[labnetwork] CDA cleanliness verification

[johnboyle]

Atlantic is the analytic company I refer clients to and Atlantic has been the independent lab certifying Air Products gas product purity for many years. I believe other other gas suppliers use them as well.John BoyleSent from my Verizon, Samsung Galaxy smartphone

Hello All,
Following up on the great advice provided on use of copper piping for CDA.  I am curious if anyone can provide a reference for a testing laboratory for measurement of CDA purity.  In particular we are looking to verify low levels of organics
 (10ug/m3) and inorganics NH4+ and SOx (5ug/m3).    
 
We would prefer a vendor in the mid-atlantic region but any references you would provide would be very helpful.

 
Thanks, and hope everyone has a nice holiday.
 
Kevin
