Mass Spectrometry

This process is an instrumental method in which a sample is changed to fast moving positive ions by electron bombardment. The charged particles vary due to their different mass to charge ratio and are estimated with the help of this difference. It is also called mass spectroscopy.

5.4.5 Chemical microanalysis5.4.5.1 Exploitation of characteristic X-raysElectron probe microanalysis (EPMA) of bulk samples is now a routine technique for obtaining rapid, accurate analysis of alloys. A small electron probe (100 nm diameter) is used to generate X-rays from a defined area of a polished specimen and the intensity of the various characteristic X-rays measured usingeither wavelength-dispersive spectrometers (WDS) or energy-dispersive spectrometers (EDS). Typically the accuracy of the analysis is š0.1%. One of the limitations of EPMA of bulk samples is that the volume of the sample which contributes to the X-ray signal is relatively independent of the size of theelectron probe, because high-angle elastic scattering of electrons within the sample generates X-rays. The consequence of this is that the spatial resolution of EPMA is no better than ¾2 µm. In the last few years EDX detectors have been interfaced totransmission electron microscopes which are capable of operating…

Describe the origin of shot noise in a spectrophotometer. How does the relativeuncertainty vary with concentration if shot noise is the major noise source?
Anionic surfactants in wastewater are measured spectrophotometrically as methylene blue active substances (MBAS). A volume of a water sample is first reacted with methylene blue, a cationic dye, in a basic buffered aqueous solution. The resulting solution is agitated after the addition of chloroform. The organic layer is then extracted, and the absorbance is read at 655 nm. A standard calibration curve is produced by plotting absorbance vs. concentration for the concentration range between 0 ppm to 2.50 ppm. The line had the following equation: y = 0.286x + 0.009 a. The limit of surfactant content in Philippine class B water is 300 ppb. If a 5 mL aliquot of a 50 mL water sample had an absorbance of 0.084 after MBAS analysis, is the sampled water body suitable for bathing? Support your answer
