Animal Volatilomics

Non-invasive real-time animal VOCs analysis with SUPER SESI-HRMS.

 
  • Sampling is minimally invasive or non-invasive. Multiple sampling is possible

  • Pharmacokinetics Profiling in vivo and in real time

  • Real-time monitoring of processes.

  • Deeper understanding of animal's physiological responses and temporal variations.

  • Personalized medicine approaches via allowing for timely adjustments

  • Breath concentrations correlates with blood levels

 

Animal VOCs monitoring with SUPER SESI-HRMS technology, 5 reasons:

1- Real-time and continuous monitoring with 2 seconds resolution time

 

SESI-HRMS allows for the immediate availability of pharmacokinetic data based on mass spectrometric monitoring of exhalation. This real-time data provides superior time resolution of 2 seconds, this is because it's the time it takes for the gas to sweep through the entire system, this enables researchers to monitor drug levels in a single individual without delay.

“ The most significant advantage of the presented breath analysis method is that pharmacokinetic data based on mass spectrometric monitoring of exhalation is available instantaneously in real time”

2- Sensitivity below 1 pptv 

  • SUPER SESI-HRMS offers a limit of detecction below 1 pptv. By capturing a wide range of VOCs, SUPER SESI-HRMS allows for the identification and quantification of various compounds in  breath or bodily fluids. This comprehensive analysis facilitates a deeper understanding of metabolism, disease detection, and drug interventions. 

 

“The great sensitivity achieved by SESI-HRMS in the analysis of vapors, which can reach the low pptv range, allows the determination of not only volatile and semivolatile plasma components, but also low volatility compounds if present at sufficiently high concentrations. The limit of detection for this method, calculated as 3 times the signal to noise ratio, was found to be 0.6 pptv.”

3- High-resolution

SUPER SESI is coupled with the best mass spectrometers in the market, with high resolution mass spectrometry capability, SUPER SESI-HRMS provides accurate molecular identifications of VOCs . This enables to identify and quantify a wide range of metabolites present in animal´s breath or bodily fluids, facilitating comprehensive studies on metabolism, disease detection, and drug intervention.  This enables the detection of subtle changes in breath metabolites that may indicate specific health conditions.

4- Non-invasive monitoring

SUPER SESI-HRMS improves animal welfare since multiple compounds can easily be measured repeatedly in a single animal in-vivo. Also it results in more precise data with considerable time and cost savings

 

SESI-HRMS analysis of mouse breath is a promising strategy for minimally invasive, real-time pharmacokinetic monitoring using Ket, propofol, valproic acid, and their metabolites as examples.“

5- Application versatility, Customizable and easy implementation

  • The equipment required for SUPER SESI-HRMS is readily available and can be easily interfaced with commercial high-resolution mass spectrometers. The workflow is relatively easy to implement and allows for customization based on specific research requirements.

  • The data generated from SUPER SESI-HRMS is compatible with standard software for direct-injection mass spectrometry-based metabolomics, making it easy to analyze and interpret the results.

  • SUPER SESI-HRMS has diverse applications in animal research, including studying disease progression, evaluating treatment efficacy, and monitoring environmental exposures. It can also aid in the development of new diagnostic tools and therapies.
