Breathomics and Exhaled Breath VOC Profiling Service

Breathomics and Exhaled Breath VOC Profiling — Non-Invasive Metabolic Readout

Breathomics is the capture, identification, and quantification of volatile organic compounds (VOCs) in exhaled breath, analyzed by thermal desorption GC-MS to profile endogenous metabolism, microbiome-derived signals, and environmental exposures from a single non-invasive sample.

Every breath contains hundreds to thousands of VOCs — metabolic products from cells, tissues, and the microbiome, mixed with trace compounds from diet, smoking, and the environment. Because these molecules reach the breath via blood and alveolar exchange, the exhaled VOC profile is a real-time chemical readout of physiological state, obtained without needles, biopsies, or sample destruction.

Breathomics VOC analysis delivers:

• Non-invasive sampling: repeated sampling is feasible, enabling longitudinal monitoring in studies where blood or tissue collection is impractical
• Broad VOC coverage: hydrocarbons, ketones, aldehydes, alcohols, sulfides, and terpenes across endogenous and exogenous sources
• ppb-level sensitivity: thermal desorption pre-concentration detects trace VOCs that would be missed by direct injection
• Ambient air background control: inhalation air is profiled in parallel to separate endogenous signals from environmental background

What Breathomics Adds Over Blood or Urine Metabolomics

Blood and urine metabolomics require invasive collection and reflect metabolism over longer averaging windows. Breathomics complements them with a non-invasive, rapidly responsive VOC signature:

Breathomics vs. Blood and Urine Metabolomics

The two approaches are complementary. Where breathomics captures the volatile, rapidly exchanging fraction, our untargeted metabolomics service covers the deep non-volatile metabolome in blood, urine, and tissue — together they profile the same physiology from complementary chemical windows.

Exhaled Breath VOC Analysis Platform and Technical Parameters

Our breathomics workflows combine breath collection support with thermal desorption GC-MS analysis, configured for the VOC classes and sensitivity your study requires.

Volatile Organic Compound Coverage

Breathomics captures both endogenous metabolic products and exogenous compounds reflecting exposure:

For studies requiring deep coverage of non-volatile metabolites alongside VOC profiling, untargeted metabolomics provides complementary blood, urine, or tissue analysis from the same cohort.

Sample Requirements for Exhaled Breath VOC Analysis

Breathomics requires attention to collection standardization — the analytical quality depends on consistent sampling and background control:

Collection guidance: we provide a detailed breath sampling SOP for your study — including collection duration, storage conditions, and ambient air controls — so that samples arriving at our laboratory are reproducible across subjects and time points.

Why Choose Our Breathomics Service

Case Study: Non-Invasive Saliva Metabolomics of Tobacco Carcinogen Exposure

Metabolic reprogramming in saliva of mice treated with the environmental and tobacco carcinogen dibenzo[def, p]chrysene

Background

Oral squamous cell carcinoma (OSCC) develops in a tissue that is directly exposed to tobacco smoke constituents. Developing non-invasive metabolic readouts of exposure and early neoplastic change is a central goal in oral cancer research.

Challenge: Establish whether saliva — a non-invasively collected biofluid — reflects metabolic reprogramming induced by the environmental and tobacco carcinogen dibenzo[def, p]chrysene (DB[a,l]P).

---

Analytical Approach

In a mouse model faithfully recapitulating the human disease, comparative untargeted metabolomic profiling of saliva from DB[a,l]P-treated versus control mice was performed by UPLC-ESI-MS (Q Exactive Plus) analysis at Creative Proteomics — a non-invasive biofluid readout of carcinogen-induced metabolic change.

What This Means for Your Breathomics Study

• Non-invasive biofluids carry metabolic signal. This study shows saliva reflects carcinogen-induced metabolic reprogramming — the same principle underpins exhaled breath VOCs as a non-invasive readout.
• Exposure research needs trace-level sensitivity. Detecting carcinogen-related metabolic change in a dilute biofluid mirrors the ppb-level sensitivity required for breath VOC profiling.
• Complementary windows. Where saliva and blood capture non-volatile metabolome, breathomics captures the volatile fraction — together they profile exposure and physiology more completely.

Conclusion

This study demonstrates that non-invasive biofluid metabolomics can resolve metabolic responses to environmental carcinogen exposure. Our breathomics service extends this capability to exhaled breath VOCs — profiling volatile metabolism and exposure markers from a single non-invasive sample.
