Mass spectrometry-guided refinement of chemical energy buffers.
Biocatalytic reactions often require supplying chemical energy and phosphate groups in the form of adenosine triphosphate (ATP). Auxiliary enzymes can be used to convert a reaction by-product-adenosine diphosphate (ADP)-back to ATP. By employing real-time mass spectrometry (RTMS), one can gain an insight into inter-conversions of reactants in multi-enzyme reaction systems and optimize the react...
متن کاملLatent fingerprint chemical imaging by mass spectrometry.
Latent fingerprints (LFPs) potentially contain more forensic information than the simple identification of the subject; they may contain evidence of contacts with explosives or substances of abuse. Chemical information can also be useful in resolving overlapping LFPs from different individuals. We used desorption electrospray ionization mass spectrometry in an imaging mode to record compound-sp...
متن کاملSelective Reagents for Chemical Ionization Mass Spectrometry
Much of the power of chemical ionization mass spectrometry stems from the finding that the characteristics of the Cl mass spectrum produced is dependent on both the nature of the reagent gas and the type of ion-molecule reaction used to ionize the sample. Different structural information can be obtained with different reagent gases. As a consequence, it is possible to control the type and quant...
متن کاملnternal energy deposition with silicon nanoparticle - assisted laser esorption / ionization ( SPALDI ) mass spectrometry
The use of silicon nanoparticles for laser desorption/ionization (LDI) is a new appealing matrix-less approach for the selective and sensitive mass spectrometry of small molecules in MALDI instruments. Chemically modified silicon nanoparticles (30nm) were previously found to require very low laser fluence in order to induce efficient LDI, which raised the question of internal energy deposition ...
متن کاملPerchloroethylene Analysis by Chemical Oxidation and Determination of Intermediate Products by Gas Chromatography, Mass Spectrometry
Abstract Background and Objective: Perchloroethylene (PCE) is a chlorinated hydrocarbon used as a solvent in many industrial processes. In contaminated water and soil a great deal of PCE is found. This study aimed to determine the rate of decomposition of PCE occurred after advanced oxidation. Material and Methods: In this descriptive-analytic study conducted (2011) in public health faculty...
