Hybrid Instruments for Mass Spectrometry/Mass Spectrometry

Instrumentation Science & Technology, 1986
ABSTRACT In order to refine further the technique of mass spectrometry/mass spectrometry efforts are being made to combine the desirable features of sector based tandem instruments with those of triple quadrupole mass spectrometers. This has resulted in the construction of tandem mass spectrometers which incorporate both sector type analyzers and ...

Study of an actinomycin complex by mass spectrometry-mass spectrometry

Talanta, 1988
The characterization of components within actinomycin complexes may often be complicated by the lack of material and standards of known actinomycins. Mass spectrometry-mass spectrometry can be employed both as a separatory device and as a means of structural analysis.

A double quadrupole for mass spectrometry/mass spectrometry

Analytica Chimica Acta, 1980
Abstract A double quadrupole mass spectrometer has been constructed to study unimolecular and collision-induced dissociation products from mass-selected ions. The two quadrupoles are closely coupled and the dissociation products sampled from a 2.5-mm interquadrupole region.

Collision region for mass spectrometry/mass spectrometry

Analytical Chemistry, 1982
Mass spectrometry/mass spectrometry is fast becoming a valuable analytical technique. An integtral part of this technique is the fragmentation of the parent ion. A large number of fragmentation pathways are supplied through the use of collision induced dissociations. Some typical designs of chambers for these collisions are presented. The efficiency of

Atomic mass spectrometry

Analytical Chemistry, 1988
This is the third fundamental review on the subject of atomic mass spectrometry. No longer just a mainstay technique of organic analysis, mass spectrometry is increasingly being rediscovered as the method of choice in many inorganic analysis situations.

Mass spectrometry of valepotriates

International Journal of Mass Spectrometry and Ion Physics, 1979
The mass spectrometry of eight valepotriates and their derivatives has been investigated. Mass spectral fragmentation schemes have been proposed as well as the use of this fragmentation for structural elucidation. Structures of two valepotriates, acevaltrate and homoacevaltrate, have been clarified.

Diabetes and mass spectrometry

Diabetes/Metabolism Research and Reviews, 2001
Mass spectrometry (MS) has been successfully employed to investigate non-enzymatic protein glycation, a process relevant in diabetic disease. The high sensitivity and specificity of this technique allowed the development of methods that can individuate and evaluate some glycation markers to be validly employed in monitoring diabetes.
