摘要： PURPOSE:To optimize the setting of a base line by recording the output of a measuring instrument as it is and selecting a base line level from measurement record after measurement. CONSTITUTION:When the measurement is started, the measurement output is stored in a memory as it is. In this case, the measurement output is stored in the memory while the output of the measuring instrument which is 0 is regarded as level 0. After the measurement, the measurement data stored in the memory are processed. Namely, the measurement data in the memory 2 are read out and the coordinates of the start and end points of each peak are detected. Then the base line level is set. This base line level is set by a person who takes an analysis by displaying the measurement result. After the setting of this base line level, the base line is subtracted from the measurement data in the memory 2 and the resulting data are displayed on a display device 3; and it is confirmed visually whether or not the base line setting is proper and the peak area is calculated. Consequently, the base line is correctly set and the area of each peak can be found without remeasurement.

摘要： PURPOSE:To obtain the data processor which is upgraded in function by perpendicularly dividing plural peaks and allowing the temporary edition of even the plural peaks in the case of edition of the overlapped spots. CONSTITUTION:The chromatogram waveform P to be subjected to data processing is assumed to be displayed. A peak number n=5 is inputted by a key at this time. The beginning point, vertex and end point of the first peak P0 are then assigned by a cursor and the vertexes and end points of the respective peaks up to the final peak P4 are successively assigned. The start point A of the first peak P0 and the end point B of the final peak P4 are connected and a base line q is determined when the above-mentioned assignment ends. A perpendicular (r) is drawn to the base line q from the end points of the respective peak values P0 to P4 and the peak division is executed. The area enclosed by this base line (q) and the perpendicular (r) is calculated.

摘要： PURPOSE:To measure transmitted fluorescence in the state of high S/N by inserting an optical system for changing the incident direction of the exciting light into the optical path of the exciting light and changing the incident direction of the exciting light to a direction diagonal with a microplate so that the exciting light is not made incident to a detector and the transmitted fluorescence is made incident thereto at the time of making fluorescent measurement. CONSTITUTION:The optical system 5 for changing the incident direction of the exciting light 6 makes the exciting light 6 incident perpendicularly to the microplate by deviating the optical system 5 from the optical path of the exciting light 6 at the time of making transmission and absorption measurement. On the other hand, the optical system 5 to change the incident direction of the exciting light 6 is inserted into the optical path of the exciting light 6 at the time of making fluorescent measurement. The incident direction of the exciting light 6 is made into the direction diagonal with the microplate and the exciting light 6 is no longer made incident to the detector 10 by inserting this optical system 5. The fluorescence 24 is released in the direction of the detector 10 as well as against this and, therefore, the fluorescence 24 is made incident to the detector 10 and is received therein. The transmitted fluorescence is measured in the state of the high S/N in this way.

摘要： PURPOSE:To prevent the deterioration of a photomultiplier tube due to the sudden variation in applied voltage, in a slit circular arc part at the beginning of next line scanning by a rotary slit disc, by taking the weighted average of a detected value held at the time of the finish of previous line scanning and the detected value at the circular arc part to supply the same to a dynode feedback circuit. CONSTITUTION:Irradiated light is blocked by the section between points A-B of a rotary slit disc 6. When switches (SW) 24, 34 are opened in a section 8a, the photometric signal voltage and monitor signal voltage at the A-point are respectively held to a sample holding circuits 26, 36 and respective held voltages are supplied to a dynode feedback circuit until reaching the B-point. Succeedingly, when SW 44, 50 are connected to a b-contact side at the B-point, the difference between held voltage Vh and photometric voltage Vs is operated by the differential amplifying circuit 42 of a weighted averaging circuit 40 and multiplied by a constant (t) by an integrating circuit 46. Further, SW 24, 34 are closed between points B-C and SW 44, 50 are connected to an a-contact side to release sample holding. By this method, the dynode feedback circuit also operates smoothly.

摘要： PURPOSE:To obtain an accurate densitogram even when a sample is obliequely developed or a band is inclined or smiled. CONSTITUTION:A two-dimensional data storing part 2 stores absorption data acquired on a two-dimensional plane together with positional information. When a densitogram segmenting straight line on the two-dimensional plane from which the absorption data are acquired is specified, a normal determining part 4 determines a normal direction on each position of the segmenting straight line. An integration part 6 accesses the absorption data from the storing part 2 and integrates the data in the normal direction determined by the determining part 4 over the specified integration width on each position of the specified segmented straight line. Consequently an one-dimensional densitogram can be obtained.

摘要： PURPOSE:To obtain image analysis data and display information replying to a purpose by displaying only effective spot information by referring to a spot table storage part. CONSTITUTION:Image data is stored in an image data storage part 12, and a spot is detected at a spot detecting part 14 based on the image data, and edge information and a spot inside are stored in a spot information storage part 15 at every spot as information with respect to a spot umber, and also, data representing the validity/invalidity of the spot and the spot number are stored in the spot table storage part 16 corresponding to an address number. When the contour of each spot is displayed on a display part 13, the edge information in the spot information storage part 15 and valid/invalid data in the spot table storage part 16 are referred. Then, only the effective spot information is displayed on the screen of the display part 13. When an unrequired spot is desired to erase, the valid/invalid data in the spot table storage part 16 is rewitten by an unrequired spot erasure designation input means 17.

摘要： PURPOSE:To process the detection of the spot of picture data with ability of a personal computer level by discriminating whether a point is on the inside or outside of the spot from curvature and picture data and storing the spot information of each picture element together with information indicating spot numbers. CONSTITUTION:Spot detection is performed by means of a spot detecting section 10 in such a way that the curvature of picture data is compared with a curvature parameter P1 after the data are calculated and the data are then compared with a level parameter P2. Then the inside edge, outside edge, and inside of a spot area detected and stored in a spot information storing section 12 as information related to a spot number. A spot calculating section 16 calculates the area and position of a spot by using the information of the storing section 12 or the volume of the spot by using the picture data of a picture data storing section 4 in addition to the area and position. Therefore, the spot can be detected from the analysis performed by means of a computer of a personal computer class.
