Breath Holder 

Offline breath analysis system

Breath holder is a complete solution for offline analysis of VOC samples, including collection, preservation, transport, and SESI-MS analysis.

Designed to facilitate Super SESI analysis with:

  • A distributed sampling network,

  • Minimum sample interaction, and

  • Controlled preservation conditions preventing condensation and diffusion losses.

The Breath Holder System comprises:

  • VOC Storage system

  • Interface to Super SESI, for a seamless sample introduction and analysis

  • Breath sampling interface, compatible with EXHALION (for breath analysis). Guides the exhalation maneuver and collects a pre-defined breath fraction based on exhaled CO2, flow, and volume thresholds.

Breath Holder Benefits

Offline Breath Analysis with minimized confounders:

- Standardized exhalation maneuver and sample collection of desired lung fraction, compatible with online analysis.

- Controlled sample storage from collection to analysis: Nalophan – Stainless Steel chemical barrier with active temperature control and logging.

- Offline analysis is ideal for distributed sampling and high throughput studies where statistical significance is key

- Sampling canisters are ideal to minimize sample–sampler interactions and artifacts

► Breath Holder facilitates distributed sampling.

► Breath Holder minimizes confounding factors.

► Breath Holder is ideal for large-scale studies with several sampling sites and a central SESI-HRMS lab.
