WebDec 31, 2024 · MALDI is attached to a time of flight (TOF) analyzer which measures time it takes for the molecules to travel a fixed distance. MALDI is a soft ionization technique in which a short laser pulse, instead of continuous laser, of nitrogen gas usually around 237 nm is used to ionize molecules. WebA nucleic acid amplification test (NAAT) is a type of molecular test that may use polymerase chain reaction (PCR) (or similar technologies such as NASBA, deep sequencing, etc.) to amplify a specific sequence of nucleic acid.
