TOC are the lowest among all the used methods.
In contrast at higher ROC contents, results for TOC are clearly different from the results of the other techniques. In summary, the comparability of the TOC results of the different approaches vastly depends on the carbon fractions that remain in the sample. It is important to consider this when choosing the correct technique to determine the TOC content.
Determination of TOC contents in six different samples according to three different methods.

Elementar offers the most dynamic variety of products to serve various customer demands based on their application tasks. With the vario MAX cube, soli TOC cube and the acquray series, larger samples, on the order of grams, can be consistently analyzed. This makes them ideal instruments for the accurate analysis of inhomogeneous samples.
The measurements of the TOC according to method 2 and method 3 are incredibly simple. For the analysis, the samples are weighed into crucibles and delivered directly to the instrument.
In case of method 1, the sample is acidified directly in the crucible and after drying delivered to the instrument. When using the rapid CS cube and the vario EL cube, the sample is weighed into silver foil cups, acidified and dried before the measurement. Both are restricted to method 1 but they are also able to determine extra elements. The general sample weight used for these instruments is mg.
To directly establish the TIC of solid samples, the soliTIC module has been created to provide accurate and precise results. It is an extra device that can be simply connected to all cube models that can measure carbon, for example vario MAX cube, vario EL cube and rapid CS cube.

The micro-distillation method, which is based on fundamental thermodynamic dependencies, consists in measuring vapor and liquid temperature, together with monitoring the pressure inside a special micro-distillation flask as the sample distils under atmospheric pressure.

Subsequent chapters discuss the analysis of various types of organics in a logical and systematic manner. It provides guidance on the applicability of techniques in certain environments, the advantages and disadvantages of using one method over another, likely interference, the sensitivity of particular techniques, and detection limits.
