Vacuum-assisted extraction

Overview

Vacuum-assisted headspace microextraction allows faster extraction, lower sampling temperatures, enhanced sensitivity and greener methods.

This technique is compatible with HeadSpace, SPME and SPME Arrow, offering:

• A typical halving of extraction times when sampling under vacuum, reducing total cycle time for high sample throughput in analytical laboratories
• Avoidance of elevated temperatures to achieve high sensitivity, minimizing sample degradation and energy consumption
• Detection of more semi-volatiles without affecting the extraction of volatiles
• Repeatability and sensitivity for semi-volatiles
