Welcome to the wonderful world of infallable science where no two labs can agree on anything and no two processes even come close. A PWT only reads ions for sure...maybe correctly and maybe not. Depends on what lab results you compare the readings to.
Do let us know what the titration lab comes up with that they're happy with. At least they admit there might be an error. That alone is a rarity.

Hi! I'm getting some confusing results here, from lab tests for ppm of concentrated CS. One lab is saying 50ppm in atomic absorption, but that they cannot measure for particulate silver with the technique. Another lab is saying 900ppm for another sample from the same batch, though telling me this is inaccurate and they'll repeat the procedure. But they're doing some titration process, which presumably does account for particulate silver. Is it true that atomic absorption will only measure ions? Does anybody know of some kind of simplified information that list all the various characterization techniques that apply? I'm thinking I'll try to get hold of the Hannah PWT device, a little more independent of the idiosyncrasies. Reid -- The silver-list is a moderated forum for discussion of colloidal silver.
