Abstract

The invention relates to the technical field of analyzers, in particular to a sulfur tetrafluoride analyzer comprising a gas chromatograph, a feed tube, a micro sample injection needle, a positioningmechanism, a lifting mechanism and a push block. The feed tube is fixedly communicated with the top of the gas chromatograph. The micro sample injection needle arranged above the feed tube is fixedlyconnected with the push block and is connected to the positioning mechanism; and the positioning mechanism is fixedly connected to the lifting mechanism fixedly connected to the top of the gas chromatograph. According to the invention, the positioning mechanism clamps and locates the push block at the micro sample injection needle rapidly and the lifting mechanism lifts the micro sample injectionneedle stably, so that the micro sample injection needle can be inserted into the feed tube conveniently. The lifting is stable; and the collision damage, caused by shaking, of the micro sample injection needle is avoided. The long-time manual holding is avoided; and the sulfur tetrafluoride product is detected conveniently.

Description

technical field [0001] The invention relates to the technical field of analyzers, in particular to a sulfur tetrafluoride analyzer. Background technique [0002] Sulfur tetrafluoride SF4 is the most effective and widely used selective organic fluorinating agent. It can selectively fluorinate carbonyl and hydroxyl groups. It has an irreplaceable position in the production of fine chemicals, liquid crystal materials and high-end pharmaceutical industries. [0003] The preparation process of sulfur tetrafluoride includes the electrolysis of fluorine, the preparation of iodine pentafluoride, the reaction synthesis of sulfur tetrafluoride, and the separation and capture of sulfur tetrafluoride after the reaction synthesis of sulfur tetrafluoride, the tetrafluoride Sulfur rectification and canning, secondary recovery of iodine pentafluoride and tail gas discharge process, when sulfur tetrafluoride and iodine pentafluoride are reacted to form, it is necessary to use a sulfur tetraf...
