Hi and thanks to all...

finally with the help of information from boilerplate and other feedback's I'm able to write my code.

Finally, the code I'm using is:

RewriteCond %{QUERY_STRING} ^cid=9&gases=nitrogen$
RewriteRule ^purity\.php$ http://example.com/gases/nitrogen.php? [R=301,L]

but, im not able to go EXTENSIONLESS.

pls let me know how to do that.
