A Dynamic Approach to High Sensitivity Headspace Analysis 

Extending Sensitivity for a deeper characterization of samples 

DANI Master DHS Dynamic Headspace Sampler provides you with the most sensitive and versatile system for headspace analysis.

In Dynamic Headspace Sampling technique, samples containing volatile organic compounds are placed in a closed vial and after thermostatting and initial molecules’ partition the headspace is purged by a constant flow-rate of inert gas for a fixed time. Volatiles are swept from the headspace and transferred to an adsorbent trap where they are cryofocused and concentrated. At the end of the concentration step, the trap is rapidly heated, the volatiles are desorbed in back-flush mode and sent to the GC column.

When compared to Static Headspace sampling, Master DHS presents two main advantages:

  1. the extraction step is no longer dependent on the thermodynamic equilibrium between the liquid/solid phase and its headspace. It means that extraction is less affected by the sample matrix. This benefit is particularly evident for compounds that show high solubility in the matrix and consequently low sensitivity when the Static Headspace approach is applied.
  2. Increased sensitivity for all analytes as a larger amount is extracted from the sample, concentrated and injected, compared to the Static Headspace approach where only a fixed volume of gas is sampled from the vial.

Master DHS can be used for both liquid and solid samples. Furthermore, it provides analysis of sample “as is“, without requiring the use of solvents for extraction and concentration purposes. This increases the sensitivity and eliminates any concern about solvent toxicity and solvent disposal problems when compared to a liquid extraction technique.
