HI,I CLEARED BOB CLERK EXAM. MY INTERVIEW WILL BE ON 9TH OCTOBER,2010.PLEASE SEND ME INTERVIEW QUESTIONS AND ANSWERS. THANK YOU.
I have compare C2H2-air and C2H2-N2O flame AAS on determination calcium. Both use same range of std to plot calibration curve. (2-6ppm) When i measure the sample with phosphate, KCl and LaCl, C2H2-N2O flame give false positive result, around 0.5ppm. When i measure the sample with phosphste, KCl and EDTA. C2H2-N2O flame also give 0.5ppm false positive. But both above mentioned sample would not give false positive when measured by C2H2-air flame. What is the reason?
