When to avoid direct injection and prepare samples thoroughly
Mass spectrometers measure the mass-to-charge ratio (m/z) of one or more molecules in a sample, and create spectra that can be used to determine the mass and structure of these molecules. Each mass spectrometer consists of an ionization source, to convert molecules to gas-phase ions, a mass analyzer to sort and separate the ions, and a detection system. There are many different configurations of mass spectrometers available, and it is important to consider the sample types being analyzed, and the resolution and speed of analysis required.
