Answer Posted / i.kizar ahamed
Organic compounds whichever is having conjugation can be
detected by UV DETECTOR. (ELECTRONIC TRANSISTION SHOULD BE
POSSIBLE)
For inorganic compound RI detector is uesd .
OVI :Organic volatile impurities
Based on the toxicity solvents has classified as
class1,class2,class3.
Class 1 solvents are
Benzene 2 ppm
Carbon tetrachloride 4 ppm
1,2-Dichloroethane 5 ppm
1,1-Dichloroethene 8 ppm
1,1,1-Trichloroethane 1500 ppm
Organic volatile impurities:
Chloroform ,1,4 Dioxane,MDC ,Trichloromethane

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?
