• Real-time analysis provides instant feedback on pollution events
  • Single, selective analysis of chemically diverse compounds
  • High sensitivity and wide linear range (pptv to ppmv)
  • 24/7 operation with minimal downtime (<1% downtime for validation)

Industry Challenges

  • Odor compounds are chemically very diverse, making analysis very difficult for conventional analytical techniques
  • Odors are dynamic, requiring fast response, whereas odor panels and/or lab-based analyses are expensive and based on time-averaged samples
  • An objective human response to odors is usually only achieved by extensive training, but trained panelists still get fatigued
  • Human odor thresholds are often too low for low-cost instruments to be able match, in addition to their issues with selectivity


  • Comprehensive analysis, including inorganics and chromatographically challenging compounds
  • Real-time and high-throughput analysis options
  • High sensitivity and wide linearity range for all odor compounds
  • Designed and engineered for demanding laboratory, R&D, and on-site applications
  • Mobile instrument solutions


The SIFT-MS technique is the premium tool for a wide range of odor applications due to a unique set of characteristics:

  • High-sensitivity detection of all odorous compounds (e.g. sulfur compounds, amines, aldehydes, and organic acids) in one simple, rapid analysis
  • Direct analysis eliminates compound losses caused by preconcentration and chromatographic separation
  • Wide dynamic range and high selectivity of eight rapidly switchable reagent ions allows detection of traces of odorous compounds in a matrix containing high levels of innocuous VOCs.

SIFT-MS provides a consistent, objective measure of odor. Industry applications include:

  • Odor source profiling
  • Landfill and biogas analysis
  • Fence-line monitoring.

SIFT-MS platform capable of high-throughput gas and headspace analysis for VOCs and inorganic gases.


Auto-validation inlet allows switching between sample, calibration standard, and background gas streams.


Multi-port inlet enables multiple sample streams to be analyzed (e.g. cyclically from multiple odor sources).


Software package for viewing and analyzing Selected Ion Flow Tube Mass Spectrometry (SIFT-MS) data from multiple instruments, customizing analyses, and interacting with the Voice200ultra.

Compound Library

Access detection and quantitation parameters for over 1000 compounds to leverage the diverse capability of the platform.
