Report Dr. Helal (Cara Evaluate Result)

1) Buat Calibration Curve (based on standard)

2) Determine concentration of each sample

• Based on the retention time for caffeine which is 7 min
  
• Use the area to determine the concentration of caffeine in each sample. (use the equation y=mx+c)
  

3) Determine the accuracy of the techniques

• Each concentration value is multiplied with dilution factor (the answer should be the same for each sample).
  
• Check for any deviation and discuss the reasons in discussion
  

4) Find the permissible concentration of caffeine in the drinks (search the internet)

• Compare the concentration of caffeine in sample in the guideline.
