instrument. The source region and the ion guiding optics have higher pressure than the mass analyzer and the detector components. Vacuum requirements vary depending on the type of mass spectrometer and range from 1×10−3to 1×10−10torr. The ion source is used to convert solids, liquids,...
All mass spectrometers have an ion source, a mass analyzer and an ion detector. The nature of these components varies based on the purpose of the mass spectrometer, the type of data required, and the physical properties of ...
A.Almost everything! Salts, buffers, detergents and other small molecules can all interfere with liquid chromatography separation and mass spectrometer source ionization. Q.What is the best way to remove small contaminants? A.For protein samples,Pierce Polyacryla...

(b) Sector mass spectrometer. 1 = Ion source, 2 = magnetic field, 3 = collector slit, 4 = collector. Mass spectrometers with a single magnetic field sector are termed single focussing instruments. Good spectrometers of this type can have a resolution of up to 5000, where the resolution R...
PROBLEM TO BE SOLVED: To provide a tandem mass spectrometer which can perform tandem mass spectrometry on a trace quantity of a sample to be analyzed with a system selecting ions to be analyzed or ions not to be analyzed together with the ions to be analyzed before a first stage mass spect...
A mass spectrometer has an inductive coupled plasma-ion source and a mass filter located upstream of the ion source. The mass filter essentially allows free passage of atomic ions of a first mass-charge (m/z) ratio range, and greatly reduces the number of other ions whose mass-charge ratio...
