Hyun Jong You and his team at the National Fusion Research Institute (NFRI) in Korea have developed a Liquid-Helium-free, conductively-cooled Electron Cyclotron Resonance (ECR) ion source
in collaboration with the Korean firm JH Engineering.
The ion source
machine was unveiled by world-renowned physicist Professor Sir John Enderby.
A stat ion source
said: "Vanessa's appointment has gone down very badly.
The plasma chamber containing the RF-driven multi-cusp ion source
measures about 76 mm (3 inches) in diameter and 178 mm (7 inches) in length.
Among specific topics are the electrochemistry of the electrospray ion source
, a comparison of MALDI matrices, Fourier transform ion cyclotron resonance and magnetic sector analyzers for ESI and MALDI, ion activation methods for tandem mass spectrometry, and carbohydrate analysis.
It's modified ion source
and powerful differential turbo pumping system combine to increase the sensitivity by a factor of 2.
The new model, which features a new high-efficiency ion source
, simplifies pretreatment procedures while increasing sensitivity 2.
5 to 1,090 m/z) to allow analysis of higher mass compounds, as well as an extended ion source
temperature range (from 100[degrees] to 300[degrees]C) to increase flexibility and reduce maintenance, according to the company.
In an earlier study linked to an investigation of why negatively charged ions kill bacteria, Goheen found that discharging a negative ion source
into a flask containing a little water created ozone in the neighborhood of 1,500 parts per billion (ppb)--vastly higher than the U.
The cross-licenses are related to three US patents: "Mass spectrometer and method and improved ion transmission" assigned to MDS Health Group; and "Spectrometer provided with pulsed ion source
and transmission device to damp ion motion and method of use" assigned to the University of Manitoba (with which MDS Sciex works); as well as Millipore's (Waters' former parent company) patent for "Housing for converting an electrospray to an ion stream.
The second manuscript describes the results of a collaboration with an instrument manufacturer, to test new focusing plates and slits in the NIST ion source
and in an identical instrument at the Max-Planck-Institute for Chemistry in Mainz, Germany.
