haohan工业氨水测定专用HH-NH2-III填充柱应用赛默飞2m*1/8

工业氨水的气相色谱测定是一个可行的方案，但需要特别注意氨的特性（强极性、易挥发、易吸附、易溶于水）以及工业氨水可能含有的杂质。

核心挑战

1. 强极性 & 易吸附： 氨分子极性极强，容易在进样口、色谱柱（尤其是非极性/弱极性柱）和检测器管路中发生吸附，导致峰拖尾、灵敏度下降、重现性差。

2. 水含量高： 工业氨水通常含大量水（浓度在20%-30%左右）。水会严重干扰色谱分析，损坏色谱柱（特别是硅基固定相），在TCD上产生巨大响应，在FID上不响应但会导致基线不稳。

3. 易挥发： 氨沸点低（-33°C），极易挥发，样品处理和进样需要快速、密封性好。

  The gas chromatography determination of industrial ammonia water is a feasible solution, but special attention needs to be paid to the characteristics of ammonia (strong polarity, volatility, adsorption, solubility in water) and the impurities that industrial ammonia water may contain.
Core Challenge
Strong polarity&easy adsorption: Ammonia molecules have extremely strong polarity and are prone to adsorption in the injection port, chromatographic column (especially non-polar/weak polarity columns), and detector tubing, resulting in peak tailing, decreased sensitivity, and poor reproducibility.
High water content: Industrial ammonia water usually contains a large amount of water (concentration around 20% -30%). Water can seriously interfere with chromatographic analysis, damage chromatographic columns (especially silicon-based stationary phases), produce significant response on TCD, and not respond on FID but can lead to unstable baseline.
Volatile: Ammonia has a low boiling point (-33 ° C) and is highly volatile. Sample processing and injection require fast and well sealed conditions.
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has developed and produced the "Agilent Application of Industrial Ammonia Determination Special Filled Chromatography Column", which has high column efficiency and good separation. The results are satisfactory on Agilent, Shimadzu, Thermo Fisher, Varian, Brooke, and PE.
