Pu Xi Bei Fen Raleigh East West Analysis Atomic Absorption Hollow Cathode Lamp

Pu Xi Bei Fen Raleigh East West Analysis Atomic Absorption Hollow Cathode LampPu Xi Bei Fen Raleigh East West Analysis Atomic Absorption Hollow Cathode Lamp As an analytical light source, it is mainly used to provide sharp line spectra of the tested element, which can emit characteristic spectral lines of the tested element. Under lower operating current conditions, it can radiate characteristic spectral lines with higher intensity, narrow spectral line width, small self absorption effect, and small radiation solid angle of the lamp. Its usage effect is similar to a point light source, allowing almost all the energy of the characteristic spectral lines radiated by the lamp to pass through the atomizer and enter the monochromator spectroscopic system. Our company adopts * cathode manufacturing technology and vacuum processing technology, and our products have the characteristic radiation spectral line intensity of specific elements, which is high and stable,Low background,High spectral purity, low noise, and high sensitivity,Good stability,Sturdy and reliable, with a long lifespan, it has a * cathode cup system that allows the lamp to reach balance faster, while expanding its internal gas capacity more, enabling each hollow cathode lamp to achieve low efficiency5000 mA.h (milliampere-hour)The service life, even for elemental lamps containing arsenic and mercury. Our company ensures the high quality of every hollow cathode lamp through the use of visualization and photoelectrochemical detection processes. Each lamp undergoes strict quality testing for noise, drift, wavelength accuracy, and energy.

● Product performance parameters
★ Starting voltage: ≤ 360V, low starting voltage (especially when lighting with high frequency), can be applied to various atomic absorption spectrometers (AAS). Generally, the power supply frequency of the AAS lamp is 200Hz, 400Hz or higher, and the lamp needs to be continuously turned on and off hundreds of times per second.
★ High working current: generally between 10-30mA, , The LTL-PE4 and LTL-PE9 hollow cathode lamps are slightly larger.
★ Ultra pure spectral performance: The characteristic radiation spectral line intensity is high and stable, without overlapping interference of emission spectral lines from cathode material impurities or other elements, anode materials, inert gases, etc., and the light source output is continuous and stable.
★ Emission performance: * The cathode ring system ensures uniform and rapid luminescence performance.
★ Noise:<0.3%, signal noise is reduced to a small level.
Background: The radiation background on both sides of the characteristic spectral line is low, and the background intensity near the main analysis line is less than 1% of the analysis intensity.
★ Preheating time:<30 minutes, usually between 5-15 minutes.
★ Stability: ≤+1% - -1%
Copper lamps have a baseline drift of less than 1% within 30 minutes, while other element lamps have a baseline drift of less than 1% within 5 minutes.
★ Lamp body structure: The special design of the base ensures direct connection between the cathode needle and the wiring, with a compact structure, firm and reliable, and easy to use.
★ Lifespan: The gas capacity space is larger than other brand products, and the product has a longer service life. Generally, element lamps are ≥ 5000mA. h, and melting and volatile element lamps are ≥ 3000mA. h, and can be stored for a long time.
