  • Publication number: 20140318224
    Abstract: A high-pressure constant flow rate pump transfers a solvent from a low-pressure side liquid transfer system even if a difference between mixing ratios is large when solvents are mixed during high-pressure gradient liquid transfer. A pressure detection value from a second pressure sensor and a pressure detection value from a fourth pressure sensor are compared with each other. If the pressure detection value PA1 of the second pressure sensor is equal to or greater than the pressure detection value PA2 of the fourth pressure sensor, a second check valve comes into an opened state and operation is ended. If PA1 is less PA2, leakage determination is implemented. If it is determined that no leakage occurs, the type of the solvent is identified. A compression distance of a second plunger which is determined for each solvent and stored in a memory is added and the first plunger is driven.

  • Patent number: 8871088
    Abstract: The present invention provides a liquid delivery device for liquid chromatographs which, by performing liquid delivery at an accurate flow rate with limited pulsation, gives accurate results of analysis. The present invention, with a view to preventing erroneous operation due to errors in measurements at the time of judgment of completion of compression of liquid, establishes the judgment point before the pressure measured by a cylinder pressure detector agrees with the pressure measured by a discharge pressure detector and also calculates the point of completion of compression. Control in this manner prevents pressure fluctuation. It also calculates for control the point of completion of compression from the history of compression performed previously.

  • Patent number: 8375772
    Abstract: An object of the present invention is to improve the accuracy in analysis repeatability of a liquid chromatography apparatus that feeds different eluent by use of a plurality of pumps and achieves the mixture of eluent. Each of the pumps includes means for notifying an automatic sampler and a higher-level control unit that the specified timing of a liquid feeding cycle is reached. A pump whose liquid feeding cycle is the slowest transmits own information so that analysis is synchronized with a liquid feeding cycle. Moreover, a cycle position of a liquid feeding cycle at the end of analysis is expected, and the analysis time is automatically adjusted so that the wait time until the start of the next analysis becomes the shortest.

  • Publication number: 20120002817
    Abstract: A validity information processing section determines a valid MKB and a valid intermediate key by referring to validity information in a recording medium, and, when an MKB and an intermediate key that are not valid have been rewritten, rewrites the validity information in the recording medium. An MKB processing section reads the valid MKB from the recording medium and performs updating processing on an MKB stored in the key management device, and rewrites the non-valid MKB in the recording medium. An intermediate key processing section reads the valid intermediate key from the recording medium and decrypts and re-encrypts the read intermediate key with an authentication key, and rewrites the non-valid intermediate key into the re-encrypted intermediate key.
