The present invention comprises: a step of applying a liquid composition for forming a PZT ferroelectric film; a step of drying the film applied with the liquid composition; a step of irradiating UV rays onto the dried film at a temperature of 150 to 200&#xb0; C. in an oxygen-containing atmosphere; and after the application step, the drying step, and the UV irradiation step once, or more times, a step of firing for crystallizing a precursor film of the UV-irradiated ferroelectric film by raising a temperature with a rate of 0.5&#xb0; C./second or higher in an oxygen-containing atmosphere or by raising a temperature with a rate of 0.2&#xb0; C./second or higher in a non-oxygen containing atmosphere, followed by keeping the temperature at 400 to 500&#xb0; C. An amount of liquid composition is set such that thickness of the ferroelectric film be 150 nm or more for each application and ozone is supplied during UV irradiation.

Method for forming PZT ferroelectric film

To improve the detection sensitivity, detection accuracy, and reproducibility when electrostatic discharge is generated in a sample solution and analysis is performed using light emission in the generated plasma. A flow channel, which has cylindrical main portions each expanding conically from a narrow portion, is filled with a conductive sample solution, and an electric field is applied to the flow channelto generate plasma in the generated air bubbles, so that the resulting light emission is measured.

Method for concentrating and collecting small quantities of fetal nucleated red blood cells contained in the maternal blood. The method for concentrating and collecting nucleated red blood cells from the maternal blood comprises: (i) subjecting the maternal blood to a first density-gradient centrifugation and collecting a cell fraction containing nucleated red blood cells; (ii) treating the cell fraction containing nucleated red blood cells so as to selectively changes the density of the nucleated red blood cells from that of the white blood cells; and (iii) subjecting the treated cell fraction containing the nucleated red blood cells to a second density-gradient centrifugation so as to collect a fraction containing nucleated red blood cells.

To improve detection sensitivity, detection accuracy, and reproducibility when electric discharge is caused in a sample solution to perform analysis with light emission in the plasma,

A method for evaluating the quality of a blood sample, comprising the steps of: mixing labeled anti-cortisol antibodies with a blood sample to be subjected, to conduct the antigen-antibody reaction of the labeled anti-cortisol antibody with cortisol contained in the blood sample, developing a mixture obtained in the above step on an immunochromatographic test strip having a substrate on which cortisol is immobilized to cause the antigen-antibody reaction of the labeled anti-cortisol antibodies which are free in the mixture with the cortisol immobilized on the substrate, thereby bonding the antibody to the cortisol, determining the amount of the labeled anti-cortisol antibodies bonded to the cortisol in the above step, and evaluating whether or not the blood sample has a quality suitable for suprarenal vein sampling test on the basis of the amount of the labeled anti-cortisol antibodies determined in the above step.

Method for evaluation of quality of blood sample

A method for generating plasma and a method for elemental analysis, each comprising the steps of providing a narrow portion in a flow channel made of an insulation material, the narrow portion having a cross-sectional area markedly smaller than a cross-sectional area of the flow channel; filling the flow channel and the narrow portion with a conductive liquid, and thereafter applying an electric field to the narrow portion, to conduct the electric field through the narrow portion, thereby generating plasma at the narrow portion. An apparatus for generating plasma, the apparatus for generating plasma comprising a narrow portion in a flow channel made of an insulation material, the narrow portion having a cross-sectional area markedly smaller than a cross-sectional area of the flow channel; and a means of applying an electric field to the narrow portion to conduct the electric field through the narrow portion; and an apparatus for emission spectroscopic analysis comprising the apparatus for generating plasma as defined above.
