workflows for liquid and solid samples contained in standard vials. The system flexibly integrates multiple techniques on a single platform:
- Headspace-trap (HS): Sampling from the vapor headspace above the sample within the vial.
- SPME-trap and SPME Arrow-trap: Fast, high-sensitivity extraction with a variety of fiber coatings, optimizing analyte selectivity.
- HiSorb™ (High-capacity sorptive extraction): Fully automates immersion or headspace sampling using HiSorb probes. A diverse range of sorbent phases enhances the extraction efficiency of trace-level compounds in complex sample matrices.
- Cryogen-free focusing trap: Integrates Multi-Step Enrichment (MSE) to increase sensitivity, maintain sharp chromatographic peaks, and reduce operational costs.
- Multi-Gas support: The system is certified for safe operation with hydrogen carrier gas, helping to optimize costs and increase analytical throughput.

Modular Design: Upgrade Path to Centri 180
The hardware of the Centri 90 is designed in a modular format, ready to meet future expansion needs. When a laboratory requires analysis of gaseous sample matrices, the system allows for a direct upgrade to the Centri 180, adding a Thermal Desorption (TD) module with an automated tube tray. This facilitates compliance with even the most demanding air and material analysis methods without needing to replace the entire instrument.
