  • Publication number: 20130238254
    Abstract: A liquid chromatograph analyzing device, which without an analyst having to set complicated processing conditions before measuring a sample, is able to processes unaffected by fluctuations in room temperature and appearance of ghost peaks. In a liquid chromatograph analyzing device, an automatic sampler, a liquid sending pump, a column oven and a detection device are controlled by a calculation processing device. In addition to chromatograph creation unit, which creates chromatograms of a sample based on input detection signals, the calculation processing device has a correction parameter holding section and correction formula setting unit. The correction formula setting unit provides to the liquid chromatograph analyzing device a functionality for the analyst to set correction formulas for incorporating in the chromatograms created by the chromatograph creation unit changes to environmental conditions such as fluctuations in temperature around the liquid chromatograph analyzing device.

  • Patent number: 8194161
    Abstract: An easy and inexpensive signal readout method is provided for a photodiode array consisting of n pieces of photodiodes whose signals are sequentially read out from the first through nth photodiodes. The method includes a canceling process that is performed one or more times before performing a complete readout operation for sequentially reading out signals from all the photodiodes, and the canceling process includes the steps of sequentially reading out signals of a predetermined number of photodiodes starting from the first photodiode to cancel the signals of these photodiodes and then returning to the readout of the signal of the first photodiode. According to this method, it is possible to easily set an appropriate charging time for each photodiode and yet prevent the photodiodes from becoming saturated.

  • Publication number: 20120111127
    Abstract: An autosampler is provided with a needle, a measuring pump which sucks and discharges liquid through the needle, a movement mechanism for the needle, and an injection port which has a needle sealing surface. A sample liquid is sucked into the needle and then the sample liquid discharged with the tip of the needle pressed to the needle sealing surface. When cleaning the needle sealing surface, a cleaning liquid in within the injection port is sucked and then the cleaning liquid is discharged and sucked into the injection port at a position at which the tip of the needle does not make contact with the needle sealing surface. Alternatively, after the cleaning liquid is discharged into the injection port, the needle may be caused to perform an up and down motion such that the tip of the needle contacts the needle sealing surface and then is lifted.
