SOLUTION: A calibration process part 25 of a personal computer 2 controls a differential scanning calorimeter main body 1 in accordance with an instruction from a worker or a measuring program, and processes data. More specifically, the process part receives data measured by a thermocouple of the main body 1 and processing to obtain calibration data on the basis of the received data and data of document values input from the outside. Upon completion of the processing, a calibration coefficient as the calibration result is set to a measurement processing part 24 and a calibration history of an executed calibration and the calibration result is automatically stored in a hard disk apparatus 21. The calorimeter is calibrated in accordance with the instruction of the worker to the processing part 25 and at the same time, a list and contents of previous calibration histories are read out from the apparatus 21, displayed and printed by a display 22 and a printer 23. In consequence, the calibration limit for parts and the reliability of measurement data can be judged easily.

Abstract:
PROBLEM TO BE SOLVED: To suppress the data quantity, while grasping accurately a sudden change, when analyzing, for example, a sample generating the sudden change after being left for long hours at a temperature. SOLUTION: An analyst sets beforehand data collection time intervals Δt1, Δt2 corresponding to the magnitude of a signal change. When analysis is started, a differential value of a detection signal is detected, and it is determined whether the value is over a threshold or not. When the differential value is below the threshold, measurement data are stored at Δt1 intervals in a data file, and when the differential value is over the threshold, the measurement data are stored at shorter Δt2 intervals in the data file. Hereby, while suppressing the data quantity in one data file corresponding to the analysis of one sample, measurement data for showing the mode of the sudden change can be also surely collected.

Abstract:
PROBLEM TO BE SOLVED: To provide an automatic apparatus for thermogravimetry advantageous in cost capable of accurately discriminating whether or not a sample cell is properly placed on a sample measuring part without fear of an occurrence of a discrimination error due to a malfunction of a sensor or a mounting position of the sensor. SOLUTION: Outputs of a weight measuring mechanism 7 engaged to the sample measuring part 4 are read before and after conveying the sample cell 1 onto the sample measuring part 4 by a cell conveying mechanism 12 for discriminating whether or not the sample cell 1 is properly placed on the sample measuring part 4 from a change of these outputs. By this, the sensor for detecting an existence of the sample cell 1 becomes unnecessary and the occurrence of the discrimination error due to its malfunction or its mounting position is prevented.
Abstract:
PROBLEM TO BE SOLVED: To enable the objective and accurate analysis of the deterioration, etc., of a device by extracting only noise components from baseline measurement signals and detecting the level of the noise components. SOLUTION: A differential scanning calorimeter main body 1 converts a difference in temperature measured by a thermocouple into a digital signal and outputs it as a temperature difference signal, and at the time of baseline measurement, the temperature difference signals are sent to a moving average processing part 2 and an adder 3. The moving average processing part 2 takes the moving average of the temperature difference signals, performs smoothing, and extracts only low-frequency components. In the adder 3, by subtracting the low-frequency components from the original temperature difference signals, only the high-frequency components of the temperature difference signals are extracted. An RMS processing part 4 calculates the RMS(root-mean-square) of the temperature difference signals and quantitatively detects the level of noise components. By this, as effects due to drifting and snaking are excluded, it is possible to diagnose the cause of device anomalies to a certain degree and to determine the size of noise objectively in a numerical value.

PROBLEM TO BE SOLVED: To prevent the increase of noises when a base line correction is carried out by subtracting a base line from thermal analysis data. SOLUTION: A thermal analysis is conducted beforehand without a sample loaded. A base line is obtained by a sampling part 2a which extracts thermal analysis data. The base line is smoothed by a smoothing part 2b, and the smoothed base line is stored in a data memory part 1. The thermal analysis data extracted by the sampling part 2a and the smoothed base line are read out from the data memory part 1 by a subtraction part 2c. A base line correction is executed to the thermal analysis data by subtracting the smoothed base line from the thermal analysis data.
