Abstract

To meet high expectations concerning precision and accuracy of reference materials, preparation of matrix-free reference materials using thermal decomposition-gas chromatography-mass spectrometry (TD-GC-MS) was proposed in this study. In the paper, the results obtained in preparation of the new reference materials for benzene and toluene are presented, based on the thermal decomposition technique of compounds chemically bound to the surface of optical fibre segments. The results obtained at various stages of the research procedure (homogeneity, stability) confirmed the possibility of using prepared laboratory samples of materials as reference materials for benzene and toluene. For the prepared batch of materials, reference values 1.26 ± 0.91 (ng/fibre) for benzene and 11.3 ± 7.4 (ng/fibre) for toluene were determined.

摘要

为满足对参考物质的精密度和准确性的高期望，本研究提出了使用热分解-气相色谱-质谱联用技术（TD-GC-MS）制备无基质参考物质的方法。本文基于化学键合在光纤段表面的化合物的热分解技术，展示了在制备苯和甲苯新参考物质方面所获得的结果。在研究过程的各个阶段（均匀性、稳定性）所获得的结果证实了将制备的实验室材料样品用作苯和甲苯参考物质的可能性。对于所制备的这批材料，测定出苯的参考值为1.26±0.91（纳克/光纤），甲苯的参考值为11.3±7.4（纳克/光纤）。
