Description

Technical field:

[0001] The invention belongs to the field of chemical analysis testing instruments and equipment, and relates to an instrument mainly used for measuring the content of primary amino groups in proteins (including collagen polypeptides and various amino acids)—a primary amino group measuring instrument. Background technique:

[0002] The methods currently used to measure the content of primary amino groups in proteins include ninhydrin colorimetry, TNBS colorimetry, micellar electrokinetic chromatography, formaldehyde method, Van Slyck method, and gas chromatography. Among them, ninhydrin colorimetry and TNBS colorimetry belong to spectrophotometric methods, and both have instrument errors. In addition, in the ninhydrin colorimetric method, the length of time for heating the color and the depth of the color after color development will cause errors; the TNBS colorimetric method is very specific, mainly reacting with the ε-amino group of lysine, and cannot Qua...
