    • A thermal-gradient osmometer includes a substrate (20) spanning two independently variable temperature zones (21, 22) separated by a gap (23), and a plurality of sample rows (24a-24d) provided on or in the substrate (20). The zones (21, 22) establish a thermal gradient across the substrate (20). In operation, an unknown solution whose phase transition temperature is desired is provided in a first sample row. Next, a first and a second solution having respectively, higher and lower phase transition temperatures than the unknown solution are placed in a second and third sample rows, respectively. The three sample rows are then exposed to the thermal gradient so as to cause a portion of the three solutions to undergo a phase transformation while generating respective first, second and third solid-liquid interfaces in their respective sample rows. The phase transition temperature of the unknown solution is determined based on the position of the third interface relative to the first and second interfaces.
    • 热梯度渗透压计包括跨越由间隙(23)分开的两个独立变化的温度区(21,22)的衬底(20)和设置在衬底(20)上或衬底(20)中的多个样品排(24a-24d) 。 区域(21,22)跨越衬底(20)建立热梯度。 在操作中,在第一样品行中提供需要相变温度的未知解决方案。 接下来,具有分别比未知溶液更高和更低的相变温度的第一和第二溶液分别放置在第二和第三样品行中。 然后将三个样品行暴露于热梯度,以便使三个溶液的一部分经历相变,同时在其各自的样品行中产生相应的第一,第二和第三固液界面。 基于第三接口相对于第一和第二接口的位置来确定未知解的相变温度。
