Description

用于红外光谱仪的保温筒
技术领域:
本实用新型涉及一种用于红外光谱仪的保温筒。
背景技术:
对于通过红外光谱仪进行光谱分析的化学物质,经常需要研究化学物质的结构随着温度变化的情况,现有的红外光谱仪未配备保温配件,因而不能研究在温度变化的情况下试样相变、固化、老化时分子间相互作用、化学反应等物理和化学过程。室温下为固态的试样,在较高的温度下可能会发生相转变,或者由玻璃态变成高弹态、皮革态和粘流态。随着温度的升高,试样的红外光谱会发生变化。谱带的峰位、峰形、峰高和峰宽可能会发生变化。原有的谱带可能会消失,还可能出现新谱带。试样可能从有序的排列状态转变成无序状态。有氢键的试样体系可能会破坏,试样熔化导致晶格破坏也会引起红外光谱的变化。可见,变温红外光谱已经成为红外光谱学的重要组成部分。另外,变温红外光谱附件温度可以从室温升到几百度,要想测试不同温度下样品的红外光谱,变温红外光谱附件,除了加热系统外,还需要配备保温系统,即可每隔固定温度测定一次光谱,由于存在温度梯度,达到测量温度后,需要恒温5~10min。如果温度上升的速率无法控制,不能保持稳定的恒温,测试出来的光谱就不是该温度下试样的光谱,试样光谱的变化将无法准确显示物理和化学过程。
实用新型内容:
本实用新型的目的是提供一种用于红外光谱仪的保温筒。
上述的目的通过以下的技术方案实现:
一种用于红外光谱仪的保温筒,其组成包括:筒壁,所述的筒壁的外壁形状是与红外光谱仪插槽形状相适应的外壁形状,所述的筒壁两端分别安装有筒盖,所述的筒壁具有进气孔、出气孔、测温孔,所述的筒盖中部具有通孔。
所述的用于红外光谱仪的保温筒,所述的筒壁采用保温玻璃钢,所述的筒盖与所述的筒壁通过螺纹连接。
有益效果:
本实用新型的优点在于经济方便实用,对试样片进行红外光谱测试时直接将本实用新型插入红外光谱仪的插槽内即可,而无需将试样片固定在专用配套元件上再安装到红外光谱仪的样品仓内,省去了购买专用配套元件昂贵费用。同时,可通过向本实用新型内注入恒温气体来调节实验温度。
本实用新型的筒壁为采用经硅烷偶联剂对具有低导热系数的六钛酸钾晶须、二氧化硅纳米进行表面处理后加入到不饱和聚酯、环氧树脂卷材涂料中使保温玻璃钢筒壁具有良好的保温隔热效果;气、液、固三种状态的试样都可以进行测试;用于夹持试样的溴化钾片可以用压片机制成,减少了试验成本。
附图说明:
附图1是本实用新型的主剖视图。图中,7为试样片。
具体实施方式:
实施例1:
一种用于红外光谱仪的保温筒,其组成包括:筒壁1,所述的筒壁的外壁形状是与红外光谱仪插槽形状相适应的外壁形状,所述的筒壁两端分别安装有筒盖2,所述的筒壁具有进气孔3、出气孔4、测温孔5,所述的筒盖中部具有通孔6。所述的筒盖与试样片连接,所述的试样片与所述的筒壁连接。试样片夹在筒盖与筒壁之间。
实施例2:
根据实施例1所述的用于红外光谱仪的保温筒,所述的筒壁采用保温玻璃钢,所述的筒盖与所述的筒壁通过螺纹连接。所述的保温筒的筒内径是10-12mm。
