Beijing Hanshi National Patent
Wu's metal sleeve glass high-efficiency atomizer is a product invented by Professor Wu Tingzhao, a renowned expert in China's atomic absorption analysis industry, and has Chinese patents. The "Hanshi" brand Wu's glass high-efficiency atomizer is exclusively produced by Beijing Hanshi Instrument Co., Ltd. It has been matched with all domestic atomic absorption spectrophotometer manufacturers and can be equipped with imported atomic absorption.
The invention of Wu's metal sheathed glass high-efficiency atomizer has greatly improved the sensitivity, detection limit, and stability of atomic absorption spectrophotometers, reaching the highest level of flame atomic absorption spectrometry.


Beijing Hanshi Wu's NebulizerThere are three types of models:
WNA-1 ordinary metal sheathed glass high-efficiency atomizer
WNA-2 type continuous adjustable metal sleeve glass high-efficiency atomizer with a lifting capacity of 1-10mL
WNA-3 type hydrofluoric acid resistant metal sleeve high-efficiency atomizer



1、 Excellent features
1. Combining the high performance of glass atomizers with the robustness of metal atomizers.
2. Use special restriction to flow into the liquid pipe, which is not easy to block.
3. The sensitivity reaches the highest level of flame atomic absorption method.
4. Acid resistant (except hydrofluoric acid), WNA-3 metal sleeve high-efficiency atomizer can withstand hydrofluoric acid.
5. User free tuning, excellent performance remains unchanged for a long time.


2、 Structural featuresdrop
The inner tube of the coaxial glass atomizer sucks in the tested solution, and the outer tube is connected to compressed air. The nozzle is covered with a removable impact ball cap (different metal sleeves are not interchangeable between high-efficiency glass atomizers). The glass atomizer is fixed in a stainless steel protective sleeve, and its shape is adapted to different atomizer bases of various types of hosts. The inner tube is plugged into a specially designed polyethylene flow limiting tube (resistant to organic solvents), or plugged into a stainless steel tube - silicone tube - polyethylene flow limiting tube (not easy to fall off, but silicone tube is not resistant to organic solvents)

3、 Installation and adjustment
1. If the inner diameter of the metal sheathed glass efficient atomizer seat can pass through the atomizer with the impact ball cap, the end of the fog chamber can be directly inserted into the metal sheathed glass efficient atomizer that has been adjusted to the best spray state without taking off the end of the fog chamber.
2. If the metal sheathed glass high-efficiency atomizer seat cannot pass through the atomizer with the impact ball cap, remove the end of the fog chamber, insert the metal sheathed glass high-efficiency atomizer with the impact ball cap removed into the atomizer seat and fix it, put on the impact ball cap, adjust it to the optimal spray state according to the following method, then reinstall the end of the fog chamber to the fog chamber and fasten it.
3. Adjustment of the best spray state: suck and spray water (the lifting amount should be more than 4ml/min), push the impact ball cap against the nozzle and rotate it back and forth, and observe the state of the sprayed air flow with fog The optimal state is:
1) Spray forward, symmetrical on all sides, with a large angle;
2) Spread out in a flat plane, symmetrical on all sides, and after adjustment, the connecting rod of the impact ball cap should be within a downward ± 45 degree angle.
