in recent years phthalates have been accused of showing negative impact on human health. breast cancer in females or mental and motor development in children can be caused by long term exposure on phthalates. so it is important to have a good tool to detect them rapidly even at very low concentrations. in many laboratories research groups have been studying phthalates using different methods. the most common technique that phthalate esters were investigated is gas chromatography coupled with mass spectrometry (gc-ms), [1][2]. recently midey et al. present some results where high-performance ion mobility spectrometry with direct electrospray ionization (esi-hpims) was used to detect some phthalates [3].
近年来，邻苯二甲酸盐被指控对人类健康产生负面影响。长期接触邻苯二甲酸盐可导致女性乳腺癌或儿童智力和运动发育。因此，有一个好的工具来快速检测它们是很重要的，即使在非常低的浓度。在许多实验室，研究小组一直在用不同的方法研究邻苯二甲酸盐。研究邻苯二甲酸酯类化的方法是气相色谱-质谱联用(gc-ms)，[1][2]。近midey等人。本文介绍了用直接电喷雾电离高性能离子迁移率光谱法(esi-hpims)检测邻苯二甲酸盐的一些结果[3]。
in our laboratory five phthalates have been investigated using corona discharge ion mobility spectrometry (cd-ims) at atmospheric pressure. benzyl butyl phthalate, diphenyl isophthalate, diphenyl phthalate, ditridecyl phthalate and dimethyl isophthalate have been measured and limits of detection (lod’s) were determined. chemicals which we have studied are characterized by very low vapour pressures, for example vapour pressure of benzyl butyl phthalate is 2·10-4 pa [4], which means that these are non-volatile compounds and detection in gas phase can be difficult. for that particular phthalates lod obtained in our laboratory is tens of ppt.
在我们的实验室中，使用电晕放电离子迁移率光谱法(cd-ims)在大气压下对五种邻苯二甲酸盐进行了研究。测定了邻苯二甲酸苄丁酯、间苯二甲酸二苯酯、邻苯二甲酸二苯酯、邻苯二甲酸二异癸酯和间苯二甲酸二甲酯的检出限。我们所研究的化学物质具有很低的蒸气压，例如邻苯二甲酸苄丁酯的蒸气压为2·10-4pa[4]，这意味着它们是非挥发性化合物，在气相中很难检测。对于这种特殊的邻苯二甲酸盐，在我们实验室得到的lod是几十ppt。
