Mass spectrometers have low detection limits; however, the ionization of analytes may be suppressed by contaminants (including common buffer salts and detergents) present in samples.
Many commonly used reagents especially for biological samples have poor compatibility with mass spectrometric ionization techniques. Additionally, the mass spectrometer can be contaminated or clogged if crude samples containing non-volatile components are introduced into the instrument.
Consequently, sample preparation is a critical component of a mass spectrometric analysis and directly relates to the quality of data the instruments can realize.
Good sample preparation is essential for good data and preventing instrument damage.
