The soli TOC cube as a single elemental analyzer can therefore perform all of the measurement protocols outlined in DIN 19539 and DIN 15936. The determination of TOC in solids has recently become ever more important. Not just for evaluating wastes, TOC-content measurement is also an important aspect of assessing soils. The new soli TOC cube oers users the option of measuring not only total organic and total inorganic carbon, but also determining the total elemental carbon (ROC). In addition to the classical TOC determination by direct and subtraction acidication methods, temperature programming can also be employed, which requires neither sample preparation nor the use of acids. TOC 400 , ROC AND TIC 900 When determining the carbon content of solids, often it is not enough just to differentiate between TIC and TOC. When evaluating wastes, for example, elemental carbon (ROC) should be determined separately, since this form of carbon is not bioavailable. For this purpose, a temperature ramping program is used: TOC is determined at 400 °C, ROC between 400 °C and 600 °C, and TIC between 600 °C and 900 °C. The sample is heated at a rate of 70 °C per minute to the designated temperature, and then maintained for the given hold time. The CO 2 produced at the different temperatures represents the various carbon fractions. With the temperature programming of the soli TOC cube, one can determine the TOC 400, ROC, and TIC 900 simply and reliably, in compliance with the DIN 19539 standard. INNOVATIVE GAS SWITCHING The separation of ROC and TIC can be improved by the use of an inert carrier gas. After the 400 °C temperature step, the carrier gas is switched from oxygen to nitrogen and the sample is directly pyrolyzed at 900 °C. Under these conditions, the ROC remains in the sample container while the TIC is converted to CO 2. After the TIC is determined, the system is given oxygen again, whereby the ROC is oxidized. In most cases, this technique results in a better separation of TIC and ROC. Unmatched analytical performance In temperature programming, a precise, adjustable temperature is required for reproducible measurements. Thus in the soli TOC cube, the temperature is measured where it matters, directly at the crucible. This eliminates all possible thermal interferences. Additionally, the use of a post-combustion catalyst ensures that even samples with a high carbon content are quantitatively oxidized and achieve equally high measurement quality. With the soli TOC cube, larger samples on the order of grams can be reliably analyzed: just weigh the solid samples in the reusable crucibles, place them on the autosampler, and start the sequence. This makes the soli TOC cube the perfect instrument for the precise analysis of inhomogeneous samples. Measurement of TOC according to DIN 15936 is also remarkably simple. The sample is acidifled direct- ly in the ceramic crucible and after drying delivered immediately to the instrument – simple, fast, and reliable. The soli TOC cube is capable of distinguishing between the diflerent forms of carbon by either temperature programming or a combined temperature program with gas switching. In a single program, the TOC, ROC, and TIC can all be determined. Alternatively, the classical method of acidi4cation, drying, and TOC measurement at constant temperature is also possible. Furthermore, the nitrogen concentration of the sample can be analyzed at the same time as carbon by using an additional EC detector. Unsurpassed flexibility The software allows for implementing predeflned methods in addition to custom programming of the heating rate and hold times. Peak integration is executed automatically and can be manually checked. This ensures that even the most di4cult analyses can produce precise measurement of each individual component.
