Embodiment 1
[0060] In Example 1, MoF 6 Quantitative analysis of infrared spectroscopy as an example to illustrate, MoF 6 Produced by the reaction of fluorine gas and metal Mo foil.
[0061] Example 1
[0062] 1. Accurately weigh 1g of Mo foil and place it in the reactor part. After connecting the pipeline, vacuumize to confirm the airtightness of the overall system, including the gas preheating part, the reactor part, the gas sample pool of the infrared detection part, and the condensation collection part.
[0063] 2. The pipeline and cold trap of the reactor part and the condensate collection part are heated to 100 ° C, and 10 mL / min of fluorine and argon mixed gas (fluorine gas volume percentage 20%) and 10 mL / min of argon pretreatment (mentioned above The gas also needs to be preheated to 100°C), and flows through the infrared spectrum to quantitatively analyze the entire device and pipeline to remove trace moisture and avoid MoF 6 loss of response;
[0064] 3. After the pretreatm
