PROBLEM TO BE SOLVED: To more accurately correct the discharge and spot-adhesion amount corresponding to an environmental condition or the like, in order to obtain an accurate spot-adhesion amount, when a liquid is housed in the chip mounted on a suction nozzle and a predetermined amount of the liquid is discharged to be spot-adhered. SOLUTION: This analyzer is equipped with the suction nozzle 2 having the chip 3 mounted thereon, a suction/discharge pump 4 for supplying suction or discharge pressure and a control part 20 for controlling the operation quantity of the pump to perform spot-adhesion of the liquid. Continuous spotting operation for performing discharge and spot-adhesion a plurality of times, using the same chip 3, is made possible. The control part 20 receives the environment detecting signal by means of a temperature sensor 23 and a humidity sensor 24 and performs correction of the discharge operation quantity of the suction/discharge pump 4 at all times of spot-adhesion corresponding to the environment detection signal, on the basis of the average correction characteristics for correcting the fluctuations in discharge quantity with respect to the environmental changes in the saturated state of the vapor pressure in the chip. Also the vapor pressure correcting characteristics are changed corresponding to the material to be spot-adhered. COPYRIGHT: (C)2005,JPO&NCIPI |
