Embodiment Construction

[0034] In some embodiments, the present invention provides a composition of glass wool and an adsorbent material and an apparatus / device comprising the composition. In some embodiments, the compositions and devices / devices are useful for direct breath sampling. Further embodiments of the present invention relate to a kit comprising a breath sampling device / device, a method for its preparation and a method for breath sampling.

[0035] The present invention is based in part on the discovery that glass wool can be used not only as an end plug to hold the sorbent material, but also to form a matrix in which to bind the sorbent material. As exemplified herein, a matrix of glass wool combined with an absorbent material enables direct sampling of a subject's breath.

[0036] In some embodiments, the combination or matrix of sorbent material and glass wool has low resistance (e.g., compared to commonly used sampling devices / devices or sorbent tubes), allowing direct extraction of br...

In some embodiments, there is provided a glass-wool matrix and a sorbent material distributed throughout the glass-wool matrix.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of U.S. Provisional Patent Application No. 62 / 026,739, entitled "COMPOSITIONS FOR DIRECT BREATHSAMPLING," filed July 21, 2014, the contents of which are hereby incorporated by reference in their entirety. into this article. [0003] field of invention [0004] The invention relates to, inter alia, devices and methods for direct breath sampling. [0005] Background of the invention [0006] Breath analysis methods are based on the collection and analysis of breath samples from human and / or animal subjects. Currently, the methods used for breath analysis sampling can be divided into two main options: i) direct inhalation into sampling devices, and ii) indirect sampling using sampling bags or canisters. To avoid dilution or loss of sample, direct breath sampling is preferred multiple times. However, direct breath sampling is not always feasible due to the high cost of the analysis syst...
