50mm PE coded Analyst Hollow Cathode Lamp
The Heraeus hollow cathode lamp product range comprises 70 single-element lamps and more than 120 multi-element lamps of the most varied designs to cover almost all appliances.
The Heraeus catalogue includes 70 single-element lamps in standard 37 mm (1.5 inch) and 50 mm (2 inch) diameters to fit almost any AA instrument. All cathode materials are selected from the highest purity available – usually 99.99 % or better – to ensure high spectral line intensity, stability and low noise with good analytical sensitivity. The window material is selected to achieve the optimum transmission of the primary spectral lines of the cathode element. Borosilicate glass is used for wavelengths over 350 nm, and high quality quartz for shorter wavelengths.
Standard 50 mm Lamps
Perkin Elmer Instruments are unique in requiring hollow cathode lamps with a 2” (50 mm) diameter, and a dedicated electrical connector. Heraeus has developed a full ran- ge of such lamps for direct use in Perkin Elmer instruments utilising the long established features of our standard range but making the necessary processing changes to ensure they are entirely compatible to these instruments.
Data Coded Hollow Cathode Lamps
Heraeus manufacture and supply a complete range of data coded hollow cathode lamps for Varian, Perkin Elmer and Thermo instruments. Data coded hollow cathode lamps incorporate a unique electronic configuration in the base or plug which the instrument recognizes and sets default operating conditions for the routine analysis of that element. The parameters may be overridden by the operator if desired to suit the specific requirements of the analysis. The electronic configuration of the data coding is also specific to each instrument manufacturer and not interchangeable i.e. a Varian coded lamp will not register in a Thermo instrument. Heraeus offers a full range of coded lamps for each manufacturer, the exact range being governed by the software embedded in the instrument.
- Type Of Lamp: Deuterium and Tungsten Halogen
- Parameters: Vary by Element
Hollow cathode lamps are gas discharge devices in which the discharge is highly constrained within the cathode of a specific metal. The resultant output is a unique line spectrum, the most intense of which are suitable for highly specific and sensitive metals analysis. Further derivatives of the fundamental technology extend the applications to include:
- Atomic Absorption Spectroscopy (AAS)
- Atomic Fluorescence Spectroscopy
- Multi wavelength laser tuning
- Laser output stabilisation (optogalvanic effect)
- Multi component analysers
- Environmental analysers
- Medical analysers
- Data coded for use in PerkinElmer AAnalyst Instruments
