Flexible temperature-dependent differentiation of carbon in solids

Flexible temperature-dependent differentiation of carbon in solids The determination of total organic carbon (TOC) in solids has recently become ever more important. Not just for evaluating wastes, the measurement of TOC content is also an important aspect of assessing soils. The soli TOC ® cube offers the option of measuring not only total organic carbon (TOC) and total inorganic carbon (TIC), but also determining the residual oxidizable carbon (ROC). In addition to the TOC determination by direct and subtraction acidification methods, temperature programming according to EN 17505 can also be employed (TOC 400 ). This requires neither sample preparation nor the use of acids and therefore saves time supporting efficient and sustainable laboratory routines. that is offered by the most sensitive instrument in the market with a limit of detection (LOD) of 10 ppm or < 15 μg Autosampler for time saving operation with 89 positions for secure, unattended 24/7 operation with automated ash removal due to our advanced crucible technology reducing time-consuming homogenization steps Unsurpassed measurement flexibility thanks to different analytical possibilities and optional total nitrogen (TN) determination Determination of carbon in soil, sediment, sludge and solid waste This Application Note shows how the parameters total organic carbon, total inorganic carbon (TIC), and elemental carbon (ROC) can be reliably determined in soil samples, sediments, sludge, and solid waste by using our elemental analyzers dedicated to carbon analysis.

It offers an unmatched measurement range from 0.001 – 100 % carbon. For the determination of temperature-dependent carbon fractions, a precise, adjustable temperature with fast heating rates is required for reproducible measurements. This is achieved by the dynamic heater of the soli TOC cubes which controls the temperature directly at the crucible position. This eliminates all possible thermal interferences and guarantees stable combustion conditions. Additionally, the use of a post-combustion catalyst ensures that even high carbon-content samples are quantitatively oxidized and achieve equally high measurement quality. For a better separation of residual organic carbon (ROC) and total inorganic carbon (TIC), the soli TOC cube offers carrier gas switching as a standard feature. The soli TOC cube is designed to significantly simplify the daily routine operation. The autosampler with 89 positions is optimized for unattended 24/7 operation. No time-consuming sample preparation due to the advanced temperature ramping and crucible technique: Just prepare your samples and start the analysis before you finish your workday and evaluate your analysis results at the next morning. The automated ash removal and clearly arranged, easily accessible system components minimize maintenance efforts. The tool-free clamp connection system ensures a reliably leak tight instrument at any time. Thus, you can enjoy smooth analyses and confidence in your results. Thanks to our advanced crucible technology, larger samples up to 3 gram can be easily analyzed. Just weigh the solid samples in the reusable crucibles, no time-consuming homogenization needed. This makes the soli TOC cube the perfect instrument for the comfortable, precise analysis of inhomogeneous samples. Measurement of TOC according to EN 15936 is also remarkably simple. The sample is acidified directly in the ceramic crucible and after drying immediately measured with the instrument – simple, fast, and reliable. Unsurpassed measurement flexibility for your analytical needs The soli TOC cube offers different analytical possibilities and an optional total nitrogen (TN) determination. The analysis of carbon in liquids at a certain concentration level can also be performed with the soli TOC cube. It is capable of distinguishing between the different forms of carbon in solids by either temperature programming or a temperature program combined with gas switching. In a single program, the TOC 400 , ROC, and TIC 900 can all be determined. Alternatively, the classical method of TOC analysis after pre-acidification and drying is also possible. Therefore, EN 17505, DIN 19539 and EN 15936/ ISO 10694 compliant analyses can be performed within only one instrument. The soli TOC cube is optimized for TOC analysis. The following modes are available: The solid mode offers TOC, TOC 400 , TIC, TIC 900 , TC and ROC determination in solid samples with an autosampler for up to 89 sample positions. Simultaneous nitrogen determination with robust electrochemical detection. True temperature ramping in an oxygenated atmosphere up to 900 °C for TOC 400 , ROC and TIC 900 determination in solids compliant with EN 17505 and DIN 19539. Alternative gas switching for combination of oxidizing and non-oxidizing carrier gases in one course to separate ROC and TIC 900 . Catalytic combustion for the determination of TOC in solids compliant with EN 15936. Option for simultaneous TN determination with ECD. From a few ppm up to 100% or 50 mg carbon and 20 mg (0–15%) nitrogen absolute (for the entire temperature ramp). Easy sample preparation and handling Without any special sample preparation, all kinds of solid samples are weighed into steel or ceramic sample crucibles (sample mass up to 3 g). Automated
