a) A mass spectrometer is designed to separate molecules out by charge/mass ratios. A test molecule weighing 3.32E-25 kg is first ionized to a +2 charge and sent through the mass spectrometer. If it traces out a semi-circle with radius of 10 cm in a magnetic field of 1.805 T, what is its velocity and what electric field is necessary to select this velocity? b) If a second molecule weighing 4.15E-25 kg is ionized to a -3 charge and sent...

Explain how a mass spectrometer is used to separate ions of different mass-to-charge (m/z) ratios by placing the statements in the order in which they occur. First step Gaseous ions are created in the ion source. The ions enter the vacuum chamber of the mass spectrometer A magnetic field is applied to the ions. The ions are deflected by the magnetic field. The velocity of the ions is increased as they pass through metal plates with a voltage applied to...

• The figure shows the essentials of a mass spectrometer, which can be used to measure the mass of an ion; an ion of mass m (to be measured) and charge q is produced in source S. The initially stationary ion is accelerated by the electric field due to a potential difference V. The ion leaves S and enters a separator chamber in which a uniform magnetic field is perpendicular to the path of the ion. A wide detector lines...

When using a spectrometer to measure the absorbance as a function of concentration, why do we have to plot our calibration curve at the maximum wavelength (lambda max)? I know it's to get the highest point of absorbance and therefore ensure high sensitivity, but how does it affect my answers on the calibration curve? what if I didn't use lambda max?

The picture above shows part of a mass spectrometer that can be used to measure molecular charge-to-mass ratios. A charged molecule (orange circle) is ionized and accelerated through an electric potential difference into a region with a uniform magnetic field. Here the magnetic field points out of the screen. The field makes the positively charged molecules undergo circular motion as shown. By adjusting the voltage difference between the plates, one can change the radius of curvature of the charged particles...

(8) In a mass spectrometer, an ion with a particular velocity is selected by using a magnetic field of 100.mt perpendicular to an electric field of 2.00 kV/m. After the ion leaves the velocity selector, the same magnetic field is used to deflect the ion in a circular path with a radius of 1.35cm. What is the ion's mass to charge ratio?
