The term masking generally refers to: A) Masking generally refers to the transformation of an interfering species into a form that is not detected. B) Selecting samples from which the identity has been masked. This procedure prevents the analyst from prejudging the outcome of the analysis. C) Removing any material that may interfere with an analysis.

(iii) You wish to determine the fluorescence lifetime of your sample using Time Correlated Single Photon Counting, TCSPC. Draw a sketch showing the layout and principal components of a suitable setup and explain the basis of the technique.
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.
About Atomic spectroscopy a) Explain the fundamental difference between the two main types of atomic spectroscopy: atomic emission and atomic absorption. Also explain the main difference in instrumentation between these techniques. Draw a sketch as support. b) Explain the advantages of using emission measurements in an inductive coupled plasma (ICP) instead of flame emission measurements. Motivate! c) Measurement of mercury (for example in Värmland Lakes) can be performed with flameless atomic absorption spectroscopy. Measurement with this technique gives a detection limit of about 0.01 ppb to compare with the determination of mercury in a flame that has a significantly lower detection limit, about 200 ppb. Explain why the flameless technology is so much more sensitive for measuring mercury. Please answer very soon will give rating surely All questions answers needed
