SAMPLE FABRICATION DEVICE, AND SAMPLE FABRICATION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a sample fabrication device capable of stable supply of a standard substance containing a trace amount of samples.SOLUTION: A sample fabrication device comprises: a conductive substrate which is coated by an insulator, and provided with a through-hole; an electrode pair arranged so as to sandwich the conductive substrate; and a current detector which is connected to the electrode pair and measures changes of an ion current value when the sample passes through the through-hole. The molecule number of the sample having passed through through-hole is measured by measuring changes of an ion current value. Thus, a sample whose molecule number was measured is fabricated.
