在红外光谱测试中对某些能升华而又对空气敏感的金属有机化合物可以经过真空处理得到合适的测试样品。但这种方法不适用于不能升华的样品。一般固体样品适用的红外常规压片和糊状制样方法,因其操作过程较长,故在空气敏感的样品制样中必需有保护环境。在上述二种方法中,以糊状法制样更适合于空气敏感样品。这时,油层包复在样品粒子表面,起着隔离空气的作用,使样品在光谱测量过程的短时间中免于(或不致很快)破坏。但油糊(石蜡油或氟油)制
In infrared spectroscopy, some sublimation and air-sensitive metal-organic compounds can be vacuum-treated to obtain a suitable test sample. However, this method does not apply to samples that can not be sublimated. General solid samples suitable for infrared conventional tabletting and pasty sample preparation method, because of its long operation, it is necessary in the air-sensitive sample preparation to protect the environment. In the above two methods, the paste-like sample preparation is more suitable for air-sensitive samples. At this point, the oil layer wraps around the surface of the sample particles, isolating the air from the sample, preventing the sample from being damaged (or not quickly) during a short period of spectroscopic measurement. But paste (paraffin oil or fluorine oil) system
