In response to a mandate from the European Commission, the European Committee for Standardization (CEN) called on the technical committee CEN/TC 276 to develop a European standard (EN 17035) to define bio‐based surfactants and enable quantification of the bio‐based carbon content of surfactants based on radiocarbon analyses. This analytical approach was tested through directly contracted analyses and through a round robin procedure at commercial facilities in Europe. Initial results were unsatisfactory and further investigation identified issues surrounding the degree of homogenization in the samples. In general, the samples were only homogeneous at the gram level while the maximum quantity of material that could be introduced to the analytical process was at the milligram level. Having identified the root cause of the discrepancies between measured and expected results, new samples were sent to six European laboratories. The results were satisfactory indicating linearity and accuracy across the measurement range.

确定表面活性剂的生物基碳含量

为了响应欧洲委员会的授权，欧洲标准化委员会（CEN）呼吁技术委员会CEN / TC 276制定欧洲标准（EN 17035），以定义生物基表面活性剂并实现生物基表面活性剂的定量基于放射性碳分析的表面活性剂的碳含量。这种分析方法是通过直接签约分析和在欧洲的商业设施中采用循环法进行测试的。最初的结果不尽人意，进一步的研究发现了围绕样品均质化程度的问题。通常，样品在克水平上仅是均质的，而可引入分析过程的最大材料量在毫克水平。确定了测量结果与预期结果之间差异的根本原因后，将新样品发送到六个欧洲实验室。结果令人满意，表明整个测量范围内的线性和准确性。
