Question 1

what can we use the mass spectrometry for

Answer 1

1. determining the relative atomic mass of elements from isotopic abundances
2. using fragmentation patterns to determine the structures of organic compounds
3. finding the molecular formula by using HRMS

Question 2

what is a high resolution mass spectrometry

Answer 2

a type of mass spectrometry that can produce an Mr values to serval decimal places usually 4 or more

Question 3

why do we use HRMS

Answer 3

because from getting precise values of Mr we can find the compound, but not its structure

Question 4

where do we use HRMS

Answer 4

1. forensics
2. environmental analysis
