TOC made easy Concept The concept of the high temperature TOC analyzer liquiTOC includes a separation of matrix compounds like salts or non combustible particles which is important to protect the catalyst from being poisoned or blocked. On the other hand a dynamic heating process allows high sample volumes up to 4ml thus giving a high sensitivity for low level TOC measurements. The basic concept of the instrument is shown in fig. 1. Summary The concept of matrix separation offers new applications for routine TOC analysis. The dynamic sample heating enables not only an effective matrix separation, it is as well possible to run high sample volumes up to 4 ml which was beyond the possibilities for high temperature TOC analyzer up to now.
