Reliable headspace samplers provide good repeatability

Analyzing volatile components in a difficult matrix requires a reliable and robust solution. Shimadzu Scientific Instruments’ HS-20 Series of headspace samplers provides good repeatability through a technique that minimizes heat loss and thermal instability during the equilibration step. The oven can be heated to 300 °C, enabling accurate analysis of higher-boiling compounds. The series consists of a Loopmodel for the traditional static headspace methods, and a Trap model, which adds the dynamic headspace technique for applications requiring greater sensitivity. They hold up to 90 sample vials, and accommodate both 10-mL and 20-mL headspace vials within the same sequence. Shimadzu Scientific Instruments Inc.
