Calcium (Ca) Hollow Cathode Lamp

Buck Scientific tests each hollow cathode lamp at our Norwalk, CT manufacturing facility on the new Atomic Absorption spectrometers before shipping them out to customers. All lamps have a 6 month warranty against manufacturer defect.* (With the exception of Selenium hollow cathode lamps, they have a 2 month warranty due to the volatility of Selenium) Calcium Primary Line: 422.7 nm Slit Setting: 7 Buck Scientific sources hollow cathode lamps from a few different vendors, since over time we have learned that some manufactures do different elements better than others. Take our word for it, we have used them all over the last 40 years! Advantages Long life for economical, operator convenience High intensity light output resulting in low signal-to-noise ratio and excellent performance Low operating current to extend lifetime of lamps even further Enhanced sensitivity to produce great results even with difficult samples Quality construction for years of reliable service Compatibility Buck Hollow cathode lamps work with all brand of Atomic absorption spectrometer with the exception of PerkinElmer. High Intensity Our lamps are specially designed to emit high intensity at the recommended operating current, resulting in low Signal-to-Noise ratio and excellent performance. Low Operating Current Our lamps may be operated at only half of the instrument manufacturer's recommended current for sufficient intensity, resulting in long lifetime of the lamps. Category Data Glowing starting voltage: 300 V Radiation stability: 1% over 30 minutes Size: 1.5" lamps Diameter: 38 mm, Length: 160 mm Part #: 4110 Quality Control Utilizes Total Quality Control (TQC) to monitor, control and inspect every single step of the hollow cathode lamp manufacturing process. The materials are carefully selected in our manufacturing to avoid spectral interference from fill gas or impurities in the cathode material.
