A set of glass, metal sprayer efficient introduction

In our country by atomic absorption analyze industry famous experts WuTingZhao professor with Chinese patent invention of WNA-X series metal set of glass efficient wu-style sprayer, already is domestic all atomic absorption manufacturers will match key devices, and with all the import atomic absorption form a complete set, for country and enterprise to save a lot of foreign exchange. Wu-style metal set of glass efficient the invention of the sprayer, production, use, make atomic absorption spectrophotometer sensitivity, detection limit, stability have been greatly increase the flame atomic absorption method, reach the highest level.

There are the following three types:

WNA-type 1 regular

WNA-type 2 1-10 mL of ascension in continuous adjustable

WNA-3 type hydrofluoric acid resistance type

Second, the metal sleeve glass sprayer efficient good characteristics:

1, with the high performance and metal glass atomizer sprayer rigidity.

2, use special limited flow into liquid pipe, not easy jam.

3, sensitivity to flame atomic absorption method of the highest level.

4, acid, hydrofluoric acid (except), WNA-3 type hydrofluoric acid resistant.

5, users from the excellent properties, for a long time to come.

Six, can for the domestic and foreign all manufacturers.

Three, metal set of glass structure characteristics: high efficiency mist maker

By coaxial glass tube is inhaled the sprayer, the test solution by compressed air vent pipe, puts it's crash ball cap (different) not interchangeable between sprayer, glass fixed in stainless steel in the cover sprayer, its appearance and each host sprayer adapt to different cities, tube inserted meet special polyethylene limited flow into liquid pipe resistance (organic solvent), or plug-and-socket stainless steel tube--silicon tube-polyethylene limited flow into liquid pipe (not easily fall off, but silicon tube not resistant to organic solvent).

Four, metal set of glass efficient atomizer adjust: installation

1, such as the inner diameter of the bridge can be through the mist maker has set the ball hit the cap sprayer, don't take down the fog room directly into end been transferred to the best state of spray mist maker.

2, such as a sprayer can't go through already set the ball hit the cap, desirable mist sprayer under room end, will take the ball cap has hit the mist maker into a fixed, the set and sprayer hit the ball cap, according to XiaFa transferred to best spray state, will end and returned it to the room on the room and tighten the fog.

Three, the best state regulation: spray water absorption (ascension amount should be more than 4 ml/min), will hit the ball cap is on the vent and back and forth, and observe the rotating out with the state of the air. The best state for:

1) forward spray, each side is symmetrical, Angle bigger;

2) to plane away, each side is symmetrical, adjusted the hit the ball cap after the link rod should be in down + 45 degree Angle within.

Five, the metal sleeve glass efficient working parameters explanation: sprayer

1, the compressed air pressure 0.2 Mpa, under the conditions of use under the air flow meter calibration of measuring flow for 10 or 11 l/min (under the conditions, from export determined). If the air flow meter combination of sprayer in the intake pipe before, this time reading drop for measuring 5.5 l/min. Or so. Host factories are so pick, the reading not used for the calculation of the quantity of computational chemistry (the same situation also can not be used in chemical acetylene flow rate computation). Factories or user of the standard working pressure sprayer change 0.2 MPa, analyzes its performance change. Don't need to use auxiliary fuel gas, the same atomizer help nitrous oxide, also can use method and can provide safety air/laughing gas switch valve, customized 5 cm burner.

2, the sample solution of ascension to determine maximum: copper spectrophotometry shall prevail, about 4-6 ml/min, the ascension quantity can also be applied to other atoms of element of low temperature requirements of high temperature, the atoms of element (such as calcium) should reduce the amount of ascension or too much into flames of fire and aerosol temperature drop, the efficiency, reduce the atoms that determination sensitivity, and reduce the interference of other elements increase, if be measured the concentration of the elements are not particularly low, are not in the best condition, can not replace the current limit determination into liquid pipe.

If use WNA-type 2, the ascension for sprayer is measurable elements, are to be found in ascension, which is the best of the concentration of the larger standard solution (spectrophotometry in 0.3 or so), A continuous increase or decrease of ascension, choose have the largest absorbency of ascension (maximum can not be more than 6 ml/min), far more than WNA-type 1 change into liquid pipe is convenient.

Acetylene flow: with spectrophotometry in 0.3 A of liquid, about mark continuous change acetylene flow rate, choose A maximum absorption flow, note: rich burning flame itself is very big also, especially the absorption of short wave length, the determination has two kinds of different concentrations of measuring standard fluid, absorbency XiangJian (less flame absorption), choose the conditions of the larger difference.

Six, metal set of glass efficient processing and maintenance: sprayer fault

1, be restricted to flow into the liquid tube clogged: usually, plugging in the entrance to remove, or with fingers can reverse the compressed air blow with syringe reverse water injection or.

2, inhaled sample solution will do, tube forming into a string of bubbles, resistance to stop with the fingers, inhaled move into liquid pipe to be sucked, bubble, can normal, also can use syringe attract bubbles.

3 sprayer, tube jam: often plugging in close to the vents, and take hit the ball cap, with compressed air or water injection forming refusing to reverse syringe, never using metal wire tong, otherwise it will damage the mist maker.

4 and the vent air flow channel jam: desirable hit the ball under the cap with backward air or water to rinse, also can use syringe injection flush.

5 and the vent tube or air channels to be organic matter, the accumulation of dust or dry of salt jam: under the ball cap will hit it vent insert heated to a hair smoke of sulphuric acid-heavy chromium acid potassium solution in a few seconds, and then rinse with water cold (note: do not make lotion into the mist maker internal), use for more than six months or find the air flow, also should reduce the processing according to.

6 every time after use, with distilled water spray absorption 2-3 minutes, not with the tap water solution (to prevent clogged dry.

7, work room temperature not less than 10 degrees, otherwise the vent the cooling effect can make ice jams atomizer solution.

8, such as the host of the channel with auxiliary help gas, should help gas shutoff will assist, otherwise does not participate in the spray of fuel gas can make the sensitivity to help reduce gas flow, and too much help not only burn gas, can't even burning flame.

9, all atomizer not interchangeable between hit the ball cap, or reduce the great sensitivity.
