Pressure Perturbation Calorimetry Instruments And Methods

View page
US Patent:
6485173, Nov 26, 2002
Filed:
May 16, 2001
Appl. No.:
09/858622
Inventors:
Valerian V. Plotnikov - Sunderland MA
John F. Brandts - Leeds MA
J. Michael Brandts - Holyoke MA
Assignee:
MicroCal, Inc. - Northhampton MA
International Classification:
G01K 1700
US Classification:
374 10, 374 31, 374 55, 374 54
Abstract:
A method of determining a thermal coefficient of expansion of a substance, the method including providing a first liquid holder containing a solution including the substance, and a second liquid holder containing a liquid in which the substance is not present; applying a pressure perturbation to the solution in the first liquid holder and to the liquid in the second liquid holder at a known temperature; determining a differential heat effect between the first and second liquid holders in response to the pressure perturbation; calculating, from the differential heat effect, the heat effect of the substance in response to the pressure perturbation; and determining, from the calculated heat effect, the thermal coefficient of expansion of the substance at the known temperature.

US Patent:
6513969, Feb 4, 2003
Filed:
Sep 24, 2001
Appl. No.:
09/961872
Inventors:
Valerian V. Plotnikov - Sunderland MA
John F. Brandts - Leeds MA
J. Michael Brandts - Holyoke MA
Assignee:
Microcal, LLC - Northampton MA
International Classification:
G01K 1702
US Classification:
374 10, 374 31, 374 12
Abstract:
A calorimeter that includes a sample cell, a reference cell, a pressure system that applies a variable pressure to the sample cell, and a pressure controller that controls the pressure applied by the pressure system to the sample sell. By applying identical pressure perturbations to both the sample and reference cells over a range of temperature, the calorimeter can be used to accurately calculate both the thermal coefficient of expansion of various substances, and the volume change of molecules undergoing a structural transition.

US Patent:
6869214, Mar 22, 2005
Filed:
Jan 30, 2003
Appl. No.:
10/354934
Inventors:
Valerian V. Plotnikov - Sunderland MA, US
John F. Brandts - Leeds MA, US
J. Michael Brandts - Holyoke MA, US
Assignee:
MicroCal LLC - Northampton MA
International Classification:
G01K017/00
G01N025/00
US Classification:
374 31, 374 10, 374 33, 374 11
Abstract:
A calorimeter that includes a sample cell, a reference cell, a pressure system that applies a variable pressure to the sample cell, and a pressure controller that controls the pressure applied by the pressure system to the sample cell. By applying identical pressure perturbations to both the sample and reference cells over a range of temperatures, the calorimeter can be used to accurately calculate both the thermal coefficient of expansion of various substances, and the volume change of molecules undergoing a structural transition.

Ultrasensitive Differential Microcalorimeter

View page
US Patent:
58137637, Sep 29, 1998
Filed:
Oct 11, 1996
Appl. No.:
8/729433
Inventors:
Valerian V. Plotnikov - Sunderland MA
John F. Brandts - Leeds MA
J. Michael Brandts - Holyoke MA
Assignee:
Microcal Incorporated - Northhampton MA
International Classification:
G01N 2520
US Classification:
374 11
Abstract:
A calorimeter includes sample and reference cells, a thermal shield surrounding these cells, a heating device thermally coupled to the thermal shield, temperature sensors for monitoring a temperature of the shield and a temperature differential between the shield and the cells, and a control system. The control system has an output line connected to the heating device and input lines to receive signals from the temperature sensors. The control system is configured to generate on its output line an output signal which is a function of both the input signals received on its input lines.

Ultrasensitive Differential Microcalorimeter With User-Selected Gain Setting

View page
US Patent:
59676590, Oct 19, 1999
Filed:
Sep 16, 1998
Appl. No.:
9/154055
Inventors:
Valerian V. Plotnikov - Sunderland MA
John F. Brandts - Leeds MA
J. Michael Brandts - Holyoke MA
Assignee:
MicroCal, Incorporated - Northampton MA
International Classification:
G01N 2520
US Classification:
374 11
Abstract:
A differential calorimeter includes sample and reference cells, a thermal shield surrounding these cells, heating devices thermally coupled to the thermal shield and the cells, a temperature monitoring system for monitoring temperature of the shield, cell temperatures and temperature differentials between the cells and the shield, and a control system. The control system has input lines to receive signals from the temperature sensors and output lines connected to the heating devices. The control system is configured to generate output signals for control of heating devices. A gain setting and scan rate are selected by means of a user interface. The output control signals are functions of input temperature signals and the user-selected gain setting, and also functions of input temperature signals and the user-selected scan rate using a mapping function stored in memory.
