PerkinElmer Nebulizers

PerkinElmer Nebulizers

THE NEBULIZER IS ONE OFTHE MOST IMPORTANT COMPONENTS IN A FLAME AA SPECTROMETER

Sample solutions, with differing physical properties, must be converted into an aerosol of small, similarly-sized droplets. This places great demands on the design of the nebulizer.All PerkinElmer nebulizer assemblies are adjustable for optimized performance and include easily-interchanged capillary assemblies for simple, reduced-cost maintenance. PerkinElmer nebulizers aremanufactured to exacting tolerances to provide maximum sensitivity. Universal, or, "standard" nebulizers are less expensive than the corresponding high-sensitivity nebulizers and provide a lower level of sensitivity. The universal, or, "standard" nebulizers typically provide better precision and reduced "carryover"
interference when used with solutions that contain high dissolved solids content of higher analyte concentrations.

HIGH-SENSITIVITY NEBULIZER WITH PT/IR CAPILLARY

Our high-precision nebulizer maximizes stability and sensitivity even for the toughest matrices. The nebulizer is adjustable so a wide variety of sample matrices-aqueous or organic, acidic or basic, diluted or concentrated-can be analyzed under optimum conditions. This high-sensitivity nebulizer is fabricated with inert plastic materials for maximum performance and corrosion resistance

High-Sensitivity Nebulizer

• Provides maximum sensitivity, precision and freedom from analyticalinterferences

• The high-sensitivity nebulizer with platinum/iridium capillary is for most solutions, but not for precious metal samples containing aqua regia

• High-sensitivity nebulizer with tantalum capillary used for solutions containing aqua regia

Metal Body Corrosion-Resistant Nebulizers

• For all solutions containing hydrofluoric acid or aqua regia

• For all solutions containing high concentrations of dissolved solids

• All internal components in contact with solutions are constructed of plastic to resist corrosion from concentrated acids

• Reduced performance compared with stainless steel or platinum/rhodium nebulizers

Metal Body Platinum Alloy Nebulizers

• Recommended for most concentrated acids containing >5% acid

• Includes a platinum alloy needle assembly and a tantalum venturi

• Provides maximum chemical resistance

• Not suitable for use with aqua regia or hydrofluoric acid

Plastic Body GemTip^TM  Nebulizers

• Corrosion-resistant and can be used to aspirate almost all solutions,even those solutions containing a high percentage of acids

• Designed to obtain optimum sensitivity, detection limits and precision with flame atomic absorption for both air-acetylene and nitrous oxide-acetylene flames

Metal Body Stainless Steel Nebulizers

• For most solutions containing <5% acid, providing exceptional
  performance and durability

• Excellent performance (precision and signal-to-noise ratio)
