It is well known that some problems with the determination of organic analytes at trace level can occur. This issue is connected with contamination during each stage of the analytical procedure from sampling to sample preparation up to chromatographic analysis, which often leads to false-positive or overestimated results. Another problem associated with determination of analytes occurs at trace- and ultra-trace level is a background problem which is mainly dictated by techniques, glassware and solvents. This review provides information on main complications connected with determination of trace organic constituents in complex matrix samples. Error sources in the field of determination of trace analytes are described in detail. In addition, the type of the background in each of the stapes of analytical procedure is summarized.

众所周知，痕量水平的有机分析物测定可能会出现一些问题。这个问题与从取样到样品制备再到色谱分析的分析过程的每个阶段的污染有关，这通常会导致假阳性或高估结果。与分析物测定有关的另一个问题是痕量和超痕量水平，这是一个背景问题，主要由技术，玻璃器皿和溶剂决定。这篇综述提供了与复杂基质样品中痕量有机成分的测定有关的主要并发症的信息。详细介绍了痕量分析物测定领域的误差源。此外，还总结了每种分析方法中每种背景提取物的背景类型。
