Scintigraphy of incidentally discovered bilateral adrenal masses
(Springer-Verlag, 1995-04)
The purpose of this study was to determine the patterns of iodine-131 6β-iodomethylnorcholesterol (NP-59) imaging and the correlation with computed tomography (CT)-guided adrenal biopsy and follow-up in patients with ...
A high‐temperature pulsed solenoid valve for supersonic jet introduction up to 550 °C
(The American Institute of Physics, 1989-03)
A pulsed solenoid valve which can operate up to 550 °C has been designed for supersonic jet introduction. This valve uses a novel design where the nozzle head, which serves as the hot oven, and the solenoid operator are ...
An ion trap storage/time‐of‐flight mass spectrometer
(The American Institute of Physics, 1992-10)
An ion trap/time‐of‐flight (TOF) mass spectrometer combination has been developed in order to combine the storage capabilities of an ion trap with the speed and resolution of a time‐of‐flight device. The ion trap is an rf ...
The design and performance of an ion trap storage--reflectron time-of-flight mass spectrometer
(Elsevier, 1994-02-24)
The design and performance of an ion trap storage--reflectron time-of-flight mass spectrometer (IT--RETOF MS) combination have been explored for detection of ions generated from both internal and external ionization sources. ...
The design of an atmospheric pressure ionization/time‐of‐flight mass spectrometer using a beam deflection method
(The American Institute of Physics, 1992-01)
A novel time‐of‐flight (TOF) mass spectrometer configuration has been designed which can be interfaced to a continuous ion beam source produced by atmospheric pressure ionization. The TOF device uses a beam deflection ...
Selective resonance enhanced multiphoton ionization of aromatic polymers in supersonic beam mass spectrometry
(Elsevier, 1991-07-15)
Various polymers have been studied using a pulsed laser evaporation method for volatilizing these species and entraining them into a supersonic jet expansion followed by resonance enhanced multiphoton ionization (REMPI) ...
Resonance enhanced multiphoton ionization of nucleosides by using pulsed-laser desorption in supersonic beam mass spectrometry
(Elsevier, 1989-04-01)
Pulsed-laser desorption is used as a means of volatilizing nucleosides into the gas phase for entrainment into a supersonic jet expansion. These species are then studied in a time-of-flight mass spectrometer by resonance ...
A continuous flow probe method for on‐line introduction of liquid samples for detection by laser desorption with resonant two‐photon ionization in supersonic beam mass spectrometry
(The American Institute of Physics, 1991-04)
A continuous flow probe is used as a direct inlet source for injection of liquid samples into a time‐of‐flight (TOF) mass spectrometer. The direct liquid inlet is coupled to laser desorption as a means of rapidly vaporizing ...
Design for improved resolution in a time‐of‐flight mass spectrometer using a supersonic beam and laser ionization source
(The American Institute of Physics, 1985-03)
This article describes the design of a time‐of‐flight mass spectrometer (TOFMS) constructed for optimum use with resonance‐enhanced multiphoton ionization spectroscopy in supersonic beams. The use of the supersonic beam ...
Design of a pulsed valve for high‐pressure NH3 injection into supersonic beam/mass spectrometry
(The American Institute of Physics, 1988-11)
A novel design of a pulsed valve for high‐pressure injection of NH3 for supersonic jet expansions is presented. This valve can operate up to 200‐atm reservoir pressure at 180 °C with a pulse width down to 100 μs. This valve ...
