A calorimeter and method is also provided, including a sample cell, a reference cell, a thermostat in thermal communication with the sample cell and the reference cell, a first conductive wire, the first conductive wire having a first end connected to the thermostat and a second end connected to the sample cell, and a second conductive wire, the second conductive wire having a first end connected to the thermostat and a second end connected to the reference cell.

Hybrid calorimeter cell

Described is a differential scanning calorimeter (DSC) instrument capable of performing analyses of multiple samples at the same time. Some embodiments of DSC instruments described herein include a thermal substrate that provides a substantially uniform temperature across a surface of the substrate. A plurality of DSC units is in thermal communication with the substrate, for example, by mounting the units directly to the surface of the substrate. Each DSC unit includes a second thermal substrate for further thermal isolation, and a reference platform and sample platform to receive a reference cell and a sample cell, respectively. A thermoelectric device is disposed between each platform and the second thermal substrate. Optionally, the reference and sample cells may be disposable chips that can be discarded after measurement are performed, thereby reducing or eliminating the need to clean instrument components to prevent cross-contamination for subsequent instrument operation.

High sample throughput differential scanning calorimeter

A calorimeter cell of a calorimetry system is provided, having a cell body having an internal region for receiving a first substance, the cell body being comprised of a chemically inert material, and a thermally conductive layer at least partially surrounding the chemically inert cell body. Furthermore, an associated calorimeter and method is also provided, including a sample cell, a reference cell, a thermostat in thermal communication with the sample cell and the reference cell, a first conductive wire, the first conductive wire having a first end connected to the thermostat and a second end connected to the sample cell, and a second conductive wire, the second conductive wire having a first end connected to the thermostat and a second end connected to the reference cell.
