Abstract: A method for determining the flow rate of a liquid flow in a liquid chromatography system. The liquid chromatography system sequentially comprises a fraction valve, a first sensor and a second sensor along a flow path direction, wherein a pipeline between the first sensor and the second sensor has a known inter-sensor pipeline volume. The method comprises: step A: emptying a pipeline between a liquid discharge port of the fraction valve and the first sensor; step B: guiding a liquid flow from a liquid discharge port of the fraction valve to pipelines at positions where the first sensor and the second sensor are located; and step C: determining the flow rate of the liquid flow on the basis of a time difference between a first moment when the first sensor detects a liquid-gas interface where the liquid flow interfaces with a gas and a second moment when the second sensor detects the liquid-gas interface, and an inter-sensor pipeline volume. Further provided is a fraction collector. The accuracy of flow rate measurement and the efficiency of fraction collection can be greatly improved by means of the liquid-gas interface provided by the liquid flow passing through the emptied liquid discharge pipeline.

Abstract: A peak position measurement offset is determined in a two-dimensional optical spectrum. A plurality of peaks are identified that appear in both a spectrum obtained from a reference material at known conditions and a spectrum obtained from a sample of interest. The peak position measurement offset is determined by a comparison of a pattern formed by peak positions of the plurality of identified peaks in the spectrum obtained from the sample of interest against the plurality of identified peaks in the spectrum obtained from the reference material.

Abstract: An uncapping apparatus for a test tube cap includes a drive head having at least two drive head elements. The drive head elements have a first section and a second section located on two opposite sides of a rotary shaft. An elastic element provides a tensioning force to the drive head elements. A switching element is movable between a first position and a second position. In the first position, the second sections are under the tensioning force of the elastic element to cause the first sections to form a first drive head size. In the second position, the switching element acts on the elastic element to change the tensioning force acting on the second sections, so that by rotation of the drive head element, the first sections form a second drive head size. A method for using an uncapping apparatus to open a test tube cap is also described.
