Miniaturized Mass Spectrometer in Analysis of Greenhouse Gases: The Performance and Possibilities
It is no doubt that mass spectrometry (MS) is widely applied to several research fields. In recent years, design and development of novel miniaturized mass spectrometers have been at the forefront of research in MS. A lot of miniaturized mass spectrometers are reported and commercialized from a lot of institutes and industries. The instruments have widespread applications, for example, detectio...
متن کاملUV photodissociation of trapped ions following ion mobility separation in a Q-ToF mass spectrometer.
An ion mobility mass spectrometer has been modified to allow optical interrogation of ions with different mass-to-charge (m/z) ratios and/or mobilities (K). An ion gating and trapping procedure has been developed which allows us to store ions for several seconds enabling UV photodissociation (UVPD).
متن کاملMiniaturized time-scanning Fourier transform spectrometer based on silicon technology.
We present a miniaturized Fourier transform spectrometer (FTS) based on optical microelectromechanical system technology. The FTS is a Michelson interferometer with one scanning mirror. A new type of electrostatic comb drive actuator moves the mirror. We have measured a nonlinearity of the driving system of +/-0.5 mum for a displacement of 38.5 mum . A method is presented to correct the spectru...
متن کاملA MEMS-Controllable Fresnel Zone Plate for Miniaturized UV Spectrometer
This work presents the design and simulation of a MEMS-controllable linear motion Fresnel Zone Plate (FZP). The focal length of an FZP is a function of incident wavelength. This principle can be used for separating wavelengths, enabling a spectrometer application. The FZP of this work is designed on a linearly moving MEMS actuator, enabling wavelength focusing onto a fixed image plane. The FZP ...
متن کاملMineralogical determination in situ of a highly heterogeneous material using a miniaturized laser ablation mass spectrometer with high spatial resolution
Techniques enabling in situ elemental and mineralogical analysis on extraterrestrial planets are strongly required for upcoming missions and are being continuously developed. There is ample need for quantitative and high-sensitivity analysis of elemental as well as isotopic composition of heterogeneous materials. Here we present in situ spatial and depth elemental profiles of a heterogeneous ro...
