Which of the following ionization technique uses a short laser pulse to achieve ionization?

Which of the following ionization technique uses a short laser pulse to achieve ionization? Correct Answer MALDI

MALDI is the ionization technique that uses a short laser pulse to achieve ionization. ESI, Chemical Ionization, and FAB do not use a short laser pulse to achieve ionization. The target plate containing the sample is placed in a vacuum chamber with high voltage and short laser pulses are applied.
