摘要:
The invention relates to an adaptation device (21) for adapting an UV- Vis cuvette (17) to perform in-situ spectroanalytical characterization of redox processes using gas species or solutes in a controlled atmosphere, said device being configured so as to fit the open end of a UV-Vis cuvette (17) intended to contain products to be measured during achievement of spectroanalytical measurements. The device comprises a main body (22) configured to form a lid covering the opened end (18) of the cuvette (17), said main body having a first part (23) and a second part (24); a working (13), a counter (14) and a reference (15) electrode with removable parts (132, 142, 52) at the respective ends of three conductors (131, 141, 151) coming from outside and passing through the main body (22); a gas inlet (16) intended to allow introduction of a gas said gas inlet having one aperture (162) directed to the working electrode (13) and second aperture (163) directed to the bottom of the cuvette, a gas outlet (27) intended to let the reactive gas in excess to flow out of the cuvette (17) and an solution inlet tube (28) for titration measurements.
摘要:
A pipette (12) comprises a body portion (14) for aspirating a fluid sample (36) into a pipette tip (16) when attached thereto, wherein the body portion (14) comprises at least one light source (26), or an entry point for light from at least one light source, and at least one detector (48) or at least one exit point for light to a remote detector, the pipette body (14) providing an optical path of light that passes from the light source (26) to the sample (36) in a direction essentially along the longitudinal axis of the pipette tip (16) and an optical path for light from the sample (36) to the detector (48) in a direction essentially along the longitudinal axis of the pipette tip (16). A method, apparatus and kit are also described. The pipette, apparatus, kit and method allow the accurate analysis and quantitative determination of minute amounts of biological samples.
