Answer / s.kumar
According to WHO,USP and ICH guidelines,inorganic metals present in the drugs should not be more than 10ppm.this inorganic metals are very dangerous to health.during ash test inorganic metals are converted to metal sulphates and are very stable at 600 degree celcious.below 600 degree celcious all the organic impurities will get evaporated.
Thanks,
