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.

Hello Dear all; I have a technical question related to analytical Chemistry, I have a sample of (40% w/w) Ferric Chloride solution (for water treatment purposes which consist a little portions of Ferrous Chloride and Hydrochloric acid. I need to know the methods to determine the percentages of each Ferrous Chloride and Chloride acid. Also I want to make sure that this solution is truly (40% w/w). So ANY CLUE !!! Thanks in advance.
