![]() ![]() ![]() VWR will support you from the latest life science products to the guaranteed purity of organic building blocks. In principle, it can be measured by flame photometry. Calcium in wet-oxidized samples is determined by AAS. The metal in the lamp is subjected to an electric current, causing it to emit light at a characteristic wavelength specific to the element in the lamp. are used to saturate the atomic transition in the low-density vapour of the lamp. The method involves using hollow cathode lamps containing the metal of interest. Note: Lumina? Hollow Cathode Lamps may also be used with all earlier AA spectrometers that do not have automatic code reading capability by using an appropriate adapter cable.A strong, vibrant research and development group is the lifeblood of all industries. Saturated absorption spectroscopy of calcium in a hollow-cathode lamp. Spectra with sub-Doppler resolution of Cai transitions at 423 (resonant), 610, 612, 616, 645, 657 (intercombination), and 672 nm were obtained by optogalvanic saturation spectroscopy in lamps filled with argon (0.6 and 2. Home>Hollow Cathode Lamps>Single Element Hollow Cathode Lamps for Older PerkinElmer Instruments>Calcium Hollow Cathode Lamp. Calcium has a sharp, intense, analytical emission line at 422.7 nm. ![]() Two (2) Pin Standard Primary Wavelength, 422.7nm Alternative Wavelengths, 239.9nm. A hollow cathode lamp with the cathode made of the material to be analyzed is used. The larger the lamp, the greater the inert gas volume - and the longer the lamp lifetime. We investigated the use of hollow-cathode discharges for high-resolution and high-sensitivity spectroscopy, using atomic calcium. P809 - Hollow Cathode Lamp (HCL) - Calcium Pin Type / Connectivity. For calcium and magnesium calibration, mix 100 mL of standard with 10 mL. To prolong the life of a Lumina? Hollow Cathode Lamp (HCL), we produce lamps with larger internal volume so that a greater supply of fill gas at optimum pressure is available. Turn on instru- ment, apply to the hollow cathode lamp the current suggested. Kinesis Hollow Cathode Lamps, Calcium Carry out quicker start-up times Reduce your operating costs with longer lifetime amp hours Continuous light intensity. (With the exception of Selenium hollow cathode lamps, they have a 2 month warranty due to the volatility of Selenium) Calcium Primary Line: 422. We offer a wide range of single-element and multi-element HCLs, which are ideal for determining most elements by atomic absorption spectroscopy. All lamps have a 6 month warranty against manufacturer defect. Unicam coded 37mm hollow cathode lamp for Calcium and Zinc analysis. Profiles of the 4227 nm calcium line emitted by an electronically modulated hollow cathode lamp (50 duty cycle, 20 mA square wave current) are measured. Please note that multi-element lamps are not designed to be used in a furnace system.Įvery genuine PerkinElmer lamp is designed for use with and tested on our spectrometers to assure compatibility and the highest performance. Multi-Element Lumina? Hollow Cathode Lamp (HCL) for the detection of elemental Calcium (Ca), Magnesium (Mg), and Zinc (Zn).
