摘要： A surface plasmon sensor comprises a sensor unit, which is provided with a transparent substrate and a metal film, and a coupler, which carries out light beam coupling and is separate from the sensor unit. A light beam is entered from a light beam entry portion of the coupler, and an attenuated total reflection angle .theta..sub.sp is detected from the light beam, which has been totally reflected from an interface between the transparent substrate and the metal film and has then been radiated out of a light beam radiating portion of the coupler. The sensor unit is supported by a sensor unit attachment such that a distance between the transparent substrate and the coupler may be kept to be equal to a predetermined value. The space between the transparent substrate and the coupler is filled with a refractive index matching liquid. Fitting of the sensor unit in the surface plasmon sensor is easy to carry out, and the relationship between positions of the sensor unit and the coupler can be kept constant.

摘要： A surface plasmon sensor comprises a prism, a metal film, which is formed on one surface of the prism and is brought into contact with a sample, and a light source for producing a light beam. An optical system causes the light beam to pass through the prism and to impinge upon an interface between the prism and the metal film such that various different angles of incidence may be obtained with respect to the interface. A photodetector detects an intensity of the light beam, which has been totally reflected from the interface, with respect to each of the various different angles of incidence. An electrode stands facing the metal film with a liquid sample intervening therebetween, and a DC voltage is applied across the electrode and the metal film. A substance contained in the liquid sample is thus analyzed quickly and with a high sensitivity.
