Abstract
Abstract @ A chemical analytical method which comprises continuously measuring chemical changes in chemical analytical instruments of the number k in such a manner that chemical change in one analytical instrument is measured as much as n times, using an analytical instrument-conveying means such as disk having analytical instrument seats of the number k which are arranged endlessly in series at equal spaces and moves as a unit along the series of the seats passing through a sample-supplying position and a measuring position, which is based an arrangement in which the numbers n and k are set to be in mutually prime relation with each other.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
320 words
A chemical analytical method which comprises continuously measuring chemical changes in at least two chemical analytical instruments in such a manner that chemical change in one analytical instrument is measured plural times, using an analytical instrument-conveying means having analytical instrument seats of the number k which are arranged endlessly in series at equal spaces and moves as a unit along the series of the seats passing through a sample-supplying position and a measuring position, which comprises: a first stage of supplying the sample to a chemical analytical instrument placed on the instrument seat at the sample-supplying position, and a second stage of moving the instrument seat carrying the sample-supplied chemical analytical instrument thereon in such a manner that the "n"th instrument seat counted from the instrument seat carrying the sample-suppled chemical analytical instrument reaches the sample-supplying position, in which the number n is the given number of times of measurement on one instrument and the numbers n and k are set to be in mutually prime relation with each other, a third stage of supplying the sample to the chemical analytical instrument on the instrument seat located at the sample-supplying position in the second stage, and a fourth stage of moving the instrument seat carrying the cemical analytical instrument supplied with the sample in the third stage in such a manner that the "n"th instrument seat counted from the instrument seat carrying the chemical analytical instrument supplied with the sample in the third stage reaches the sample-supplying position, a subsequent stage comprising a combination of the third and fourth stages which is performed as much as k-2 times, and stages of measuring chemical changes appearing in the chemical analytical instruments at the measuring position in such a manner that chemical change in one analytical instrument is measured as much as n times, the measuring being performed in parallel with the stages of supplying the sample and moving the instrument seats.
Claim 2
Dependent Claim
320 words
A chemical analytical method which comprises continuously measuring chemical changes in at least two chemical analytical instruments in such a manner that chemical change in one analytical instrument is measured plural times, using an analytical instrument-conveying means having analytical instrument seats of the number k which are arranged endlessly in series at equal spaces and moves as a unit along the series of the seats passing through a sample-supplying position and a measuring position, which comprises: a first stage of supplying the sample to a chemical analytical instrument placed on the instrument seat at the sample-supplying position, and a second stage of moving the instrument seat carrying the sample-supplied chemical analytical instrument thereon in such a manner that the "n"th instrument seat counted from the instrument seat carrying the sample-suppled chemical analytical instrument reaches the sample-supplying position, in which the number n is the given number of times of measurement on one instrument and the numbers n and k are set to be in mutually prime relation with each other, a third stage of supplying the sample to the chemical analytical instrument on the instrument seat located at the sample-supplying position in the second stage, and a fourth stage of moving the instrument seat carrying the cemical analytical instrument supplied with the sample in the third stage in such a manner that the "n"th instrument seat counted from the instrument seat carrying the chemical analytical instrument supplied with the sample in the third stage reaches the sample-supplying position, a subsequent stage comprising a combination of the third and fourth stages which is performed as much as k-2 times, and stages of measuring chemical changes appearing in the chemical analytical instruments at the measuring position in such a manner that chemical change in one analytical instrument is measured as much as n times, the measuring being performed in parallel with the stages of supplying the sample and moving the instrument seats.
