The utility model relates to a hair curler which comprises a handle, a heating part arranged at the front end of the handle and a heat conduction clamping piece hinged to the side wall of the front end of the handle. The heat-conducting clamping piece and the heating part are arranged side by side; a first electric heating piece is arranged on the heat conduction clamping piece; when the heat conduction clamping piece is folded, the inner side wall and the outer side wall of the heat conduction clamping piece respectively form two heating positions for heating hair, when a user clamps the hair for heating, the hair can be continuously and evenly heated through two heat sources on the inner side and the outer side of each heating position, and the qualitative effect is better and faster.

The application discloses an online detection method for volatile organic compounds based on gas chromatography, and relates to the technical field of gas chromatography analysis.The method is characterized in that: the air to be detected is introduced into a pretreatment pipeline with a built-in spiral condenser for low-temperature enrichment, and then the concentrate is transferred to a resolution chamber through instantaneous heating.Subsequently, the carrier gas carries the resolved material into a gas chromatography separation column, and the components are separated in time sequence through programmed temperature rising.The separated components are detected by a flame ionization detector to generate an original spectrum containing retention time and peak area data.Finally, the original spectrum data are compared with a pre-stored volatile organic compound fingerprint feature library, the target species are matched according to the retention time, and the concentration is directly calculated by using the standard peak area response coefficient in the library to output the detection result.The method improves the enrichment and resolution efficiency through spiral condensation and instantaneous thermal resolution, realizes rapid qualitative and quantitative analysis by using the fingerprint feature library, and improves the automation level and analysis efficiency of online monitoring.
