What does M/Z stand for?

Mass spectrometers identify the molecules present in a sample based on their mass-to-charge ratio (m/z).

About MALDI-TOF MS (Matrix-Assisted Laser Desorption Ionization-Time of Flight Mass Spectrometry) Mass Spectrometry (MS) is a technique used to screen simultaneously a multitude of molecules and determine the identity of microbes by exciting them with laser and analysing their protein pattern by analysing their individual mass-to-charge ratio.

Time-of-flight Mass Spectrometry Device The TOF-MS device enables a mass spectrometry in which an ion's mass-to-charge ratio is determined via a time measurement.

Whether or not the biomarker is present in this more select sample can then be determined using mass spectrometry - a technique where the molecules are charged and identified from their mass-to-charge ratio.

The spectra showed a mass-to-charge ratio of 919 for the molecular ion, while the fragment peaks were shown at mass-to-charge ratios of 757, 465 and 303.

They include ion-chromatogram extraction for mass-to-charge ratio (m/z) analysis of the expected metabolites, isotope cluster analysis if the metabolites are expected to display unique isotopic patterns and comparative analysis against control samples.

Electrospray: An ionization strategy used to create a gas phase; charged analytes that can be separated based on their mass-to-charge ratio (m/z) and detected by mass spectrometry.

Ionized proteins are accelerated in an electrical field and their mass-to-charge ratio measured.
