Nozzle-type analysis apparatus

An analysis apparatus for sucking a sample solution in a sample vessel for analyzing the sample solution comprising:

• a sample suction nozzle means having defined therein a channel through which a sample is suctioned;
• an elongated front end portion attached to the sample suction nozzle means for sucking the sample solution stored in the sample vessel;
• a solution component sensor means having a sensor forming portion formed integrally with an inner portion of the sample suction nozzle means to be inserted into the sample vessel, said solution component sensor means including an output portion for outputting signals, the integral structure of said sample suction nozzle means and said solution component sensor means having a size which fits into a sample vessel along with the elongated front end portion;
• a water-resistant insulation layer formed outside said solution component sensor means for substantially covering the sensor forming portion including the output portion;
• and
• a reference electrode means disposed inside the sample suction nozzle means in communication with said channel at a portion downstream from the solution component sensor means with respect to the flow of the sample in a sample sucking direction.
