Re: Anyone in Ireland or UK using Diachem Xylene or Formaldehyde
as a general rule ther's no reason why you couldn't get material from
another supplier, providing the material meets any Specifications you might
give. Whatever you do it must be documented, and you should always insist on
an Certificate of analysis supplied with each batch delivered (Not to be
confused with a Certificate of assurance- which does not have any assay
Eg. your formaldehyde might come from ICI UK, which supply BDH/Merck etc.
but you must specify the correct grade or type eg.37/12 Formaldehyde (40%
with 12% Methanol- Formic Acid content should be less than 7%)
One the worlds biggest manufacturers of Xylene is Shell, again there are
different grades- specify one with low sulphur content and a Cof A.
