恶臭硫化物的色谱测定是一个技术要求高、需要高度关注细节的分析领域。成功的关键在于:
选择合适的色谱柱和检测器: FPD/PFPD/SCD是气体样品的主流;极性柱+SCD/MSD常用于液体或衍生化样品。
使用高度惰性的采样和前处理系统: 吸附管采样-热脱附(气体)、吹扫捕集(水样)是最常用且灵敏的富集方法。所有接触面必须惰性化。
严格控制样品保存和操作条件: 避免吸附、氧化、光解、污染。
建立准确可靠的校准方法: 推荐使用外标法或内标法,标准曲线需覆盖预期浓度范围,并包含前处理步骤。
遵循相关标准方法并严格进行质量控制: 包括空白实验、平行样、加标回收率等。
通过精心设计和严格控制整个分析流程,气相色谱法能够准确、灵敏地测定环境介质和工业过程中的恶臭硫化物,为污染控制、工艺优化和质量监控提供关键数据。

The chromatographic determination of odorous sulfides is an analytical field that requires high technical requirements and attention to detail. The key to success lies in:
Choose appropriate chromatographic columns and detectors: FPD/PFPD/SCD are the mainstream for gas samples; Polar columns+SCD/MSD are commonly used for liquid or derivatized samples.
The use of highly inert sampling and pretreatment systems: adsorption tube sampling thermal desorption (gas), blowdown capture (water sample) are the most commonly used and sensitive enrichment methods. All contact surfaces must be inert.
Strictly control sample storage and operating conditions: avoid adsorption, oxidation, photolysis, and contamination.
Establish accurate and reliable calibration methods: It is recommended to use external or internal standard methods, and the standard curve should cover the expected concentration range and include pre-processing steps.
Follow relevant standard methods and strictly control quality, including blank experiments, parallel samples, spiked recovery rates, etc.
By carefully designing and strictly controlling the entire analysis process, gas chromatography can accurately and sensitively determine odorous sulfides in environmental media and industrial processes, providing key data for pollution control, process optimization, and quality monitoring.
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. used HH-S3 sulfur specific column flame photometric detector gas chromatography to determine six types of sulfides in ambient air, including hydrogen sulfide, methyl mercaptan, methyl sulfide, carbon disulfide, dimethyl disulfide, thiophene, etc. The influence of sampling container material was discussed. The method has good linearity, with detection limits of 1.1 μ g/m3 to 5.1 μ g/m3 for 6 sulfides, and RSD ≤ 8.5% for parallel determination of mixed standard gas,
