    Abstract: A flow controller for use with a liquid chromatography detector. The flow controller includes a flow channel comprising an inlet portion, a control channel portion in communication with the inlet portion, and an outlet portion in communication with said control channel portion. The control channel portion has a cross-sectional area smaller than a cross-sectional area of a drift tube of the liquid chromatography detector for channeling the flow of droplets through the smaller cross-sectional area. The flow controller is shaped and sized to reduce pressure fluctuations and turbulence in the droplet stream of the liquid chromatography detector

    Abstract: Increasing signal to noise ratio in optical spectra obtained by spectrophotometers. An interferometer introduces interference effects into a source light beam. A dual beam configuration splits the source beam having the interference effects into a reference beam and a sample beam. The reference beam interacts with a reference substance and is detected by a reference detector. The sample beam interacts with a sample substance and is detected by a sample detector. An optical spectra of the sample is based on the difference between the detected reference beam and the detected sample beam.

    Abstract: The present invention relates to an automatic chemistry analyzer comprising a reaction disk assembly (1), a sample and reagent disk assembly (2), a probe assembly (3) and a stirring assembly (4). A single probe (5) is used to dispense both the reagent and the sample into the reaction vessels. A pre-heating device disposed in the mechanical arm (6) for supporting the probe (5) pre-heats the reagent sucked into the probe to an appropriate temperature. The reaction vessels are disposable and may be replaced manually. The automatic chemistry analyzer may run single-reagent tests or double-reagent tests. According to the automatic chemistry analyzer of the present invention, the interval between injecting the first reagent of a test and injecting the sample of the same test may be 5.5 operation periods so that the first reagent in the reaction vessel may be maintained at or near an appropriate reaction temperature (37° C.). In a process of running a double-reagent test, the incubation time between injecting the sample and injecting the second reagent is set freely by the operator according to the requirements of the test. The automatic chemistry analyzer and the analyzing method according to the present invention may improve the test correctness.
