Abstract
A nozzle-type analysis apparatus for sucking a sample solution in a sample vessel for analyzing the sample solution. A sample suction nozzle for sucking the sample solution stored in the sample vessel and a solution component sensor having a sensor forming portion formed integrally with a front end portion of the sample suction nozzle to be inserted into the sample vessel are provided. The integral structure of the sample suction nozzle and the solution component sensor has a size capable of being inserted into the sample vessel, the solution component sensor having a sensor output portion effected with a water-resistant insulation layer. A hydrophobic film is further formed on the surface of the sensor a coat treatment. A sample flow shut-out valve is disposed in the sample flow passage at a portion between the front end of the sample suction nozzle and the sensor forming portion of the solution component sensor.
