Consider the following statements as they apply to mass spectrometry. Decide if each is true or false. True False It is possible to get a mass spectrum of large analytes like polymers and biomolecules because of the development of ionization techniques such as MALDI and FAB. True False For a particular analyte, the mass spectrum obtained is highly dependent upon the ionization technique used. True False Though a gas chromatograph (GC) is a common way to introduce a sample into a mass spectrometer,...

What are the essential features of the following type of ionization mode used in mass spectrometry?...

What are the essential features of the following type of ionization mode used in mass spectrometry? Include whether it is a hard or soft process and what are the main benefits and/or limitations. a) Ramped or “Smart Fragmentation” (i mostly need this one) b) chemical ionization c) Atmospheric pressure chemical ionization

Mass spectrometry is a very accurate means of determining the mass and sequence of peptides, however some inconsistencies occur due to incomplete reactions and similar structures. a. Name two amino acids whose mass can’t be distinguished by mass spectrometry. b. If a bond between Ser and Val is not hydrolyzed, what amino acid could be mistakenly identified? c. If a bond between two Gly residues is not hydrolyzed, what amino acid could be mistakenly identified?

Why is tandem mass spectrometry more useful in analysis of peptides and proteins?
