The quartz ball-filled nanocatalysis luminous sensor is provided with a quartz tube (1), wherein both sides of the axial lead of the quartz tube (1) are provided with an injection port (2) and an emptying port (3); a ceramic stick (4) is arranged on the inner middle part of the quartz tube (1); a heater strip (5) is wound outside the ceramic stick (4); a plurality of small quartz balls (6) are filled between the quartz tube (1) and the ceramic stick (4); and the outer surfaces of the small quartz balls (6) are coated with nano materials.
Description
Technical field:
The utility model relates to a kind of nano-material surface-catalyzed luminescent sensor, especially a kind of simple in structure, easy operating, with the air be carrier gas, operating cost low, have good stable and a high quartz ball filled type nano catalytic luminescence sensor of reappearance, detection efficiency and precision.
Background technology:
Existing nano-material surface-catalyzed luminescent sensor be the diameter that will scribble nano material be 4～7mm electric ceramic rod to place diameter be that 12～20mm, length are in the quartz ampoule of 100～150mm, diagonally opposing corner is provided with injection port, drain on quartz ampoule.Corresponding optical filter or grating, the photosignal conversion equipment (near ultraviolet sensitive spectroscopy measurement type Weak-luminescence measuring instrument, photomultiplier etc.) of being provided with outside quartz ampoule with nano material.During measurement, the electric ceramic rod heats nano material, sampling systems such as pneumatic pump enter quartz ampoule with carrier gas from injection port with sample, the nano-material surface of flowing through is discharged from drain, the nano-material surface-catalyzed light that sends is behind optical filter or grating removal parasitic light, become the electric signal that is adapted to data processing units such as microcomputer through the photosignal conversion equipment again, carry out check and analysis.Nano material in the existing nano-material surface-catalyzed luminescent detecting device adopts alundum (Al, zinc paste, iron oxide etc. usually, be used for quantitative test ethanol, trimethylamine etc. and food hormone medicine residue detection etc., have simple in structure, easy operating, (several ten thousand yuan) cheap for manufacturing cost, selectivity and reach advantages such as operating cost is few by force.But, because existing sensor just is coated in nano material electric ceramic rod surface, the surface area of nano-material coating is less relatively, luminescence efficiency is not high, and tested component contacts fully inadequately with nano-material surface, causes detection efficiency, resolution and detection sensitivity etc. not to reach desired level.Particularly when the catalytic luminescence signal of target analytes during near (as ethanol and methyl alcohol, alcohols and ethers etc.), the catalytic luminescence signal on nano catalytic material surface of flowing through is difficult to differentiate, sometimes must change analysis condition could separate signal, not only directly influenced the accuracy of quantitative test, and complex operation, increased time of analyzing and testing.
Summary of the invention:
The utility model is in order to solve the above-mentioned technical matters of existing in prior technology, a kind of simple in structure, easy operating is provided, with the air be carrier gas, operating cost low, have good stable and a high quartz ball filled type nano catalytic luminescence sensor of reappearance, detection efficiency and precision.
Technical solution of the present utility model is: a kind of quartz ball filled type nano catalytic luminescence sensor, it is characterized in that: quartz ampoule is arranged, there are injection port and drain in axial line both sides at quartz ampoule, the middle part is equipped with ceramic rod in quartz ampoule, outside ceramic rod, be wound with heater strip, be filled with a plurality of little quartz balls between described quartz ampoule and the ceramic rod, gravelstone English outer surface of ball scribbles nano material.
The length of described quartz ampoule is 100～150mm, and internal diameter is 12～20mm; Described ceramic rod length is 10～15mm, and diameter is 2～4mm; The diameter of described little quartz ball is 2～5mm.
The utility model is to be filled with a plurality of little quartz ball that outside surface scribbles nano material in quartz ampoule, has increased the surface area of nano-material coating, has further improved luminescence efficiency; The flow path dead volume of sample carrier gas reduces greatly simultaneously, tested component contacts more abundant with nano-material surface, response time on nano material shortens greatly, signal response time is rapid, signal to noise ratio (S/N ratio) strengthens, the signal bands of a spectrum narrow down (similar sharp-pointed chromatogram elution curve), and detection efficiency, resolution and detection sensitivity all improve greatly.The light signal that is detected becomes correlativity with tested component concentrations, can realize sulfuretted hydrogen equal size in the rock gas is carried out fast, accurately detects, and has overcome with gas chromatograph and has analyzed the shortcoming that existing instrument and equipment costs an arm and a leg, analysis time is long.Have (several ten thousand yuan) simple in structure, with low cost, easy operating, selectivity is strong, operating cost is few, have good stable and reappearance, detection efficiency and precision advantages of higher.
