High Resolution Microprinting With an Electrospray Printer

Electrospray ionization high-resolution ion mobility spectrometry-mass spectrometry.

A hybrid atmospheric pressure ion mobility spectrometer is described which exhibits resolving power approaching the diffusion limit for singly and multiply charged ions (over 200 for the most favorable case). Using an electrospray ionization source and a downstream quadrupole mass spectrometer with electron multiplier as detector, this ESI-IMS-MS instrument demonstrates the potential of IMS for...

Maintaining an Accurate Printer Characterization

In this study, the problem of updating a printer characterization in response to systematic changes in print-device characteristics is addressed with two distinct approaches: the creation of corrective models used in conjunction with an existing device model, and the re-evaluation of regression-model parameters using an augmented characterization data set. Several types of corrective models are...

treating refractory hypertension: renal denervation with high-resolution 3d-angiography

a 53-year-old male was referred to our department for refractory primary hypertension. despite high doses of 6 anti-hypertensive drugs, ambulatory monitoring of blood pressure (bp) revealed a mean bp of 160/90 mmhg. under local anaesthesia, renal denervation with radiofrequency was performed supported by high-resolution 3d angiography, which helped confirm the position of the applications in a ...

High resolution manometry – an introduction

High-resolution desorption electrospray ionization mass spectrometry for chemical characterization of organic aerosols.

Characterization of the chemical composition and chemical transformations of secondary organic aerosol (SOA) is both a major challenge and the area of greatest uncertainty in current aerosol research. This study presents the first application of desorption electrospray ionization combined with high-resolution mass spectrometry (DESI-MS) for detailed chemical characterization and studies of chem...
