- What is the molecular mass observed for Man9(GlcNAc)2 if it has a mass spectrometry ionization that imparts a +3 charge state? .Arrange the following steps according to the order of process in Mass spectrometry Ion Separation Ionization Output/Data Result DetectionBriefly explain the principles of APCI mass spectrometry
- The LC-MS (mass spectrometry) is set to positive mode (can only see positively charged ions). What is the other routine mode which the instrument can be set in and when would this mode be used and why?The properties of a molecule that are most frequently calculated are geometry, energy (compared to that of other isomers), and spectra. Why is it more of a challenge to calculate “simple” properties like melting point and density? Hint: is there a difference between a molecule X and the substance X?Each peak in the spectrum below can be used to provide a measure of the mass of this protein, you can work out the charge associated with each peak, and measures can be averaged to find the overall mass. Use simultaneous equations to find the charge associated with each peak in the spectra below, which will allow you to calculate the average mass of each species. Include an estimate of the error associated with this measure. Dont use chatgpt
