Mass Analyzers: Common Types01:19

Mass Analyzers: Common Types

The quadrupole mass analyzer consists of four cylindrical metal rods arranged in a diamond carrying a DC voltage and a radio-frequency AC voltage. The motion of ions through the quadrupole depends on the field strength, causing only ions of a certain m/z to resonate successfully and strike the detector at a given field strength. Though the transmission rate for these analyzers is high, the exact elemental composition of the sample is not determined because of low resolution; however, they are...

    Area of Science:

    • Optics
    • Photonics
    • Biophysics

    Background:

    • Fiber-optic traps are crucial for manipulating microscopic particles.
    • Understanding trapping forces is essential for optimizing optical tweezers applications.

    Purpose of the Study:

    • To calculate transverse and axial trapping forces in multiple-beam fiber-optic traps for dielectric microspheres.
    • To evaluate trap efficiencies based on various parameters and compare different fiber-optic trap configurations.

    Main Methods:

    • Ray optics regime calculations for trapping forces.
    • Analysis of microsphere properties (refractive index, radius) and beam parameters (waist separation, polarization, focusing).

    Main Results:

    • Trap efficiencies are dependent on microsphere refractive index, sphere radius, and beam separation.
    • Microlens focusing in two-beam traps can increase trapping volume but reduces transverse force stiffness.
    • Multiple-beam traps offer significantly firmer particle stabilization compared to two-beam traps due to strong gradient forces.

    Conclusions:

    • Multiple-beam fiber-optic traps are superior for stable particle manipulation.
    • Parameter optimization is key to maximizing trap efficiency and stability in fiber-optic tweezers.
