title: Batch introduction techniques.
abstract: Mass spectrometry (MS) is widely used as a rapid tool for peptide profiling and protein identification. However, the success of the method is compromised by dirty and contaminated samples. Moreover, analysis from a small sample volume with a relative high concentration is usually required. In this chapter, different microscale sample preparation methods are discussed for off-line, matrix-assisted laser desorption/ionization (MALDI) and nanoelectrospray ionization (nanoESI) MS analysis.
