Abstract: A substrate for biochips has a substrate surface having a reaction region capable of reacting with biological substances and a non-reaction region not reacting with the biological substances, sunken bottomed wells formed in the substrate surface, and a layer of a material capable of reacting with the biological substances having a surface exposed only at the bottoms of the bottomed wells, the exposed surface forming the reaction region.

Abstract: There are provided a mass spectrum analysis device, a mass spectrum analysis method, and a mass spectrum analysis program capable of accurately analyzing a mass spectrum. The mass spectrum device analyzes a mass spectrum measured for a plurality of samples. The mass spectrum device includes peak position detection means 14 for detecting a peak position where the mass spectrum is at its peak, and coincidence degree calculation means 15 for calculating the coincidence degree of peaks according to the number of peak positions detected in a plurality of mass spectra that is contained in a window having a width for a mass number.

Abstract: A copper alloy for use in the manufacture of a radiator fin contains 10 to 150 ppm of tellurium and 20 to 110 ppm of phosphorus, both by weight, as well as copper and unavoidable impurities.
