This invention is a continuous flow, self-cleaning, simple, and versatile open port sampling interface for liquid introduction atmospheric pressure ionization mass spectrometry or for fraction collection for subsequent chemical analysis.
The vortex capture probe provides for capture of material from a laser ablation plume into a continuous flow stream of solvent enabling the means for uninterrupted sampling, transport and ionization of collected material for coupling with mass spectral analysis, including spot
The invention relates to Scanning Probe Microscopy and more specifically to information-theory analysis of the cantilever output stream.
Permanent magnet used in high-gradient configuration has been proven to be able to collect nanometer sized particles with extreme high efficiency.
The invention relates to magnetic amplifiers and more specifically to an apparatus and method of filtering unwanted harmonics from such amplifiers.
Liquid extraction-based surface sampling mass spectrometry (MS) employing spatially resolved confined liquid/solid extraction of the analyte(s) of interest from a surface is becoming an established analysis methodology.
The invention relates to optical characterization of samples.
We have established an approach for electrochemical measurements in polar liquids, combining the force-sensitivity of SPM with the ability to probe the bias and time dependence of material-dependent electrochemical dynamics at the tip-sample junction and spatially across bound
The slide-in-plant chamber is a small device compatible for use with microscopes (brightfield, confocal) for visualizing events occurring around or inside the roots of plants in real time over short (hours) or long (days) timeframes without sacrificing the plant.
This invention relates to sensors and more specifically to sensors and methods for measuring greenhouse gas concentration.
