The invention provides a Shenqi Fuzheng injection fingerprint atlas establishing method. The method comprises the steps that an ultra high pressure liquid phase chromatography-mass spectrometer is used to detect Shenqi Fuzheng injection, wherein the chromatography conditions comprise an Agilent Zorbax Eclipse Plus C18 chromatography column of 2.1mm*100mm and 1.8 microns, a mobile phase A which is 0.1% aqueous formic acid and a mobile phase B which is 0.1% formic acid acetonitrile; and gradient elution is used. The elution procedure is as follows: 0 to 0.5min, 95% of mobile phase A, and 5% of mobile phase B; 0.5 to 10min, 95% to 75% of mobile phase A, and 5% to 25% mobile phase B; 10 to 15min, 75% to 45% of mobile phase A, and 25% to 55% of mobile phase B; 15 to 18min, 45% to 0% of mobile phase A, and 55% to 100% of mobile phase B; and 18 to 20min, 0% of mobile phase A, and 100% of mobile phase B.

The invention discloses a protein foam fire extinguishing agent and a preparation method thereof and relates to the technical field of fire extinguishing agents. The protein foam fire extinguishing agent is prepared from the following raw material components in parts by weight: 80-100 parts of thixotropy polysaccharide, 10-20 parts of an F-C surfactant, 100-200 parts of fluoro-protein foam, 5-8 parts of calcium carbonate, 5-10 parts of zeolite, 6-8 parts of bentonite, 10-20 parts of calcium chloride and 8-12 parts of an aluminum oxide clinker. The preparation method comprises the following steps: (1) fully mixing the thixotropy polysaccharide, the F-C surfactant and the fluoro-protein foam at the temperature of 50 to 60 DEG C; (2) respectively grinding the calcium carbonate, the zeolite, the bentonite, the calcium chloride and the aluminum oxide clinker into powder, subsequently screening, or mixing after the screening is ended; (3) mixing the mixture obtained in the step (1) with the mixture obtained in the step (2) at the temperature of 80 to 100 DEG C; (4) filling the mixture into a compression tank. The protein foam fire extinguishing agent disclosed by the invention is low in permeability, long in perdurability, good in stability, high in cohesiveness, good in high freezing resistance, good in fire extinguishment performance, simple in production method and convenient to operate and control.

A data processor for analyzing chromatograms in detail and collecting analysis-associated information necessary for verification of data validity throughout an analysis process. The data processor includes a first data collecting section which collects and records a detector output at every data sampling rate T1 for each sample injection, and a second data collecting section which collects and records the detector output and a monitor output indicating an analysis-associated condition at every data sampling rate T2 over a period from the start to the end of the chromatographic analysis; the data sampling rate T1 is shorter than the data sampling rate T2.
