Abstract:
A system and related method for improved liquid delivery evaluation using a solution containing one or more dyes such that the solution exhibits multiple distinct detectable light absorbance spectral features for calibrating or testing over extended volume or dilution ranges are described. The system includes: a photometric instrument capable of measuring optical absorbance at multiple wavelengths; one or more sample solutions to be dispensed using the liquid delivery system whose performance is being tested or calibrated; and vessels optionally pre-filled, or filled by the user, with diluent solution. The sample solutions contain one or more dyes, chosen so that multiple distinct detectable light absorbance spectral features, such as peaks and/or valleys and/or plateaus of the solution can be distinguished for volume or dilution ranges of interest. The concentrations of the dyes may be chosen so that a large volume delivery device is calibrated using a spectral feature in the solution with a low absorbance per unit pathlength, while a small volume delivery device is calibrated with the same sample solution but using a different spectral feature with a high absorbance per unit pathlength.

Abstract:
The invention discloses a multiple differential volume tube measurement quantity conveying device and its conveying method thereof. The device includes volume tubes, inlet pipes and outlet pipes, in which there are at least two set of volume tubes divided into two groups. The inlet pipe of the volume tube is connected with a main inlet pipe and the outlet pipe of the volume tube is connected with a main outlet pipe. Drive mechanisms to be arranged to drive the volume tubes respectively. The drive mechanism is connected with a controller in complementary manner at the same time. The first step of conveying method is to confirm the conveying state of any referenced volume tube group. The second step is to decide the compensatory conveying volume and the conveying state of the other volume tubes according to the difference between the predetermined conveying volume and the conveying volume of the referenced volume tube groups. This invention improves the technical performance of the measurement and quantitative conveying of a volume tube device, measurement conveying pump and volume tube measurement conveying pump, in which the fluid flows smoothly and continuously.

Abstract:
The invention relates to a method, a device and a test kit for carrying out said method, for determining the volume of a sample of a liquid (A). In order to dye the liquid (A), the method involves preparing a determined concentration of a chromophore indicator in said liquid (A), taking a sample from the liquid (A), measuring the optical absorption of the sample taken and determining the volume of the sample by correlating the measured optical absorption with the concentration of the indicator in said liquid (A). The method is characterised in that ions are used as an indicator for dying the liquid (A), said ions producing the colouring of the sample by complexing with a specific ligand.
Abstract:
The disclosure relates to a system for continuous delivery of a measured flow of liquid to a processing apparatus comprising a reservoir (10) for holding a bulk supply of the liquid and an intermediate vessel (12). A first pump delivers liquid form the intermediate vessel to processing equipment at one rate. A second pump (13) delivers liquid from the reservoir to the intermediate vessel of a second much faster rate. A monitor device (14) continuously monitors the weight of the vessel and controls the first pump accordingly to deliver the required weight of liquid at the required rate to the processing equipment. The monitoring device determines when the weight of liquid in the intermediate vessel has reached a minimum position to initiate operation of the second pump (13) to refill the vessel and a further device terminates operation of the second means when the liquid level in the vessel reaches a maximum position.
