Method and system for synchronously driving light-dispersing elements, and detector for chromatograph

摘要

Provided is a system for synchronously driving light-dispersing elements capable of synchronously and sequentially changing an excitation-light wavelength and a fluorescence wavelength at high speeds. The system includes: a first light-dispersing unit having a first light-dispersing element and a first pulse motor; a second light-dispersing unit having a second light-dispersing element and a second pulse motor; a memory section for storing light-dispersing element information relating to a change in the wavelength of the monochromatic light and the dynamic characteristics information of the pulse motors; a drive condition setting section for allowing an operator to set synchronous drive conditions; a pulse transmission pattern creator; and a pulse transmitter.

1. A method for synchronously driving light-dispersing elements for driving a first light-dispersing element and a second light-receiving element in a light-dispersing including:
a first light-dispersing unit having the first light-dispersing element and a first pulse motor for driving the first light-dispersing element; a second light-dispersing unit having the second light-dispersing element and a second pulse motor for driving the second light-dispersing element; and a pulse transmitter for transmitting a first pulse number of pulses to the first pulse motor and a second pulse number of pulses to the second pulse motor, wherein the first pulse number of pulses is necessary for sequentially changing, at predetermined intervals, a wavelength of monochromatic light produced by the first light-dispersing device, and wherein the second pulse number of pulses is necessary for sequentially changing, at predetermined intervals, a wavelength of monochromatic light produced by the second light-dispersing device, and the method comprising the steps of: determining a transmission rate of the first pulse number of pulses based on a pulse rate within a start region, a stop region, or a slew range of the first pulse motor; calculating a first pulse transmission time from the first pulse number of pulses and the transmission rate of the first pulse number of pulses; and transmitting the second pulse number of pulses to the second pulse motor within the first pulse transmission time.
