Differential thermal detection and differential flow microcalorimetry
Abstract
Abstract DIFFERENTIAL DETECTION IN WHICH A REFERENCE CELL IS USED FOR COMPARISON PURPOSES WITH AN OBSERVATION CELL IN WHICH A PHENOMENON TAKES PLACE. DETECTION IS OBTAINED BY MEANS OF A SINGLE THERMO-ELECTTRIC SENSOR. THE SENSOR IS MOUNTED TO A COMMON CONDUIT OF HEAT EXCHANGE LIQUID FLOW CIRCUIT WHICH USES TWO BRANCH CIRCUITS, ONE ASSOCIATED WITH EACH CELL. A FLOW CHOPPING ELEMENT AT THE INLET ENDS OF THE BRANCH CIRCUITS PROVIDES COMPLEMENTARY PERIODIC FLOW HEAT EXCHANGE LIQUID SEGMENTS IN THE BRANCH CIRCUITS. THESE SEGMENTS ARE THEN FED INTO A COMMON RETURN CIRCUIT WHERE THE SENSOR IS INSTALLED. A DIFFERENTIAL FLOW MICROCALORIMETER USING COUNTER FLOW HEAT EXCHANGERS THROUGH WHICH A LIQUID IS CIRCULATED IN COMPLEMENTARY PERIODIC FLOW SEGMENTS. THE SEGMENTS ARE COMBINED IN A COMMON RETURN TUBE WHERE INSTANTANEOUS TEMPERATURE VARIATIONS ARE DETECTED AND THEN ANALYSED.
