    Applications

    • Air separation plants
    • Argon purification plants
    • Cryogenic truck loading stations
    • Specialty gas laboratories
    • Process control
    • Steel industries
    • Chemical plants
    • Gas management system

    The K2001 analyzer is based on a spectroscopic emission cell, which is not a new technique in itself. It is in fact, the frequency, intensity, regulation as well as the coupling technique and focusing (stabilizing) electrodes used to keep the plasma stable that are the main characteristics that make it so sensitive, stable, and reliable.

    The cell volume is less than 1 c.c. The power coupling to the cell and the stabilizing electrodes help maintain plasma position and minimize turbulence caused by gas velocity. All this ensures a better penetration of the analyte (N2) into the plasma zone. The reaction involved into the cell may be described as follows:

    Ar* + N2 (X1Sg+)ot?Ar + N2 (C3llu)

    This is the action of metastable argon on nitrogen molecules. There is a strong emission of the second positive system of N2, from the vibrationnal level vl = 0. There is also a charge transfer ionisation/excitation involved caused by the transfer of charge between ions and atoms. Further information on this subject, however, will be found in future editions of the newsletter.

    Special attention is paid to the optical system. Each optical filter selected is tested with our spectrometer system before being included in a K2001. We select a filter coating to achieve optimum temperature stability and to avoid moisture-associated problems. This filter is coupled with a lens that focuses the beam of light so as to fix the center wavelength of the filter properly. The light is then directed to an enhanced photo diode. All these components are mounted in a cartridge to maintain optical path alignement.

    The signal conditionning differs in many respects from the competition. The K2001 amplifies the signal by direct-charge transfer. The new K2001 series comes standard with an analog-to-digital resolution of more than 1 part per million (20 bits) compared to the competition's 1 part per 4095 (12 bits). There is no bulky photomultiplier tube (PMT) with high voltage or a chopping wheel. Consequently, you do not have the problems associated with such systems.

    The entire system is controlled by a microprocessor. The quality of both parts and assembly makes the K2001 a choice instrument for the air separation industry. It is very popular, for example, in truck-loading stations.


    The following features set the K2001 apart from the competition:

    • User-friendly operator interface

    • Automatic or manual scale change
    • Low gas consumption (works with as little as 25 cc/min.)
    • Particle filter
