Elementar - Model soli TOC® cube -TOC analyzer for solids
The versatile instrument for temperature-dependent differentiation of carbon in solids. 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 offers 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 acidification methods, temperature programming can also be employed, which requires neither sample preparation nor the use of acids.- Unmatched analytical performance 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
- Simplified sample preparation 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
The soli TOC cube is optimized for TOC analysis. The following modes are available:
- Solid mode
The solid mode offers TOC, TOC400, TIC, TIC900, TC and ROC determination in solid samples with an autosampler for up to 89 sample positions. - TN mode
Simultaneous nitrogen determination with robust electrochemical detection.
Analysis method
True temperature ramping in an oxygenated atmosphere up to 900 °C for TOC400, ROC and TIC900 determination in solids compliant with DIN 19539. Alternative gas switching for combination of oxidizing and non-oxidizing carrier gases in one course to separate ROC and TIC900. Catalytic combustion for the determination of TOC in solids compliant with EN 15936. Option for simultaneous TN determination with ECD.
Large detection range
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).
Fully automated operation
Automated and unattended operation is possible by the integrated 89 autosampler and PC-control through Windows®*. Furthermore, optional 21 CFR Part 11 compliant software is available.
In accordance with official standards
The soli TOC cube operates in full compliance with all relevant national and international norms or standards such as DIN 19539, EN 15936, ISO 10694, and EN 13137.
