As per ICH limit for Xylene is 2170ppm. Also it was specificied in ICH the Percentage purity of m,p and ortho xylene and Ethylbenzene also. My doubt is shall i fix the standard concentration for each of above as 2170 or otherwise shall i fix the standrad concentration with respect to purity of xylene which is mentioned in ICH.

Thanks
