A Discussion On M/Z Of Trypsin-Digested Protein
You perform mass spectrometry on trypsin-digested peptides of 1g protein. a) One of the detected peptide ions has a +1 charge and an m/z ratio of 1267.78. What is the mass of this peptide in daltons? b) One of the other peptides ions has a +2 charge and an m/z ratio of 943.62. What is the mass of this peptide in daltons.
How Mass Spectrometry Works
Mass Spectrometry explained. A guide through the molecular kinetics of mass spectrometry. Learn how this technique works, and how it is used to identify isotopes and compounds by producing a unique 'fingerprint' for the test sample. Please ensure you view this PowerPoint as a show to see the animations.
Find radius of detection for hypothetical mass spectrometer
Lorentz force of particleof known charge in known magnetic field is deduced and equated to centripetal force which rearranged yields the radius of detection/ The radii of detection for different masses and velocities is then dedcued and a grpah of the spread shown

For the spectrum attached in document, I need help with calculating a possible molecular formula for this compound. This compound contains C, H, and Br. Can you also show your work, I want to check my work. Thanks.
What is Mass Spectrometry?
Mass spectrometry (MS) makes use of the motion of ions in electric and magnetic fields in order to sort them according to their mass-to-charge ratios. Thus, MS is an analytic technique by which chemical substances are identified by the sorting of gaseous ions in electric and magnetic fields. The instruments used in these studies
Mass Spectrometer
A mass spectrometer is a device that uses a magnetic field to sort atoms by mass. In this device, atoms whose masses are to be determined are ionized by stripping off one electron. They are then sent through a velocity selector that selects ions only with specific speed V, and these ions are sent into a region of space filled
