What is the difference b/w OVI Solvents and Residual
Solvents in case of Gas Chromatogaphy and What is its
Detection Limit?
Answer Posted / r.ramalingeswararao
In old days residual solvents are called ovi. these ovi solvent having very low ppm levels...but up dation on guidelines ovi is call and changed as residual solvents becz so many different solvents are used in manufacturing process with different levels ppm ranges.so there is no difference between ovi and residual solvents....only termnalise changed but processing method entire same procedure.

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?
