Functional specifications

 

Ionization

 

Soft Ionization: use of Chemical Ionization (CI) methods such as PTR (Proton Transfer Reaction) ionization. Chemical Ionization provides less fragmentation than Electron Impact, which allows a better identification of the compounds.

The most commun reactions used for VOCs detection are Proton Transfer Reaction from H3O+, charge transfer reaction from  O2+ , NO+.

Negative ions, for example O–, can also be used.

BTrap technology

AlyXan innovative technology for Volatil Organic Compounds (VOCs) real time analysis:

The BTrap analyzer technology couples direct high resolution mass spectrometry and selective chemical ionization techniques to provide the most precise analysis of VOCs in real-time.

 

Selective chemical ionizations:

Those soft ionization methods are based on an ion-molecule reaction:

It is highly advantageous as the precursor ions will react only on the desired compounds, not on the matrix.

 

Among them, PTR-MS (Proton Transfer Reaction – Mass Spectrometry) with the precursor ion H3O+ is the reference method. It reacts extremely well and quickly on hundreds of VOCs (aldehydes, alcohols, acids, amines, aromatics and son on) without fragmenting. Besides, it doesn’t react on the air/water matrix (O2, N2, H2O, Ar…).

 

Other kinds of chemical ionizations (charge transfer and negative ions for instance) can also be used when necessary. Besides, the BTrap acquisition software enables alternating sequentially the analysis methods for a more comprehensive VOCs measurement.

 

High resolution Mass Spectrometry:

 

AlyXan is the only company providing minimized FT-ICR (Fourier Transform Ion Cyclotron Resonance) mass spectrometers in the world. Based on a permanent magnet trap, the BTrap analyzer is both transportable and powerful enough to provide traces (ppb) to % levels analysis. Its really high resolution indeed enables isobaric separation and a wide detection of compounds. Mass spectra are then really easy to interpret.

 

The whole analytical process to generate a mass spectrum (reagent ion generation, analyte ionization, analyte detection/quantitation) takes place within the measuring cell (no need of ions guide/transfer) in a few steps:

 

1) Precursor ion production: Water vapor is injected at a few E-6 Torr, during tens of milliseconds, into the measuring cell (vacuum enclosure at E-8/E-9 Torr). An electron beam from the cell filament is used to generate H3O+ ions (PTR-MS), which will be trapped into the measuring cell by the magnetic field of the analyzer.

2) Analyte molecules ionization: Gas sample is injected at a few E-5 torr, during hundreds of milliseconds, into the measuring cell. Then, ion-molecule reaction occurs between the sample and the reagent ions to generate analyte ions, which are also trapped by the magnetic field of the analyzer.

3) Ions detection: Detection of a signal is made by measuring the ions rotation frequency around the magnetic field’s axis. This whole analytical process (from sample injection to signal detection) only lasts a second! Then, all ions are ejected from the measuring cell to start a new measurement.

 

 BTrap technology benefits:   

 

  • Comprehensive detection.
  • Real time analysis.
  • High mass resolution.
  • Instantaneous absolute quantitation (no calibration needed).
  • Easy setup on-site and/or on-line.

 

BTrap analyzer is laboratory grade as well as truly adapted to on-site and non-technical users needs.  Besides, it is definitely the best value for money, compared to competing technologies!

Software

Different access levels softwares come with the BTrap instrument.

 

BTrap monitor software

 

The BTrap monitor software is an easy to use tool dedicated to control and monitor the elements of the instrument: pressure gauge, primary and turbomolecular pumps, valves…

 

                                                                                               

BTrap FT-ICR software

 

BTrap FT-ICR software is a powerful tool used for acquisition as data processing. Sequences which alternate analytical methods and/or measurement channels can be created in the software. That makes the software very efficient for continuous on site analysis. This tool permits also to make automatic quantification and live monitoring of the data obtained during an analysis.

Some functions can be tailor-made since FT-ICR is entirely written and maintained by our software development team.
