Discrimination of prostate cancer cells and non-malignant cells using secondary ion mass spectrometry [PDF]

, 2008
This communication utilises Time-of-Flight Secondary Ion Mass Spectrometry (ToF-SIMS) combined with multivariate analysis to obtain spectra from the surfaces of three closely related cell lines allowing their discrimination based upon mass spectral ...

Novel analysis procedure for red ginseng polysaccharides by matrix-assisted laser desorption/ionization time-of-flight/time-of-flight mass spectrometry

Journal of Ginseng Research, 2021
Background: Red ginseng polysaccharides (RGPs) have been acknowledged for their outstanding immunomodulation and anti-tumor activities. However, their studies are still limited by the complexity of their structural features, the absence of purification ...

Multiplexed Ion Mobility Spectrometry-Orthogonal Time-of-Flight Mass Spectrometry [PDF]

Analytical Chemistry, 2007
Ion mobility spectrometry (IMS) coupled to orthogonal time-of-flight mass spectrometry (TOF) has shown significant promise for the characterization of complex biological mixtures. The enormous complexity of biological samples (e.g., from proteomics) and the need for both biological and technical analysis replicates imposes major challenges for ...

Formation of ultracold LiCs molecules [PDF]

, 2006
We present the first observation of ultracold LiCs molecules. The molecules are formed in a two-species magneto-optical trap and detected by two-photon ionization and time-of-flight mass spectrometry. The production rate coefficient is found to be in the

The role of a diffusion barrier in plasma display panel with the high gamma cathode layer [PDF]

, 2011
Plasma display panel (PDP) with MgO-SrO double cathode layer and SiO(2) diffusion barrier is proposed to make the SrO layer free of contaminations. Time of flight-secondary ion mass spectrometry (TOF-SIMS) analysis shows the diffusion of impurities, like

Time-of-flight mass spectrometry analysis of pulsed laser ablation of pyroxene

AIP Advances, 2019
Pulsed laser ablation experiments on pyroxene rock have been conducted. A 1064nm laser with a 0.7ns pulse width is used to generate ablation in vacuum. The resulting plasma plume is characterized with a time-of-flight mass spectrometer.
