Results for tag: "Hollow Cathode Lamp"

Hollow Cathode Lamps (HCLs) are a type of laboratory equipment used in atomic absorption spectroscopy. They are used to produce a stable, intense, and monochromatic light source for the purpose of measuring the concentration of elements in a sample. HCLs are typically composed of a sealed glass tube containing a cathode and an anode, with a gas-filled space between them. The cathode is typically made of a metal or alloy, while the anode is typically made of a metal oxide. The gas-filled space is typically filled with a noble gas, such as argon or neon. HCLs are used in a variety of industries, including pharmaceuticals, food and beverage, environmental testing, and petrochemicals. They are also used in research laboratories for the analysis of trace elements. HCLs are typically used in conjunction with an atomic absorption spectrometer, which is used to measure the concentration of elements in a sample. The HCL market is highly competitive, with a number of manufacturers offering a wide range of products. Some of the major players in the market include Agilent Technologies, PerkinElmer, Thermo Fisher Scientific, Shimadzu, and Hitachi High-Technologies. Show Less Read more
