Have you ever had to re-extract a sample because it had no surrogate?
QC standards are critical to the validation of final results.
Even
with a spike witness surrogates are sometimes missed.
With
tinted surrogate standards, you will immediately see which color
coded QC control standard is being added, and by viewing the tint
you can confidently verify that one or more standards have been
added.
The surrogate mix is 100% water-soluble and will not
extract out in your extraction solvent. (We do all custom mixes,
