A method of determining glycated hemoglobin is provided, by which a ratio of the glycated hemoglobin in a sample can be determined accurately and easily. The ratio of glycated hemoglobin can be determined by degrading a glycated hemoglobin in a whole blood sample selectively with a protease to give a glycated hemoglobin degradation product`; causing a redox reaction between a glycation site of the glycated hemoglobin degradation product and a fructosyl amino acid oxidoreductase; and determining this redox reaction. Further, as shown in FIG. 1, in a whole blood sample, there is a correlation between the ratio of the glycated hemoglobin determined by this method and an HbA1c concentration. Thus, without determining the glycated alpha-amino group as a characteristic structure of HbA1c, an amount of HbA1c can be determined accurately and easily from the determined ratio of the glycated hemoglobin.

In a volumetric gas adsorption measuring method, an initial dead volume of the sample cell and an initial dead volume of a reference cell at the same time point are preliminarily determined. When the gas adsorption on the solid sample is to be measured, a change in the dead volume of the sample cell is calculated on the basis of an internal gas with the sample cell and reference cell immersed in a pressure of the reference cell measured at this time point cryogenic fluid temperature bath, the initial dead volume of the reference cell, and an initial gas pressure of the reference cell measured at a time point of the measurement of the initial dead volume of the reference cell. Then, the initial dead volume of the sample cell preliminarily measured is corrected on the basis of the change in the dead volume of the sample cell for the calculation of the amount of the gas adsorbed on the solid sample.

A card reader that transports a card having a magnetic strip with a drive means to read and write information on the card that includes prehead for detecting the insertion of the card by searching the presence of the magnetic information recorded on the magnetic strip, and a card detecting switch for detecting the card. When the card detecting switch determines that a card is present, the prehead searches the magnetic information. When the card detecting switch does not detect a card, the card is distinguished as a specially-shaped card.

A photovoltaic devices inspection apparatus and method of determining defects in photovoltaic devices that uses electroluminescence can find both the quality of the photovoltaic devices from the state of electroluminescence and the possibility of the photovoltaic devices becoming defective in the future by applying constant electric current to the photovoltaic devices causing electroluminescence of the photovoltaic devices (S7), photographing the light emitted from each photovoltaic cell of the photovoltaic devices (S10), dividing the photographed image of the photovoltaic cell into a bright region and dark region by using a threshold value and displayed as an enhanced image by binarization, analyzing as classifying each photovoltaic cell defect according to defect types and comparing a shape of the dark region with the defect types (S50), determining the existence of the defect to perform a positive-negative quality judgment on the photovoltaic devices, and displaying images of the problematic regions for visual inspection (S16).

A method of determining Hb is provided, by which an amount of Hb can be determined easily and accurately without fear of damage to the environment. Hemoglobin in a sample is denatured with a tetrazolium compound to give denatured hemoglobin, and an amount of an optical change in the sample is measured at an absorption wavelength specific to the denatured hemoglobin. Using the amount of the optical change thus measured, an amount of the hemoglobin in the sample can be determined. The amount of the optical change preferably is measured at a wavelength in a range from 520 to 670 nm. According to this method, an amount of Hb can be determined with high accuracy as shown in FIG. 1.
