One method of preparing samples for this technique uses a matrix of sinapinic acid which protonates the sample in response to a laser; that method is (*) MALDI (MAUL-dee).
One software package for this technique uses the XCORR (ECKS-core) score to determine the strength of a match; that software package is SEQUEST (SEE-quest). The Mattauch-Herzog (MA-tuck HURT-zog) geometry is used alongside a spark source in one type of this technique, which is an example of a sector instrument. One method of preparing samples for this technique uses a matrix of sinapinic acid which protonates the sample in response to a laser; that method is (*) MALDI (MAUL-dee). This technique yields a peak at M+1 for molecules containing carbon 13, and molecules containing bromine show a doublet in this technique. The base peak represents the most abundant species in this analytical technique, while the molecular ion is most likely the ion with the greatest m-z value. For 10 points, name this analytical technique in which a molecule is ionized and separated by its mass to charge ratio.
