对于低浓度气体或蒸汽化合物的FT-IR分析，通常需要高信噪比测量。此外，某些气体样品的测量可能会受到仪器中存在的大气水蒸气和二氧化碳的影响，即使是通过氮气净化。由于NO气体的吸收带在水蒸气区，而二氧化氮、二氧化碳和CO气体的吸收带靠近二氧化碳吸收区，因此分析尤其困难。使用全真空仪器系统，可以完全消除光路中的水蒸气和二氧化碳，即使在低浓度下也可以完成这些气体成分的测量。

本申请说明中介绍的FT/IR-6000系列全真空气体分析系统在样品室中集成了一个特殊的气室，使整个光路在气室就位的情况下保持在全真空下。该全真空模型使得即使在0.2ppm水平下也能够定量H2O的浓度。

Figure 1: ATR-500/Mi?ATR crystal plate (Upper right: Prism and liquid cell) Characterized by wavelengths longer than the mid-infrared region, the far-infrared region is also referred to as the terahertz region. In recent years, this region has been used to evaluate crystal polymorphs for pharmaceuticals and semiconductor device materials, as well as for archaeological research applications, including the study of inorganic pigments. Light in the far-infrared region (terahertz waves) corresponds to hydrogen bonding and Van der Waals forces believed to hold the key to an understanding of the functional

Gas Analysis System using Full Vacuum Type FT/IR (Trace amount of H2O in N2 gas) (1/2) No. 230TR0187-E The analysis of low concentration gases using long pathlength gas cells has been reported previously, however, it can be difficult to accurately quantitate gases at low concentrations when the absorption peaks of the target gas overlap with the peaks of atmospheric water vapor or, when the target gas itself is H2O or CO2, which are presnet in the atmosphere. This is because even with a vacuum FT-IR instrument, it was not possible to evacuate the sample chamber with the long pathlength cell present. The full vacuum gas analysis system introduced in this application note has a special gas cell integrated into the sample chamber, allowing the entire light path to remain under full vacuum with the gas cell in place. This full vacuum model makes it possible to quantitate concentrations of H2O even at the 0.1 ppm level. For the measurement, there are separate vacuum lines for evacuation of the FT-IR instrument and the gas cell, with independent evacuation capability for the separate components. Adding a vacuum gauge to the gas cell makes it possible to control extremely
