A simple method of extraction and determination of organosilicon oxide polymers (silicones) in 0.1-0.5 g of formalin fixed tissue by atomic absorption spectroscopy is described. Before the tissue is extracted with n-heptane, it is dried in a desiccator containing concentrated sulphuric acid. The graphite tubes in the HGA graphite furnace are tubes with L'vov platform. The evaporation of n-heptane and a part of the charing of the tissue extract in the tube are done in the presence of oxygen (air). The significance of the employment of L'vov platform and the presence of oxygen are discussed. The methods detection limit (2 X S.D.) is about 0.009 microgram silicon/ml tissue extract which corresponds to about 0.5 microgram polydimethylsiloxane/g tissue.
本文描述了一种通过原子吸收光谱法从0.1 - 0.5克福尔马林固定组织中提取和测定有机硅氧化物聚合物（硅酮）的简单方法。在用正庚烷提取组织之前，将其置于含有浓硫酸的干燥器中干燥。HGA石墨炉中的石墨管是带有L'vov平台的管子。正庚烷的蒸发以及管中组织提取物的部分炭化在有氧气（空气）存在的情况下进行。讨论了使用L'vov平台和氧气存在的意义。该方法的检测限（2×标准差）约为0.009微克硅/毫升组织提取物，这相当于约0.5微克聚二甲基硅氧烷/克组织。
