I am given that, 3,6,9,12 and 15 micrograms per mL are my standard concentrations are my x values. how do are figure the y values which is absorbance. what do i need to do?Determine the structure for the molecule that most likely produced these spectrarnter the value from the y axis. determine both base peak and molecular ion peak
- Explain why electrospray ionization in mass spectrometry often results in detection of only the parent ion peak for a molecule, and why the detected ions are often 1 mass unit greater than 8. mass of the molecule.What a molecular ion peak has characteristics and how we can identify it? Explain.True or False 1. Photodiode arrays are devices within the instrument that help amplify the signal of a sample. 2. Atomic spectroscopy requires the atomization of a sample, which involves nebulization and eventually volatilization to form an elemental vapor. 3. Organic compounds are normally analyzed in atomic spectroscopy despite their small electronic transition range.
