Analytical instruments, methods, and components
Variable temperature analytical instrument components are provided that can include: a conduit configured to extend between two chambers having different pressures; and a first mass about a section of the conduit, wherein the first mass is maintained at a first temperature. Variable temperature analytical instruments are provided that can include: a sample chamber configured to be operably coupled to a heat or cold source via one or more conduits; an interface component configured to engage the one or more conduits with the sample chamber, the interface comprising a conduit configured to extend between two chambers having different pressures; and a first mass about a section of the conduit, wherein the first mass is maintained at a first temperature. Methods for maintaining temperatures within a variable temperature analytical instrument are also provided. These methods can include maintaining a temperature within a conduit extending between two components of the instrument while each component is maintained at different pressures.
1. A variable temperature analytical instrument component comprising:
a thermally conductive conduit configured to extend between two chambers having different independent pressures;
a pressure barrier component between the two chambers and housing the thermally conductive conduit; and
a first mass about a section of the pressure barrier component, wherein the first mass is maintained at a first temperature.
2. The variable temperature analytical instrument component of claim 1 wherein the analytical instrument component is an analysis component interface.
3. The variable temperature analytical instrument component of claim 1 further comprising a second mass about the first mass, wherein the first mass is maintained at the first temperature and the second mass is maintained at a second temperature greater than the first temperature, but less than ambient temperature.
4. The variable temperature analytical instrument component of claim 3 further comprising an insulating member between the first and second masses.
5. The variable temperature analytical instrument component of claim 3 further comprising an insulating member extending from the second mass and engaging an ambient temperature mass.
6. The variable temperature analytical instrument component of claim 1 wherein the first mass extends longitudinally along the section of conduit.
7. The variable temperature analytical instrument component of claim 6 wherein the first mass extends a first thickness laterally from the conduit.
8. The variable temperature analytical instrument component of claim 7 wherein the first distance is greater than the second distance.
