Description
Technical field
The utility model relates to detecting instrument technical field, particularly relates to a kind of sampling Graphite Furnace Atomic Absorption spectrophotometer argon gas detection alarm device.
Background technology
Atomic absorption spectrophotometer (AAS) is according to the testing tool that be used for carry out metallic element analysis of material ground state atom steam to characteristic radiation absorption, and atomic absorption spectrophotometer (AAS) sensitively reliably can measure trace or trace element.Atomic absorption spectrophotometer (AAS) is generally divided into the atomic absorption spectrophotometer (AAS) of flame atomic absorption spectrophotometer and band graphite furnace, pyrolytic graphite stove is provided with in sampling Graphite Furnace Atomic Absorption spectrophotometer, element is heated atomization in pyrolytic graphite stove, become ground state atom steam, selective absorbing is carried out to the characteristic radiation that hollow cathode lamp is launched, within the scope of finite concentration, its absorption intensity is directly proportional to the content of element tested in test solution.In the timing of use sampling Graphite Furnace Atomic Absorption spectrophotometric, first to pass into argon gas in graphite furnace to replace, argon replaces must completely can not remainingly have air otherwise easily damage graphite furnace, argon gas is passed into when replacing in prior art, the size observation of argon flow amount is inconvenient, be difficult to ensure that argon gas has enough flows to replace completely, have potential risks, therefore require further improvement.
Summary of the invention
For overcoming the deficiencies in the prior art, the utility model provides a kind of sampling Graphite Furnace Atomic Absorption spectrophotometer argon gas detection alarm device that automatically can detect argon flow amount and time, automatic alarm.
The utility model for the technical scheme reaching above-mentioned technical purpose and adopt is: a kind of sampling Graphite Furnace Atomic Absorption spectrophotometer argon gas detection alarm device, it comprises the argon flow amount pick-up unit be arranged in sampling Graphite Furnace Atomic Absorption spectrophotometer argon inlet pipe, a flowmeter and a ventilation detector switch is provided with in described argon flow amount pick-up unit, described flowmeter is vertically installed, the outside of described flowmeter is provided with the detecting sensor that can detect float position in flowmeter, described detecting sensor is located on an adjustment support, described adjustment support is provided with the protective casing of the described detecting sensor of fixing protection, described detecting sensor is connected with a control device with ventilation detector switch, the timer that can detect argon gas duration of ventilation is provided with in described control device, normal run indicator and an acousto-optic flicker alarm, when argon gas passes into the time, to reach normal run indicator after timer sets value bright, reminds operator's argon replaces to complete and just can carry out further work, when sampling Graphite Furnace Atomic Absorption spectrophotometer argon flow amount is less than setting range, argon flow amount pick-up unit can send sound and light alarm, reminds operator to process in time.
Described detecting sensor is photoelectric detection switch.
A flow control valve is provided with before described flowmeter.
The bypass of the other Measuring error in parallel of described flowmeter.
The beneficial effects of the utility model are: adopt said structure; the spectrophotometric argon inlet pipe of existing sampling Graphite Furnace Atomic Absorption is set up an argon flow amount pick-up unit; flowmeter and the detecting sensor that can detect float position in flowmeter is provided with in argon flow amount pick-up unit; detecting sensor connects a control device again; argon flow amount can be detected in time and argon gas passes into the time; the argon replaces time and flow inadequate time can send acousto-optic warning; before guaranteeing testing, argon replaces fully and completely, can not be damaged by available protecting graphite furnace.
