Spectroscopy is a method used to determine the functional groups in a sample compound that is a solid, liquid, or gas, by exposing a small amount of that sample to various light sources. Spectrophotometers detect and measure the amount of light that a test sample absorbs. Light sources used in spectroscopy are UV/ deuterium lamps, hollow cathode lamps and visible lamps, also known as tungsten halogen bulbs or lamps.

Hollow cathode lamps and tungsten halogen lamps

Hollow cathode lamps, for use in Atomic Absorption (AA) Spectroscopy, laser wavelength calibration (opto-galvanic effect) and for Smith-Heiftje background correction, come in single, two, three, four and six element lamps. These lamps are available in 1½ “ and 2” data coded and non data coded versions for all manufacturers’ instrumentation including Perkin Elmer, Varian, Shimadzu, GBC, Hitachi, Unicam, Thermo Jarrell-Ash, Zeiss and others.

Bulbtronics distributes the largest variety of UV-Vis, ultraviolet and tungsten halogen lamps available in a wide variety of voltages from 4.5 v up to 245 v. Tungsten halogen lamps are commonly referred to as halogen lamps. Halogens are actually high-pressure incandescent lamps that contain halogen gases (iodine or bromine). These gases permit filaments to be operated at higher temperatures where a chemical reaction takes place between tungsten and the halogen gas, producing a bright, white light. Halogen color temperatures range from 3400K for maximum light output to 3200K for film and TV work, to 3000Kor 2900K for extended lamp life. Halogen lamps are available in a range of wattages, voltages and configuration with and without reflectors. Most versions are dimmable. Manufacturers we source from include Osram Sylvania, Philips, GE, Ushio, Thorn, GE, Eiko, EYE (Iwasaki) and more.
