Bruce Marx...CsPro. Did the digest trip. Ugly lab work, and did not work, per AA comparison. .
Bruce was instructed by Hach techs to use reagents without digestion. I have confirmed this with independent labs while using a reasonably accurate spectrophotometer. You and I have compared results of the same sample in the past and been within a few tenths...at least some of the time. Are there somewhere examples of the same calibrated sample being analyzed by both techniques and AA? -----Original Message----- From: Marshall Dudley [mailto:[email protected]] Sent: Friday, December 09, 2005 10:49 AM To: [email protected] Subject: Re: CS>Hach reagents Robert Berger wrote: > Hi Jim, The Hack reagants only measure the ionic content of the > solution.

"Ole > Bob" That is why if you want a total silver content, you have to digest the silver first when using a spectrophotometer, then it is all ionic.
