2. In biological research, mass spectrometry is a commonly used instrument that offers numerous advantages. Mass spectrometry can be coupled with chromatographic instruments, is suitable for surface analysis, and capable of analyzing complex molecular structures, among other strengths. About mass spectrometry, please answer the following questions: (a.) We have emphasized multiple times about the five major components of the optical. spectroscopy instrument, and a mass spectrometer also consists of five main components. Please try to list these five MS components and compare them to the five main components of the optical spectroscopy instrument. Describe the main function for each of the five MS components. (b.) Following (a.), please try to describe the basic measurement process of the mass spectrometry. (c.) The mass to charge ratio for A+ion is 1.97107kgC1. Calculate the mass of A atom. (d.) In high resolution MS, please finish the calculation using chemical atomic mass with 4 digits after the decimal point: (d-1.) CH2N+ (d-2.) N2
