Abstract
In accordance with the invention, a liquid sample for thermal analysis is disposed within a receptacle having a bottom surface and side walls. The top edges of the side walls are bent towards the center of the receptacle. A sheet of flexible, transparent material substantially impermeable to the sample is disposed across the top edges of the side walls, and an open lid compresses an o-ring onto the sheet material, sealing it against the bent top edges of the receptacle. The bottom surface of the receptacle is advantageously coated with a a material not wetted by the sample such as a fluorcarbon.
Claims12
A method of confining a liquid sample within a container for thermal analysis, comprising the steps of:
- providing a receptacle, a lid wherein the lid has a top surface, a bottom surface opposite the top surface, and a sidewall, the bottom surface and sidewall defining an interior, a deformable sealant, and at least one sheet of material transparent to light of wavelength of from about 200 nanometers to about 900 nanometers, wherein the at least one sheet of material has a leak rate for the sample of less than about 1.5 wt. %/hr.;
- placing the sample of a liquid in the receptacle;
- placing the sheet of material in the lid, wherein the sheet of material is in contact with the bottom surface of the lid;
- placing the deformable sealant in the lid along the perimeter of the sheet of material;
- and
- compressing the lid onto the receptacle forming a container with the sample of the liquid sealed therein.
