This presentation focuses on Omnic software usage.,样品制备,Samples Preparation,样品干燥处理后与溴化钾研磨，压片机压片。,Tabletting samples and potassium bromide mixture after dried.,干燥方法,Methods,烘箱,Oven,真空干燥,Vacuum Desiccation,样品测量,Samples Measure,Omnic,软件是,Nicolet,公司傅立叶红外光谱仪的软件包，用其可以方便地对光谱进行采集、处理、简单定量分析等操作。,Omnic is the software package of Nicolet FT-IR. It could be used to collect and process data and do some simple quantitative analysis.,操作界面,Operator Interface,打开,Omnic,软件时出现的界面,采集样品,Collect Sample,采集背景,Collect Background,实验设置,Experiment Setting,吸光度,Absorbance,透过率,Transmittance,自动基线校正,Auto-baseline Correct,标峰,Find Peaks,删除,Clear,打开某一文件后的界面，这是一张溴化钾背景,Potassium Bromide Background,实验设置,Experiment Setting,:,扫描次数、分辨率、大气背景扣除、自动保存、,背景处理,采集样品,Sample Collection,：默认,y,轴为透过率,%,基线校正,Baseline correction,：首先将纵轴变为吸光度。,基线校正,Baseline Correction,：而后点击,自动基线校正,按钮。,基线校正,Baseline Correction,：点击,透过率,使纵轴返回透过率，红线部分即为校正后谱图。,基线校正,Baseline Correction,：点击校正线，,删除,，完成。,标峰,Find Peaks,：灵敏度调整，灵敏度越高，峰值显示越多。完成后点击,替代,按钮。,标峰,Find Peaks,：峰值标注显示不完整，点击调整。,OK.,保存文件,Save files,：文件,-,另存为。,.SPA,为软件识别原始文件；,.CSV,为,Excel,可识别工作表文件；,.WMF,为图片文件。三者都保存。,保存文件示例。,Examples,完成,0,Thanks for your attention,请提宝贵意见！,
