what is stability study ? why it is needed and how itis done
Answer Posted / sarma dvv
Stability means how long the drug was stable with out
losing original character.
drug compound will decompose at different environmental
conditions such as temperature,humidity & light....
From stability we can know thefollowing things
1.Re-test period of the drug.
2.Packing conditions of the drug.
3.Storage conditions of the drug(Temp and humidity)
Typical stability storage conditions of the drug.
1)accelerated Studies 40°c & 75 Relative Humidity
2)Intermediate studies 30°c & 65 Relative Humidity
3) Real time studies 25°c & 60 Relative Humidity.

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?
