在红外制样技术中,13mm KBr压模是最常用的。通常对于定性分析,13mm KBr压模需要使用1-1.5mg的样品。如果使用内孔为11×3mm的硬纸框,可将样品量减少至0.3～0.5mg。但是,使用硬纸框制备的KBr锭片往往有几个缺点:1.矩形样品区与纸框的结合部透明度较差,因此会增加光谱的本底吸 In the infrared sample preparation technology, 13mm KBr stamper is the most commonly used. Typically for qualitative analysis, a 1-1.5 mg sample is required for a 13 mm KBr die. If you use a hole in the 11 × 3mm cardboard frame, the sample can be reduced to 0.3 ~ 0.5mg. However, KBr spindles made using cardboard boxes tend to have several disadvantages: 1. The junction of the rectangular sample area and the paper frame is less transparent and therefore increases the background absorption of the spectrum
