Ever wonder what happens to samples before they’re analyzed?

At NOSAMS, organic carbon samples are carefully pre-treated using either acid-base-acid (ABA) methods or acid leaching to ensure accurate results. For select samples, we use our automated OCtoPuS — the Organic Carbon Pretreatment System.

Curious to see how it works? Watch OCtoPuS in action in this short video.
