Deuterium Lamps Deuterium lamps are light sources that utilise the discharge of excited deuterium gas (D2). They emit a continuum of UV light within the wavelength range 185 – 400 nm and discrete lines around this. Therefore they are widely used as an ultraviolet source in analytical equipment, such as UV-Vis spectrophotometers and High Performance Liquid Chromatography (HPLC) instruments. Over the years, Heraeus has developed a lamp technology that meets the ever increasing demands of instrument manufacturers in terms of extremely low detection limits and sensitivity. For such state-of-the-art...

Long Nose Lamp High Stability Lamp High Intensity Lamp High Stability Long-Life Deuterium Lamps Using the improved cathode technology, Heraeus long-life D2 lamps combine a guaranteed lifetime of 2,000 hours with unmatched output stability over their entire life. This sets them apart from many other long-life lamps on the market and makes them the ideal choice for high-end HPLC instruments. High Intensity Lamps Heraeus high intensity deuterium lamps with the new “Enhanced Lifetime Performance (ELP)” technology maintain twice the residual intensity compared to standard D2 lamps at the end of life....

Hollow Cathode Lamps 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. Heraeus offers the widest selection of single- and multi-element coded / non-coded in low and high-current, 37 mm and 50 mm lamps in the industry. They are designed for optimum performance by combining: Good chemical sensitivity High spectral response Stable light output Low noise characteristics Long operating and shelf life Applications Atomic Absorption...

Heraeus 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, Varian and ThermoFisher atomic absorption spectrometers. Lamps for use with Smith-Hieftje background correction can also be offered. Single-Element Lamps The Heraeus catalogue includes 70 single-element lamps in standard 37 mm (1½ 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...

Photoionisation Detector Lamps (PID) Photoionisation detector lamps (PID) are most commonly used in gas chromatography (GC), trace gas monitoring and sample ionisation for mass spectrometry. The PID technique uses a lamp with known photon energies in the vacuum ultraviolet (VUV) region. The output from the lamp is used to photoionise gaseous molecules with ionisation potentials lower than the photon energy emitted. Typical photoionisation detectors measure volatile organic compounds (VOCs) and other gases in concentrations from the ppm to ppb level. Heraeus offers a complete range of PID lamps...

Electrodeless Discharge Lamps (EDL) A high frequency electromagnetic field creates the discharge in an EDL. This removes the need for electrodes, which results in the following advantages over conventional UV lamps: Extended lamp life Elimination of reactions between gas fill and metal electrodes Heraeus is able to offer the following types of EDLs: FiberLight miniature UV-Vis light source Excimer lamp NOx lamp FiberLight Miniature UV-Vis Light Source FiberLight is a UV-Vis light source developed by Heraeus especially for mobile and compact spectroscopy applications. It is a ready-to-use module...

FiberLight features Small size Low power consumption (6 W) Low heat output Instant ignition allowing the possibility of cyclic operation Extended service life of up to 3 years Battery operation for portable instruments FiberLight Replacement Lamps The lamps can be replaced by users at the end of life and are available with quartz windows for 200 –1100 nm and with Suprasil windows for 185 – 1100 nm. Depending on the gas fill, lamps can be either a continuum source (deuterium) or a line source filled with noble gases or mercury. Continuous operation lifetime is 1,000 hours. Excimer Lamp Excimer...

Specialty Light Sources Tungsten Halogen Lamps Tungsten halogen lamps (TH) generate a continuous spectrum between 350 – 3000 nm. The output in the visible range of the spectrum ensures that TH lamps are highly suitable for use in analytical instrumentation. Used in conjunction with deuterium lamps, they provide the wide spectral range required by UV-Vis spectrophotometers. Alone, they are suitable light sources for simple Visible spectrophotometers used in analytical and medical markets. Heraeus TH lamps are designed specifically for use in analytical applications; special quartz envelopes enable...

Sodium Lamp Line Sources The range includes: Mercury Vapour Lamp For applications that require single or multiple line spectra, Heraeus offers low pressure and high pressure mercury lamps with a 253.7 nm line and high pressure mercury lamps with spectral lines between 250 – 580 nm, and from 2 W – 125 W. Applications Photochemical processes Fluorimetry Mercury analysers Fixed wavelength detectors UV aging Black Light Blue Lamp Heraeus manufactures the phosphor-coated TW6W black light blue fluorescent lamp that emits ultra violet radiation in the 300 – 400 nm range. The lamp is fitted with an E27...
