Description
Technical field
The present invention relates to a kind of electrothermal quartz tube atomizers, belong to Instruments in lab component.
Background technology
In analyzing test laboratory, the member of the producible hydride such as the arsenic of trace, antimony, bismuth, selenium, lead, tin, tellurium in sample
Element can carry out analysis measurement with hydride generation-atomic absorption spectrophotometry.Currently marketed quartz ampoule atomizer master
Have：1. flame heated quarty tube atomizer：Quartz ampoule is directly roasted with flame, simple in structure, no electric leakage, electric shock hidden danger,
But temperature is not easy to control, and excessive fire then burns out quartz ampoule, and the then temperature that has not been cooked or heated long enough is too low and not up to atomization requires.2. electrothermal quartz tube
Atomizer：The major advantage of such device is that temperature is easily controllable；Two kinds can be substantially divided into：One is heating wire to be around in T-type
Quartz ampoule, quartz ampoule are tied on sheet metal, and centre is separated by with mica sheet, and sheet metal inserts in flame atomizer burning sealing,
Heating wire is exposed, gives the feeling of terror easily got an electric shock, there are security risks；Another kind is insulated in heating wire outer wrapping cartridge type
Set, the two Ω type sheet metal bandings in outside, this device engage not close, the deficient convenience of operation with flame atomizer, similarly
There are security risks.
Invention content
The present invention partly can keep and develop above-mentioned advantage and can overcome the problems, such as it is above-mentioned exist, provide it is a kind of it is simple in structure,
Safe, practical electrothermal quartz tube atomizer.
Technical solution of the invention is：With the special housing body of ceramics, in-between vertical section is H-type rectangle
Slot type structure, upper capping are surrounded in it electrothermal quartz tube with ceramic cover plate；There are 4 ventholes on cover board, cover board is by two
Upper reed plate is fastened on housing body；There are light path hole, aperture about 10mm in the both ends of slot on the extended line of quartzy nozzle；Slot is just
Face and the back side respectively have 4 ventholes, the wiring of electrothermal quartz tube heating wire to be drawn from the outer hole in front be connected to wiring respectively
On column；Binding post is fixed with screw rod and fragmented 10~15mm of housing body；Power lead is connected to binding post；Built-in two of lower slot
Lower reed, makes to be tightly engaged into flame atomizer.
The electric-heating-wire-heating component of the present invention is installed in the pedestal of ceramic material, completely insulated with the external world, avoids sending out
The directly external radiations heat energy of thermal part, it is no electric leakage, electric shock anxiety；The pedestal of slot type structure engages closely with flame atomizer,
Demolition, installation are convenient, and electrothermal quartz tube dismounting, replacement operation are convenient.Generally speaking, the configuration of the present invention is simple, low cost, safety, property
Can be reliable, it is high-quality.
