Interpretation Introduction

Interpretation:

Description of distance of flight mass spectrometer and the difference between flight mass spectrometer and TOF instrument.

Concept introduction:

Distance of flight mass spectrometer or DOFMS helps in separating the ions which are of different mass-to-charge (m/z) by the distance which is traveled in a given point of time after acceleration.

Quantitative Analysis by External Standard Method Calcium in a juice sample is determined by atomic absorption spectrophotometry. A stock solution of calcium is prepared by dissolving 1.834 g of CaCl, 2H20 in water and diluting to 1000.0 mL. A substock calcium solution was prepared by transferring 10.00 mL of the stock to a 100.00 mL volumetric flask and diluting to the mark. Three standard solutions of calcium were prepared by transferring 2.500 mL. 5.00 mL and 10.00 mL of substock to 50.00 mL volumetric flasks and diluting to the mark. The sample is prepared by transferring 1.000 mL of fruit juice from the original bottle to a 25.00 mL flask and diluting to the mark. Strontium chloride is added to all solutions before dilution to avoid phosphate interference. Instrumental response of the standards is measured against the blank, and the following readings are recorded: 9.10, 18.6 and 37.0. The sampie reading is 28.1. Using the multipoint method, find the concentration of calcium in…
If a TOF mass spectrometer needs to scan an m/z of 600, what is the speed of this ion if it is accelerated through 4000 volts?  How long will this ion (at the speed calculated) take to drift 2.00 m through the spectrometer?  How many mass spectra can be taken each second if a new cycle begins each time this ion reaches the detector?
Chemistry Common Isotopes and Mass spectrum of element Mo are given below Most common isotopes: Mo-98; Mo-96 Mo-95; Mo-92; Mo-97 ; Mo-100; Mo-94   Calculate the average atomic mass of Mo How the MS determined the relative intensity (Scale of 100) and Isotope abundance (%)? Why absolute intensity was not used? Can detector sensitivity, ICPMS temperature influence the relative intensity? Explain
