EN 12619 Determination of Volatile Organic Compounds by Flame Ionization Detector
The EN 12619 standard is a widely recognized European standard for the determination of volatile organic compounds (VOCs) using a flame ionization detector (FID). This method is particularly useful in sectors such as chemical manufacturing, environmental monitoring, and quality control where VOC emissions need to be accurately quantified. The FID works by detecting the presence of organic compounds through their ionization when they pass through an electrically heated hydrogen火焰检测器（FID）。这种方法特别适用于化工制造、环境监测和质量控制等领域的挥发性有机化合物（VOCs）排放的准确定量。FID的工作原理是通过检测当有机物经过电加热氢气时发生的离子化来识别它们的存在。
在使用EN 12619标准进行测试时，样品通常需要先经过适当的预处理以确保其适合火焰离子化检测。这可能包括溶剂萃取、固相微萃取或顶空采样等技术。然后将处理后的样品注入气相色谱仪（GC），并通过火焰离子化检测器检测其中的挥发性有机化合物。
该方法的关键在于选择合适的色谱条件，如柱温程序、载气流速和进样量等，以确保不同种类的VOCs能够有效地分离并被FID准确地检测到。此外，还需要注意仪器操作参数的一致性和稳定性，以获得可靠的结果。
根据EN 12619的规定，测试结果应报告为每个目标化合物的浓度或质量分数，并且可以与国际标准如ISO和ASTM中的相关指南进行比较。这对于确保实验室之间的可比性和一致性非常重要。
通过使用这种方法，我们可以获得有关环境空气中VOCs水平的重要信息，这对于制定有效的污染控制策略至关重要。此外，在工业过程中监测VOCs排放有助于提高能源效率并减少废物产生。
Scope and Methodology
The scope of the EN 12619 standard is to provide a method for determining volatile organic compounds (VOCs) in various matrices such as air, water, soil, and solid materials. This includes both known and unknown VOCs that may be present in these samples.
- Known VOCs: These are specific compounds whose identities are already known.
- Unknown VOCs: These are unidentified compounds that need to be detected and identified during the testing process.
The methodology involves several steps, including sample preparation, extraction, concentration, injection into a gas chromatograph equipped with a flame ionization detector (GC-FID), and data analysis. The sample preparation step is crucial as it ensures that only the target compounds are introduced into the GC system for analysis.
