Abstract

本发明涉及用于量热测量的样品小瓶(1)。本发明教导了小瓶材料(1’)为质量轻的,以及在小瓶的外部,小瓶至少部分地涂覆有红外反射涂层。5本发明还涉及用于与小瓶(1)一起形成安瓿(5)的盖子(4)。

Description

用于量热测量的样品小瓶
技术领域
本发明涉及一种用于量热测量的样品小瓶和用于该样品小瓶的盖子。
背景技术
通常在使用独立隔离且处于热态的单样品室的设备中执行等温量热测量。为了增加样品的生产量从而应对并适应普通实验室库存,可以使用单板式多通道恒温量热器(等温量热仪),其对于多个样品小瓶使用一个共同室。这允许在典型实验室环境下具有更快且更有效的样品生产量。
发明内容
问题
通过使用标准化微量滴定板布置(诸如ANSI/SBS1-2004标准中所述)而施加的尺寸限制使得生成热量的样品小瓶彼此紧靠并且使得样品小瓶与相邻的热流传感器紧靠。微量滴定板的各样品之间将由空气进行隔离。
样品之间的红外热辐射造成导致不期望的交叉样品加热和样品精度损失的风险。
解决方案
从用于量热测量的样品小瓶的观点出发并以解决上述问题中的一个或多个为目的,本发明教导了:小瓶材料是质量轻的;并且在该小瓶的外部,该小瓶至少部分地涂覆有红外反射涂层。
通过利用质量轻的样品小瓶材料,将发生从样品小瓶到热流传感器的快速热传递。用红外反射涂层涂覆样品小瓶将小瓶中生成的热量反射回小瓶中并且使邻近小瓶中生成的热量转向。最终结果是,增加多小瓶恒温量热器中特定样品信号的完整性。
本申请建议:小瓶材料包括但不限于钛合金;红外反射涂层包括但不限于氮化钛。
当利用以下原则(即,测量到传递能量的热量流通过样品小瓶的与安装有散热器的传感器相接触的侧面从该样品小瓶流到该传感器)时,本申请提出:小瓶的该侧面没有红外反射涂层以便增加传到热传感器的热量流。
本申请建议:小瓶的底部是该小瓶的与位于样品组件底部的传感器相接触的侧面。
红外反射涂层优选地物理性(mechanically,机械方面)稳定并且化学惰性高,例如,金(Au)或陶瓷复合物,所述陶瓷复合物包括但不限于氮化钛(TiN),诸如来自欧瑞康巴尔查斯(OerliconBalzers)的A,并且建议使用在0.5μm与4μm之间的涂层厚度。
为了提供具有本发明的小瓶的有利特性的完整安瓿,本发明还涉及用于与本发明的小瓶一起形成安瓿的盖子。盖子材料为质量轻的,并且在盖子的外部,盖子至少部分地涂覆有红外反射涂层。
盖子材料包括但不限于钛合金;红外反射涂层包括但不限于氮化钛。
红外反射涂层物理性稳定并且化学惰性高,诸如金(Au)或陶瓷复合物,所述陶瓷复合物包括但不限于氮化钛,并且具有在0.5μm与4μm之间的涂层厚度。
优点
根据本发明的小瓶或方法的优点是,最终结果为,通过除了与传感器接触的小瓶侧面之外的小瓶侧面上的红外反射材料的选择性应用,增加了从样品到传感器的小瓶间热量传递。
本发明的样品小瓶特别有利于用在多通道量热测量中,因为通过尽可能地减少通过空气对邻近小瓶和传感器的热量辐射而降低内部样品红外辐射。
附图说明
现在将参照附图,详细描述本发明的样品小瓶,附图中:
图1是具有盖子的本发明的样品小瓶的横截面视图;
图2是具有涂层的小瓶的一部分的示意性简化横截面放大图;以及
图3是具有涂层的盖子的一部分的示意性简化横截面放大图。
具体实施方式
将参照图1描述本发明,图1示出了用于量热测量的样品小瓶1,其中,小瓶材料1’为质量轻的。图2示出了在小瓶1的外部,小瓶1至少部分地涂覆有红外反射涂层2。
该小瓶适用于这样的测量,其中测量到传递能量的热量流通过样品小瓶的与安装有散热器的传感器接触的侧面1a从该样品小瓶流到传感器,并且建议小瓶的该侧面1a没有红外反射涂层。图1示出了一实施例,其中小瓶1的底部是该小瓶的与传感器3接触的侧面1a。
本申请建议:小瓶材料1’包括但不限于钛合金;红外反射涂层2包括但不限于氮化钛。
优选地,红外反射涂层2物理性稳定并且化学惰性高,诸如金(Au)或陶瓷复合物,所述陶瓷复合物包括但不限于氮化钛。
本申请还建议红外反射涂层具有在0.5μm与4μm之间的涂层厚度A。
图1还示出了用于与本发明的小瓶1一起形成安瓿5的盖子4。盖子材料4’为质量轻的,并且图3示出了在盖子4的外部,盖子4至少部分地涂覆有红外反射涂层6。
盖子材料4’包括但不限于钛合金;红外反射涂层6包括但不限于氮化钛。
红外反射涂层6物理性稳定并且化学惰性高,诸如金(Au)或陶瓷复合物,所述陶瓷复合物包括但不限于氮化钛,并且具有在0.5μm与4μm之间的涂层厚度B。
应当理解,本发明不限于以上所述和示出的本发明的示例性实施例,可以在如由所附权利要求所限定的本发明的范围内做出修改。
