Heraeus 1-element 3QAY/Nb (3QAYNb) Hollow Cathode Lamp, Niobium Nb, 37 mm Standard, 2pin - 80014140

Heraeus 1-element 3QAY/Nb (3QAYNb) Hollow Cathode Lamp, Niobium Nb, 37mm Standard, 2pin

Hollow cathode lamps (HCL) are discharge lamps designed for use in Atomic Absorption (AA) instruments. They consist of a cathode made from the element of interest, an anode and an inert filler gas contained in a glass envelope. Noblelight offers the widest selection of single- and multielement coded / non-coded in low and high-current, 37 mm and 50 mm lamps in the industry.

Noblelight hollow cathode lamps are available both for OEMs and as a replacement lamp by discerning users the world over. The range includes standard lamps and data-coded versions for PerkinElmer and ThermoFisher atomic absorption spectrometers.

• Customary diameters 1 ½" and 2"
• Low-current and high-current versions
• Standard and encoded lamps
• Available for OEMs and end users
• Long life due to higher gas volume
• Clear signals and low distortion due to special cathode technology
• Can be used for almost any AA instrument

Single-Element Lamps

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 37 mm Lamps

37 mm hollow cathode lamps are suitable for most commercial atomic absorption instruments. Standard lamps may also be used in computer controlled spectrophotometers which are designed to take coded lamps as these instruments normally
have the facility to be set up manually.
