An exploration of any one application of Spectroscopy (Absorption or Emission), Mass Spectrometry (MS) - (ANY kind of mass spec) Pick one location/project/bit of research where the data is used and explore. Discuss on what is measured (what instrument) and why and how. You don't have to fully teach the instrument but spend a paragraph giving the very basics of what is measured and how. And discuss the application you discovered - just find a place the measurement is used and explain what they do - what they measure and when it tells them.

As a forensic toxicologist, you have been given a task on determining amount of cadmium, mercury, chromium, copper and lead metal contents in medicinal herbs using flame atomic absorption spectroscopy (AAS). Hollow cathode lamp (HCL) was selected as radiation source for this analysis. The highest concentration came from lead element followed by chromium and copper, however cadmium and mercury were not detected in the sample. a) Based on your knowledge, conclude whether the above result is valid or not. b) If you are given an option of electrothermal or flame atomizer for above case study, determine which one is suitable and justify your answer.
2. The content of sodium in a cooking salt substitute for a low-sodium diet can be determined by atomic emission spectroscopy using the addition standard calibration method. 10.07 g of sample are weighted and solved in 10 mL 1M HCI and 100 ml of water. This solution is transferred to a 250.0 mL volumetric flask and water is added to the mark. Calibration standards are prepared adding to 5 different 50.0 ml volumetric flasks, 25.0 ml of the sample solution, and 0, 1, 3, 5, and 8 ml respectively of a standard sodium solution. The standard sodium solution has been prepared by dilution up to 100.0 mL of 20.0 ml of another solution that contains 0.2501 g Nacl in 1.0 L of water. Instrumental responses are the following ones: Volume of sodium 1.0 3.0 5.0 8.0 standard (mL) Response (a.u.) 1.79 2.63 3.54 4.81 6.18 Provide the concentration of sodium in the cooking substitute expressed in mg Kg!.

The levels of Vitamin B1 in a sample of milk was determined using the Standard Addition method and technique of fluorescence spectroscopy. 18.0 ml of the milk sample was diluted to 20.0 ml using distilled water and then the fluorescence was measured. The resulting signal was 210 units. A spike was made by taking 18.0 ml of the same milk sample, adding 1.0 ml of a 6.0 ppm Vitamin B1 standard solution, and then diluting to 20.0 ml using distilled water. The signal of the spiked milk was 540 units. Calculate the concentration of Vitamin B1 in the original milk sample (in ppm). Report to 3 decimal places.
