Electrospray Ionization – a soft ionization technique

Electrospray Ionization – a soft ionization technique Electrospray ionization (ESI) generates intact gas-phase ions from analytes in the solution for mass spectrometric investigations. It is…
Acoustic Levitation – a method for suspending matter in the air against gravity

Acoustic Levitation – a method for suspending matter in the air against gravity

Acoustic levitation uses acoustic radiation forces to counteract gravity and suspend objects in mid-air. It is a method for suspending matter in the air against…
Aerodynamic Levitation – the use of gas pressure to levitate materials

Aerodynamic Levitation – the use of gas pressure to levitate materials

In aerodynamic levitation, solids and liquids are floated in a vertical gas stream. Aerodynamic levitation is the use of gas pressure to levitate materials so…
