rapidCScube：新方法測定碳硫

　　德國Elementar公司推出的rapid CS cube，是最新型的快速碳硫分析儀，可分析煤、化學品、土壤/廢棄物等環境樣品中的碳和硫。相比于傳統的、把樣品放入坩堝入爐燃燒的碳硫分析儀，新型的rapid CS cube把樣品包裹入錫舟中。這種方式使樣品可以很容易地通過樣品進料器把樣品送入垂直燃燒爐(耐用的1000次進樣的球閥)。

　　在燃燒包裹入錫舟中的樣品時，溫度可以瞬時超過1800℃。這樣可以徹底地消解含碳和硫的樣品，確保碳和硫100%的回收率。

　　這種方式的優點還在于可以提供高的燃燒溫度，同時不再使用陶瓷反應管。rapid CS cube使用石英燃燒管，可獲得更好的分析結果。燃燒產生的CO2 和SO2 都可被非色散紅外測定(non dispersive IR，NDIR)，可以獲得寬的測量范圍，對< 1 mg/kg的碳和硫均可測定到100%。

　　這種可靠的分析方式也使分析不均勻樣品成為可能，可分析高達1 g的樣品。

　　儀器還可配置選件，進行液體和氣體樣品的分析，只需做最小的改動。

rapid CS cube - The New Way to Determine Carbon + Sulphur

The rapid CS cube is the latest generation of analyzers for the analysis of carbon and sulfur in coal, chemical products, environmental samples like soil and waste. Opposed to customary instruments where the sample is weighed-in into crucibles and fed into the furnace,
for rapid CS cube the samples are wrapped into tin boats. This has the advantage that the sample is simply thrown into the vertical combustion furnace through a sample feeder (the 1000 times proven ball valve).
 
During the combustion of the tin in the wrapping material temperatures of more than 1800°C are temporarily reached. This allows a complete digestion of all C and S containing compounds, thus guaranteeing a 100% recovery of these two elements.
 
This way also offers the advantage to realize high combustion temperature and to abandon the use of ceramic as the material for combustion tubes at the same time. rapid CS cube uses a combustion tube of quartz glass instead which leads to much better analysis results. Both CO2 and SO2 are determined by a non dispersive IR where the extremely large measuring range of the employed detectors allow the determination of C and S of <1mg/kg up to 100%.
 
 
A reliable analysis also of inhomogeneous samples is made possible with sample weights of up to 1 milligram.

As an option, liquid and gaseous samples may also be analyzed using minimal modifications.
