What is capillary Mede of CE MS equipment?

In the first CE-MS interface a stainless steel capillary sheath around the separation capillary terminus was used instead of terminus electrode in typical CE setup.

What is capillary electrophoresis time of flight mass spectrometry?

In this work, capillary electrophoresis time-of-flight mass spectrometry (CE-TOF-MS) is proposed to identify and quantify the main metabolites in three lines of genetically modified (GM) maize and their corresponding nontransgenic parental lines grown under identical conditions.

Which of the following is an interfacing device for CE MS?

The basis of the interfacing technology is the coaxial solvent sheath flow or triple tube CE/MS interface.

What is capillary zone electrophoresis?

Capillary zone electrophoresis (CZE) is a technique successfully used for the separation of proteins, peptides, and nucleic acids. Other applications where CZE may be useful include analysis of inorganic anions and cations, such as those typically separated by ion chromatography.

How does CE MS work?

A CE/MS system works by first separating the ionic components of a sample by applying voltage to the sample. The ions will move through the capillary at different rates due to charge and frictional forces. The separated sample is then sprayed into the mass spectrometer which produces a spectra.

How does ESI MS work?

ESI uses electrical energy to assist the transfer of ions from solution into the gaseous phase before they are subjected to mass spectrometric analysis. Ionic species in solution can thus be analysed by ESI-MS with increased sensitivity.

What is capillary electrophoresis and gel electrophoresis?

Capillary electrophoresis is a technique which separates biomolecules on a capillary tube using a liquid or gel polymer medium. Gel electrophoresis is a technique which separates biomolecules on a vertical or horizontal plane using a polymer gel medium.

How do you clean ICP-MS?

For normal cleaning: Soak in 5% nitric acid for ~10 mins. Do not sonicate! Soak in >5% nitric acid for ~30 mins.
