Question 6 (3 marks) (a) Describe how you could use both graphite furnace atomic absorption spectroscopy (GFAAS) or inductively coupled plasma emission spectroscopy (ICP-AES) to analyse a blood sample that is suspected to contained elevated levels of lead (b) If the same blood sample was also thought to contain high levels of arsenic in addition to lead, which technique would you use? Explain why
Briefly discuss why Internal Organizational Analysis is important. Then briefly discuss how the ultimate product of it is used with the ultimate product of External Analysis to give an inside/outside picture of the firm and its environment. (Hint: there is a third analysis technique you will need to mention and describe in your answer.)

2. An analyst is measuring cadmium in drinking water using Atomic Absorption Spectroscopy. The analyst prepares a set of calibration standards between 1 ppb and 50 ppb. The calibration curve is linear between these concentrations and the linear least squares equation is y=0.0127x + 0.0710. The analyst then runs a set of 4 drinking water samples. a) [What kind of standardization was used for this calibration curve: standard addition, internal standard, or external standard?] b) For sample 1, the analyst...
