The high cost for the pump ionization source mass

This preview shows page 1 - 2 out of 2 pages.

The high cost for the pump, ionization source, mass filter or separator, ion detector, and computer instrumentation and software has limited the wide application of this system as compared to the less expensive GC detectors (e.g., FID cost ~$3000; MS cost ~$40,000). However, the power of this technique lies in the production of mass spectra from each of the analytes detected instead of merely an electronic signal

that varies with the amount of analyte. These data can be used to determine the identity as well as the quantity of unknown chromatographic components with an asssuredness simple unavailable by other techniques. Components of the GC/MS Leaving the entire capillary GC system aside, the major components of the mass selective detector itself are: an ionization source , mass separator, and ion detector . There are two common mass analyzers or separators commercially available for GC/MS and they are the quadrapole and the ion trap . GC/MS Movie The movie available at this site is a short series of steps for the process of a single

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
