MS: Spectrum Measured by a SELDI TOF Mass Spectrometer
Description
The spectrum was taken from a sample of sheep blood. The instrument
used was a so called SELDI TOF (Surface Enhanced
Laser Desorption Ionisation, Time Of Flight) Mass Spectrometer.
Usage
data(MS)
Arguments
Format
A data frame with 45213 observations on the following 2 variables.
mz
mass / charge
I
Intensity
Details
The measured masses lie between m/z=1000 and 200000. The intensities
are raw output. Neither smoothing nor background subtraction was
applied to the spectrum.
