TURBOMATRIX™ HEADSPACE SAMPLERS

Significance of the Topic

The analysis of volatile compounds by headspace sampling plays a critical role in quality control, environmental monitoring and pharmaceutical testing. Advanced trapping headspace technology enhances sensitivity to sub-ppb levels and improves repeatability, enabling laboratories to detect trace contaminants with confidence.

Objectives and Study Overview

This document presents the design features and performance advantages of a combined standard and trap headspace sampler. It highlights key innovations in pneumatic control, thermal management and software integration aimed at lowering detection limits and streamlining laboratory workflows.

Methodology and Instrumentation

The system incorporates several technical elements to maximize analytical performance:

• Pressure-balanced sample path to ensure inert conditions and superior repeatability.
• Programmable pneumatic control (PPC) for precise gas routing and ease of method development.
• Built-in analyte trapping to concentrate volatile components and reduce water matrix effects.
• Overlapped vial thermostatting to maintain sample temperature consistency and increase throughput.
• Multilingual touch-screen interface for intuitive operation.

Used Instrumentation

The headspace sampler interfaces seamlessly with virtually any gas chromatograph or GC/MS system. Configurations include:

• TurboMatrix HS 16
• TurboMatrix HS 40 and HS 40 Trap
• TurboMatrix HS 110 and HS 110 Trap
• TotalChrom CDS and remote control software
• Waters Empower 3 for full 21 CFR part 11 compliance

Main Results and Discussion

Built-in trapping capability provides up to 100-fold improvement in detection limits compared to conventional headspace methods, achieving sub-ppb sensitivity. Pressure-balanced technology delivers highly reproducible injections independent of split ratio. Overlapped vial thermostatting increases sample throughput by reducing cycle times and stabilizing thermal conditions. Software-controlled injection volumes and pneumatic sequences simplify method transfer and ensure consistent performance across laboratories.
