Nowadays, a wide variety of chemicals has emerged because of increasing industrial and human activities. Thus, environmental chemistry laboratories performing analytical measurements need rapid and sensitive methods more than ever to get reliable quantitative data. For this purpose, a purge and trap gas chromatography–mass spectrometry (GC‐MS) method was developed and validated for the rapid, simple, and sensitive determination of the presence of naphthalene and its derivatives in waters. The method validation was based on specificity, calibration curve linearity, limit of detection (LOD) and limit of quantification (LOQ), accuracy (recovery), precision, matrix effects (MEs), and measurement uncertainty. This method showed excellent linearity from 1.00 to 40.00 μg/L except naphthalene (0.50–40.00 μg/L) because the correlation coefficients were higher than 0.997 for all analytes. The LOQ values varied from 0.312 to 0.746 μg/L, and the LOD values changed from 0.094 to 0.224 μg/L with relative standard deviations (RSDs) for all compounds below 10% (3.12–7.46), respectively. Recoveries ranged from 81.9% to 95.6%, and repeatability and reproducibility (in terms of RSD for six measurements) were lower than 10% in all cases. F test was subjected on the related data at 95% confidence level, and no statistically significant difference was observed. There was no critical ME (recovery varied from 80% to 110% in all matrices). In measurement uncertainty, the expanded uncertainties of each analyte were changed in the range of 0.39–0.52 μg/L, and the calibration curve and repeatability had dominant effects on the combined uncertainty. The application to real samples was successfully assessed by the developed method. These results indicate that the developed method is suitable for the determination of naphthalene and its derivatives in waters.

吹扫捕集气相色谱-质谱法在水中萘及其衍生物的灵敏分析检测中的适用性

如今，由于工业和人类活动的增加，出现了各种各样的化学物质。因此，进行分析测量的环境化学实验室比以往任何时候都需要快速和灵敏的方法来获取可靠的定量数据。为此目的，开发了吹扫捕集气相色谱-质谱（GC-MS）方法，并对其进行了验证，以用于快速，简单而灵敏地测定水中萘及其衍生物的存在。方法的验证基于特异性，校准曲线线性，检测限（LOD）和定量限（LOQ），准确性（回收率），精度，基质效应（ME）和测量不确定度。除萘（0.50–40）外，该方法在1.00至40.00μg/ L范围内显示出极好的线性。00μg/ L），因为所有分析物的相关系数均高于0.997。对于所有低于10％（3.12-7.46）的化合物，LOQ值在0.312至0.746μg/ L之间变化，LOD值在0.094至0.224μg/ L之间变化，相对标准偏差（RSD）。回收率从81.9％到95.6％不等，在所有情况下，重复性和可重复性（以六次测量的RSD表示）均低于10％。F检验对相关数据的置信度为95％，未观察到统计学上的显着差异。没有关键的ME（所有基质的回收率从80％到110％不等）。在测量不确定度中，每种分析物的扩展不确定度在0.39–0.52μg/ L的范围内变化，并且校准曲线和重复性对组合不确定度具有主要影响。通过开发的方法成功评估了对实际样品的应用。这些结果表明，所开发的方法适用于测定水中的萘及其衍生物。
