Advantages of Burgener Nebulizers



Burgener Nebulizers are pneumatic parallel path nebulizers (Patented). Their parallel path and Teflon® construction allow MAINTENANCE FREE operation. A typical Burgener Nebulizer is installed in the Spectrometer's chamber when it is received, and left there until it dies.

Typical life spans range from 6 months to 3 years.

They rarely salt up from dissolved salts, and rarely plug from undissolved particles. Should an undissolved particle plug the system, it is easy to remove the capillary tubing and replace it with clean tubing, and the nebulizer is operational as before. Slurry capability is only limited to the particle size that the capillary tubing can handle. The standard capillary tubing has a 0.015" ID, so particles as large as 75 microns ( 0.003 ") can be easily handled. For larger particles, wider ID tubing can be used. We have also a standard Teflon® capillary tubing with a 0.020" ID. This allows a safe usage of 100 micron (0.004") particles without plugging. Note that the nebulizer can Not plug. Only the capillary can plug, and it can be replaced easily.

The Burgener Nebulizer is a new, unique, patented design. It works on the basic principal that any body of liquid can be used to produce a fine mist with a gas stream, if they are in close proximity to each other. It is NOT necessary to have a critical alignment of the gas stream and the liquid. This understanding allows us to produce a nebulizer with a very large opening for the liquid path, preventing the common problem of tiny particles in the liquid from plugging the sample path. Our nebulizers actually have the sample path increase in size near the gas stream, so that any plugging occurs in the capillary tubing that delivers the sample to the nebulizer, and not in the nebulizer itself. To clean our nebulizers of a plug, should one ever occur, just replace the capillary tubing leading to the nebulizer.

Our design also allows us to fabricate the nebulizer out of Teflon® (PTFE & FEP). PTFE & FEP are essentially inert to laboratory chemicals, acids and solvents, and are practically non-wetting. This enables the nebulizer to operate with high dissolved solids. The common problem of salts forming around the gas stream does not occur with Teflon. Teflon does not wet and the salts do not form. There can be some salting with very high Sodium (Na) salts. This is a reaction between Na ions with the Fluorine in the Teflon, and can produce an insoluble salt in some instances. This is RARE: less than 1% of our nebulizer customers have reported this occurrence. For most, this still occurs at rates that are very much slower than with glass or sapphire nebulizers. And the salts can usually be washed off with a dilute HF acid wash.
