Twin-calorimeter chip for the Flash DSC

 


Twin-calorimeter chip on ceramic base plate (standard sensor UFS1)

Mettler-Toledo in Switzerland and Xensor have together successfully developed the sensing heart in an instrument for Fast Differential Scanning Calorimetry (Fast DSC):
one-time-use twin-calorimeter chips on a ceramic base plate.

Standard sensor (UFS1)
The UFS1 chip measures 5.0 x 3.3 mm2 and has two membranes of 1.7 x 1.7 mm2 with each a 0.5 mm ø sample area. The ceramic base plate measures 24 x 24 mm2.
The UFS1 chip allows power-compensated operation at controlled heating rates of up to 40 000 K/s (2 400 000 K/min) and controlled cooling rates of 4 000 K/s (240 000 K/min).
Masses typically between 20 ng and 2 000 ng. The temperature range is -100 to 450 °C for the standard sensor (UFS1).

High temperature sensor (UFH1)
The high temperature UFH1 chip measures 3.75 x 3.0 mm2 and has two membranes of 0.8 x 0.8 mm2 with each a 0.09 mm ø sample area.
The UFH1 chip allows power-compensated operation at controlled heating rates of up to 50 000 K/s (3 000 000 K/min) and controlled cooling rates of 40 000 K/s (2 400 000 K/min).
Masses typically between 5 ng and 5 000 ng.The temperature range is -100 to 1000 °C for the high-temperature sensor (UFH1).

Applications are foreseen in areas such as:
-  polymer analysis.
-  pharmaceutical analysis.
-  explosives analysis.
-  metal analysis.
