场所空气中一氧化碳测定TDX-01填充柱应用安捷伦7890
场所空气中一氧化碳测定TDX-01填充柱应用安捷伦7890 详细信息：
分析系统主要包括：
气相色谱仪：配备FID检测器。
色谱柱：通常为内径2-3mm，长度1-2米的不锈钢或玻璃填充柱，内填60-80目的TDX-01碳分子筛。新柱在使用前需在150℃柱温、180℃检测器温度下，通氢气老化10小时。
镍转化炉：温度需稳定控制在360±1℃。转化柱一般为内径4mm、长15cm的不锈钢管，内填30-40目的镍触媒。使用前也需在360℃通氢气活化10小时。当一氧化碳浓度小于180mg/m3时，转化率通常高于95%。
气体系统：包括高纯氢气（作为反应气和FID燃料气）、高纯空气（FID助燃气）以及载气（如高纯氮气或氩气）。需特别注意载气中的氧气含量需低于1 ppm，以防高温下氧气损坏色谱柱固定相。
采样装置：常用铝箔复合膜气袋（如400-600mL容积）采集空气样品。
进样系统：一般采用六通阀进样，常见进样体积为1mL。

Determination of Carbon Monoxide in Place Air TDX-01 Filling Column Application Agilent 7890
Determination of Carbon Monoxide in Place Air TDX-01 Filling Column Application Agilent 7890 Details:
The analysis system mainly includes:
Gas chromatograph: equipped with FID detector.
Chromatography column: typically a stainless steel or glass packed column with an inner diameter of 2-3mm and a length of 1-2 meters, filled with 60-80 mesh TDX-01 carbon molecular sieve. The new column needs to be aged with hydrogen gas for 10 hours at a column temperature of 150 ℃ and a detector temperature of 180 ℃ before use.
Nickel converter: The temperature needs to be stably controlled at 360 ± 1 ℃. The conversion column is generally a stainless steel tube with an inner diameter of 4mm and a length of 15cm, filled with 30-40 mesh nickel catalyst. Before use, it is also necessary to activate with hydrogen gas at 360 ℃ for 10 hours. When the concentration of carbon monoxide is less than 180mg/m 3, the conversion rate is usually higher than 95%.
Gas system: including high-purity hydrogen gas (as reaction gas and FID fuel gas), high-purity air (FID auxiliary gas), and carrier gas (such as high-purity nitrogen or argon). Special attention should be paid to ensuring that the oxygen content in the carrier gas is below 1 ppm to prevent oxygen damage to the chromatographic column stationary phase at high temperatures.
Sampling device: commonly used aluminum foil composite film airbags (such as 400-600mL volume) are used to collect air samples.
Injection system: Generally, a six way valve is used for injection, with a common injection volume of 1mL.
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has developed a TDX-01 packed column for the determination of carbon monoxide in the air of production sites using Agilent 7890 hydrogen flame detector, portable methane conversion furnace gas chromatography method, and area external standard method for quantification. The results are satisfactory.
