Abstract: The present invention provides a method for determining hydrogen sulfide (H2S) by headspace single-drop liquid phase microextraction and intelligent device colorimetry, which comprises: taking a silver-gold core-shell triangular nanosheet (Ag@Au TNS) as a nanodetection probe, in combination with an analysis method of headspace single-drop microextraction (HS-SDME), specifically extracting H2S volatilized from a sample to be detected by the nanodetection probe, and detecting H2S in the extracted sample with the help of the photographing function of an intelligent device and a color picking software. Compared with the prior art, the present invention adopts intelligent device colorimetry, with the limit of detection of about 65 nM and the linear range of 0.1-100 ?M, and the established method can be applied to the determination of H2S in actual samples such as egg white, milk and other opaque samples, and has the advantages of few procedures, simple operation, high detection efficiency and the like.

Abstract: The disclosure is directed to a display apparatus, including: a display configured to display a user interface for presenting an electronic program guide; and a first controller configured to: send a first request including live broadcast information to cause a server to determine replay data according to a first live broadcast program included in the live broadcast information; receive the replay data from the server, and control the electronic program guide to display a second live broadcast program with a visual replay identifier.
