Color-Coded Surrogates

Color Coded Surrogates for Semi-volatile Extractions

Color coded surrogates for semi-volatile extractions such as EPA Methods 625 and 8270 can save costly mistakes in your laboratory. These surrogates will color 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. Color coded surrogates also work with solid samples by tinting the sodium sulfate used in the extraction. The color indicator is non-extractable and will not affect results. Color coded surrogates are methanol based and supplied in 25mL volumes in screw top vials. Surrogates are always supplied with Certificate of Analysis and SDS. Store in refrigerator.
