Without a clearly defined cause of multiple sclerosis, ways to prevent this disease have not yet been identified. Exercising regularly, getting sufficient sleep , or eating healthy meals will be of long-term benefit for many people, but have not been shown to be of help to prevent the development of multiple sclerosis. What research is being done on multiple sclerosis? Many areas related to the diagnosis and treatments of multiple sclerosis are being explored. These include more in-depth analysis of genetic factors, including factors which may help with the diagnosis and prediction of patient response to treatment options. Drugs which show promise in eliminating or preventing new multiple sclerosis lesions from forming are being evaluated; these new medications include drugs which would need to be injected, as well as drugs in a pill form. A good animal model of multiple sclerosis has not been yet developed; it is thought that a working animal model would help with the development of medications to treat multiple sclerosis. Stem cell therapy, which may help reboot a patient's immune system so that multiple sclerosis lesions no longer form, is being evaluated more closely.
There are several important analyser characteristics. The mass resolving power is the measure of the ability to distinguish two peaks of slightly different m/z . The mass accuracy is the ratio of the m/z measurement error to the true m/z. Mass accuracy is usually measured in ppm or milli mass units . The mass range is the range of m/z amenable to analysis by a given analyzer. The linear dynamic range is the range over which ion signal is linear with analyte concentration. Speed refers to the time frame of the experiment and ultimately is used to determine the number of spectra per unit time that can be generated.
