Dear Sir/Madam

I am a research scholar in Delhi College of Engineering in New Delhi, India. I am currently facing a minor problem in my research. I would be very delighted if you could kindly help.

The problem is that how do I find out the mass percentage of impurities i.e., iron and silicon in a sample of silicon, possibly avoiding the use any sophisticated methods to some degree of precision.

I will be looking forward to your help with eagerness.

with regards
Sadullah Ibrahimi
