Teif Azmon Espadana

In 2014, Teif Azmon Espadana Company was established for designing and manufacturing of some laboratory instruments such as Ion Mobility Spectrometry (IMS) with variety of ionization sources, included corona discharge, electrospray and low temperature plasma. In addition to standalone IMS, we can also manufacture IMS coupled with gas chromatography and high performance liquid chromatography (GC-IMS, HPLC-IMS). The company managers, with almost two decades experience in the field of IMS, have published a number of patents and different ISI papers regarding the instrumentation and application of IMS.
About Company
  • teifazmon-42


    Ion mobility spectrometry (IMS) emerged under the name of “plasma chromatography” in the 1970s and has been used for the trace detection of organic compounds. Simplicity, speed, low cost, ease of maintenance, and low detection limits (~ ppb) are luring scientists to IMS. Today, IMS is an accepted analytical method for qualitative and quantitative determination of trace amount of compound such as explosives, drugs, and environmental contaminants.
    Ion mobility spectrometer model CD-1500 as a powerful analytical apparatus can be used for trace detection of various chemical compounds in both positive and negative modes, simultaneously. This instrument can be easily used as the detection system after various extraction techniques such as SPE, SMPE, and LPME, helping us to apply for different research in academic and industrial laboratories.

    Principle of Operation

    IMS instrumentation is comprised of four major sub-components: an ion source, an ion gate, a drift region and a detector. Samples in solid, liquid or gaseous phase can be evaporated using an injection port and transferred into the reaction region of the IMS cell by carrier gas. Using the ion source, reactant ions are produced in atmospheric pressure and the product ions of sample might be produced from proton transfer reactions between analyte molecules and reactant ions. These ions move toward the detector, characterized by their gas phase mobilities in a weak electric field.

    Ionization source

    In IMS (CD-1500), a novel design is used to establish the corona discharge without interference of negative ions (e.g. NOX-, O2-). This results in higher sensitivity, higher resolution, simplicity of spectrum interpretation, and analysis possibility of halogenated compounds, NOx, SOx, O2, CO, or CO2

    Injection port

    IMS, CD-1500, has an appropriate new injection port, resulting in possibility of direct injection of the known sample volume, without tedious sample preparation steps.


    The IMS (CD-1500) utilizes specially developed proprietary software. This software makes it easy to view ion mobility spectrum as well as quantitative results (height and area of the peak), when the instrument is in operating mode. The software also allows advanced operators to further review and analyze results in 3D and chromatogram format.
