Electro move from Dase potential to Dase potential
Answers
Answer:
Electrons move from high potential to low potential.
Answer:
Desorption electrospray ionization (DESI) is an ambient ionization technique that can be coupled to mass spectrometry for chemical analysis of samples at atmospheric conditions. Coupled Ionization sources-MS systems are popular in chemical analysis because the individual capabilities of various sources combined with different MS systems allow for chemical determinations of samples. DESI employs a fast-moving charged solvent stream, at an angle relative to the sample surface, to extract analytes from the surfaces and propel the secondary ions toward the mass analyzer. This tandem technique can be used to analyze forensics analyses, pharmaceuticals, plant tissues, fruits, intact biological tissues, enzyme-substrate complexes, metabolites and polymers. Therefore, DESI-MS may be applied in a wide variety of sectors including food and drug administration, pharmaceuticals, environmental monitoring, and biotechnology.
