The Apollo 9000 Total Organic Carbon (TOC) Analyzer uses combustion (680°C to 1000°C) with a patented reusable platinum catalyst for the lowest detection limits while maximizing TOC recovery. This TOC technique has the characteristics of being effective for difficult to oxidize compounds such as proteins, particulates and samples with high salt content. The analytical methodology implemented by the Apollo 9000 Total Organic Carbon (TOC) Analyzer optimizes rinsing on every injection to prevent carryover.
