Colour Coded Surrogates for BNAs!
Colour coded surrogates for semi-volatile extractions such as EPA
Methods 625 and 8270 can save costly mistakes in your laboratory.
These surrogates will Colour base-neutral solutions yellow and acid
solutions red. Now you can know positively whether or not the sample
has been pH adjusted for base-neutrals or acid extractions. Colour
coded surrogates also work with solid samples by tinting the sodium
sulphate used in the extraction. The Colour indicator is non-extractable
and will not affect results. Colour coded surrogates are methanol based
and supplied in 25mL volumes in screw top vials. Surrogates are always
supplied with Certificate of Analysis and MSDS.
Store in refrigerator.
