摘要

近年来,微萃取技术(如固相微萃取、薄膜微萃取、管内萃取)给空气采样技术带来了革命性的变化。与传统的空气采样技术相比,这种先进的技术具有污染物提取率高、保留时间短、误差小的特点。记录了微萃取技术(MET)分离空气中挥发性有机成分、含氧碳颗粒和卤化碳颗粒的精度范围为90 ~ 95%。然而,当与气相色谱或气相色谱-质谱联用时,MET的效率增加了>3-5%。另一方面,传统的采样技术(如袋采样、抓取采样)显示的精度为~75- 80%,比MET低~20%。本研究对影响传统和MET性能的潜在因素进行了深入研究。例如,我们观察到,MET中使用的针涂层的质量显著影响污染物的捕获,并且由于涂层的损坏和腐蚀,至少有5%的总性能下降。此外,基于智能传感器的空气采样技术也正在研究中,因为这种技术是空气质量监测领域的最新发展。这种全自动的最先进的技术显示超过98%的准确度,具有显着高的灵敏度和污染物提取率。最后,本研究区分了先进采样技术和传统采样技术在提高准确性方面的潜在优势、劣势和挑战,引起了人们对提高本研究中调查的空气采样技术性能的迫切需要的关注。

Comparative investigations on microextraction and conventional air sampling techniques: challenges and future directions
Microextraction technique (e.g., solid phase microextraction, thin film microextraction, in-tube extraction) brings a revolutionary change in air sampling techniques over the recent few years. This advanced technique exhibits a high pollutant extraction rate, a low retention time, and a lower error margin compared to conventional air sampling techniques. The accuracy range of microextraction technique (MET) was recorded ~90-95% to isolate the volatile organic components, oxygenated and halogenated carbon particles from the air. However, the efficiency of MET increases additional >3-5% when employed by coupled with gas chromatography or gas chromatography-mass spectrometry. The conventional sampling techniques (e.g., bag sampling, grab sampling) on the other hand, displayed the accuracy of ~75- 80% which is ~20% lower than MET. The factors that potentially affect the performance of both conventional and MET were thoroughly investigated in this study. For instance, it was observed that the quality of needle coating used in MET significantly affects the pollutant trapping and at least ~5% of total performance cut off due to damaged and corroded coating. In addition, smart sensor-based air sampling techniques are also being investigated as this technique is a recent development in air quality monitoring. This fully automated state-of-the-art technology shows more than 98% accuracy with significantly high sensitivity and pollutant extraction rate. Finally, this investigation distinguishes the potential advantages, disadvantages, and challenges to increase accuracy between advanced and conventional sampling techniques, drawing attention to the urgent need to improve the performance of the air sampling techniques investigated in this study.
