Analytik Jena

The German Jena metal sheathed glass high-efficiency atomizer is used for flame atomic absorption spectrophotometers (mainframe) and has been widely used in various models of atomic absorption spectrophotometers at home and abroad, playing a decisive role in improving the sensitivity and stability of the instrument. No matter what type of atomic absorption is used with this atomizer, it will achieve the highest sensitivity of flame atomic absorption method.

1Metal covered glass high-efficiency atomizerAdvantages:

1. Combining the high performance of glass atomizers with the robustness of metal protective sleeves.

2. The sensitivity has reached the highest level of flame atomic absorption spectrometry.

3. Use a specially designed flow restriction tube to prevent blockage.

4. User free tuning, long-term performance unchanged.

5. High sensitivity: When using an air/acetylene flame to measure 2ug/ml copper, the absorbance * can be better than 0.40A.

6. Good stability: The relative standard deviation (RSD) is less than 0.8%.

IIMetal covered glass high-efficiency atomizerFeatures:

Metal covered glass high-efficiency atomizerIt is an improvement made by Wu Wenjie on the basis of the original WJX-1 glass atomizer, using Wenjie style atomizer technology to enable the WJX-1A high-performance glass atomizer to self spray impurities below 0.4mm, which is not easy to block. The same increase can be controlled within 5-7.5ml, the injection speed is accelerated, and the atomizer performance remains unchanged.

Metal covered glass high-efficiency atomizerEquipped with transparent steel needles, it can be directly penetrated in case of blockage, with unchanged performance.

4Metal covered glass high-efficiency atomizerInstallation

1. If the inner diameter of the atomizer seat can pass through the atomizer with the impact ball cap, the end of the fog chamber can be directly inserted into the atomizer that has been adjusted to spray status without taking off the end of the fog chamber.

2. If the atomizer seat cannot pass through the atomizer with the impact ball cap, take down the end of the fog chamber, insert the atomizer with the impact ball cap removed into the atomizer seat and fix it, put on the impact ball cap, adjust it to the * spray state as follows, then reinstall the end of the fog chamber to the fog chamber and fasten it.

3. Spray adjustment: spray purified 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 fog air flow. The state of the * phase is: spray forward, symmetrical on each side, large included angle, and spread in a plane. After adjustment, the connecting rod that impacts the ball cap should be within 45 degrees from the left to the right from the bottom.

5Metal covered glass high-efficiency atomizerPrecautions

1. If the restricted flow liquid pipe is blocked at the inlet of the restricted flow liquid pipe, it can be gently removed with fingers or blown back with compressed air.

2. When the sample solution is almost completely inhaled, bubbles form inside the capillary tube, and the high resistance can stop the inhalation of the solution. You can gently tap the inlet tube with your fingers to suck away the bubbles.

3. The inner tube of the atomizer is blocked, often near the nozzle. At this time, the impact ball cap can be removed and the blockage can be blown away with compressed air in the opposite direction. Note: Type 1 should never be punctured with metal wire! Otherwise, it will damage the atomizer.

If the 1A atomizer is blocked, a fine wire with a diameter of 0.4mm or less can be used to gently pass through the atomizer to the flow restriction tube.

4. If the inner tube or airflow channel of the nozzle is blocked by dust or dry salts accumulated by organic matter, remove the impact ball cap and insert the nozzle into a sulfuric acid potassium dichromate solution heated to smoke for a few seconds. After cooling, rinse with water. Note: Do not let the washing solution enter the inside of the atomizer! If used for more than six months or if air flow decreases, this method should also be followed.

5. After each use, spray with distilled water for 2-3 minutes (do not use tap water to prevent the solution from drying up and clogging).

6. The studio temperature should not be lower than 10 degrees, otherwise the cooling effect at the nozzle of the atomizer can cause the solution to freeze and block the atomizer.

7. If the main engine has a channel for adding auxiliary fuel gas, the auxiliary fuel gas should be turned off, otherwise the sensitivity of the fuel gas not involved in spray will be too low, and the excessive fuel gas flow will not only consume more fuel gas, but also cannot ignite the flame.

8. All atomizers cannot exchange impact ball caps, otherwise the sensitivity will be greatly reduced.
