| titleOfInvention | A kind of pretreatment unit for tungsten disulfide detection |
| abstract | The utility model discloses a kind of pretreatment units for tungsten disulfide detection, including high temperature reaction stove, PULSE HEATING instrument and carbon porous molecular screen；Tungsten disulfide to be detected is placed in graphite crucible, PULSE HEATING is carried out to tungsten disulfide by PULSE HEATING instrument, tungsten disulfide melts sample and becomes gas-phase product；The heating power of PULSE HEATING instrument is controlled by temperature control system, argon gas access tube is passed through argon gas into high temperature reaction stove, the tungsten disulfide of gas phase flows up under the drive of argon gas, across carbon porous molecular screen, carbon porous molecular screen absorbs the element sulphur in tungsten disulfide, gas phase tungsten disulfide enters sulphur removal chamber, and alkali asbestos further absorb element sulphur；Gas phase tungsten disulfide after sulphur removal touches temperature lowering board, makes the reduction of tungsten disulfide temperature become solid-state again by cooling device, tungsten disulfide preferably contacts temperature lowering board after the auxiliary sulphur removal of argon gas access tube, and solid-state tungsten disulfide enters in collecting tank. |
