FT-IR IS CALIBRATED BY USING POLYSTYRENE FILM
PUT THE POLYSTYRENE FILM INTO THE SAMPLE HOLDER
AND SCAN IT FIXED WAVE NUMBERS ARE OBTAINED THEY ARE
3060
2849
1942
1601
1583
1154
1028
ACCEPTANCE CRITERIA IS +/- 1 CM
RESOLUTION: THE DIFFERENCE BETWEEN THE ABSORBANCE AT THE
ABSORBATION MINIMUM AT ABOUT 2870 CM AND THE ABSORBATION
MAXIMUM AT ABOUT 2849.5 CM SHALL BE MORE THAN 0.33
THE DIFFERENCE BETWEEN THE ABSORBANCE AT THE
ABSORBATION MINIMUM AT ABOUT 1589 CM AND THE ABSORBATION
MAXIMUM AT ABOUT 1583 CM SHALL BE MORE THAN 0.08.

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?
