Answer / a.sudhakar
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.

in which situation require to use paddle and basket?
hii, i'm had a sample of 1L that gone through extraction & evaporation. i used 0.5ml of methanol for reconstitution before injecting the sample to HPLC. i made a calibration curve using a standard solution but now i'm confused about how to display the concentration i got from the sample. for ex. i got 0.2ug/ml how i'm gonna explane this is for the 1L ? please help .. i'll really appreciate it thanks
