如何保证您的红外光谱仪正常工作?秘诀原来是这样!咱们首先要了解红外光谱仪的工作原理!傅立叶变换红外(FT-IR)光谱仪是根据光的相干性原理设计的,因此是一种干涉型光谱仪,它主要由光源(硅碳棒,高压汞灯),干涉仪,检测器,计算机和记录系统组成,大多数傅立叶变换红外光谱仪使用了迈克尔逊(Michelson)干涉仪,因此实验测量的原始光谱图是光源的干涉图,然后通过计算机对干涉图进行快速傅立叶变换计算,从而得到以波长或波数为函数的光谱图,因此,谱图称为傅立叶变换红外光谱,仪器称为傅立叶变换红外光谱仪。

2、如所用的是单光朿型傅里叶红外分光光度计上海11选5开奖结果(目前应用多),实验室里的CO2含量不能太高,因此实验室里的人数应尽量少,无关人员不要进入,还要注意适当通风换气。

4、红外光谱测定常用的试样制备方法是溴化钾(KBr)压片法(药典收载品种90%以上用此法),因此为减少对测定的影响,所用KBr应为光学试剂级,至少也要分析纯级。使用前应适当研细(200目以下),并在120℃以上烘4小时以上后置干燥器中备用。如发现结块,则应重新干燥。制备好的空KBr片应透明,与空气相比,透光率应在75%以上。

6、测定用样品应干燥,否则上海11选5开奖结果应在研细后置红外灯下烘几分钟使干燥。试样研好并具在模具中装好后,应与真空泵相连后抽真空至少2分钟,以使试样中的水分进一步被抽走,然后再加压到0.8~1GPa(8~10T/cm2)后维持2~5min。不抽真空将影响片子的透明度。

8、压片时,应先取供试品研细后再加入KBr再次研细研匀,这样比较容易混匀。研磨所用的应为玛瑙研钵,因玻璃研钵内表面比较粗糙,易粘附样品。研磨时应按同一方向(顺时针或逆时针)均匀用力,如不按同一方向研磨,有可能在研磨过程中使供试品产生转晶,从而影响测定结果。研磨力度不用太大,研磨到试样中不再有肉眼可见的小粒子即可。试样研好后,应通过一小的漏斗倒入到压片模具上海11选5开奖结果中(因模具口较小,直接倒入较难),并尽量把试样铺均匀,否则压片后试样少的地方的透明度要比试样多的地方的低,并因此对测定产生影响。另外,如压好的片子上出现不透明的小白点,则说明研好的试样中有未研细的小粒子,应重新压片。
