AMETEK 300-2070 Cadmium Hollow Cathode Lamp (AAS Cd)

The AMETEK 300-2070 Cadmium Hollow Cathode Lamp is a single-element AAS lamp engineered for stable, high-intensity cadmium emission, enabling accurate trace and process-lab analysis. Designed for routine QA/QC, environmental testing, metallurgy and refining workflows, this Cd HCL delivers fast warm-up, low noise and repeatable absorbance at the cadmium resonance line (commonly 228.8 nm). As a direct consumable for atomic absorption spectrometers, the 300-2070 helps labs maintain uptime and reproducibility while meeting method-validation and compliance requirements.

Key features include:

single-element Cadmium cathode with optimized fill gas for strong line intensity and low self-absorption; robust sealed glass construction for long operating life; stable discharge with typical operating currents used by major AAS platforms; and consistent output for method transfer and routine calibration. Typical specifications for Cd HCLs used in AAS include nominal operating current in the single-digit mA range, warm-up on the order of minutes for baseline stability, and service life measured in the thousands of hours under recommended duty cycles (exact values depend on the host instrument and settings—verify with your instrument manual).

Applications span industrial hygiene and environmental monitoring (Cd in air/particulate digests), mining and smelting labs (feed, concentrate and tailings assays), battery and electronics supply chain QA, plating bath control, and academic research. The lamp supports standard AAS workflows: instrument auto-optimization, wavelength selection near 228.8 nm, background correction, and calibration with certified cadmium standards. For best results, follow the instrument manufacturer’s current/align guidance and schedule routine intensity checks.

Compatibility & notes:

the 300-2070 is intended for AAS instruments that accept AMETEK-format hollow cathode lamps. Pin/bayonet base type, envelope diameter, and alignment collar may vary by platform; check your spectrometer’s lamp bay, pin-out and maximum current to confirm fit. If you are migrating from a different vendor’s Cd lamp, re-optimize current, slit and burner parameters after installation. Always allow sufficient warm-up before analytical runs.

FAQ:

• Which wavelength is used for cadmium? Most AAS methods use the Cd resonance line around 228.8 nm; confirm in your method/instrument cookbook.

• What is the typical operating current? Cadmium HCLs generally run at low single-digit mA; set per your instrument’s optimization routine.

• How long is the warm-up time? Typically several minutes to reach stable emission; verify with your instrument’s stability indicator.

• Is this a multi-element lamp? No—300-2070 is a single-element Cadmium lamp for highest line intensity and specificity.

• Will it fit my AAS? Check your lamp socket/base type and instrument compatibility; share your model with us for confirmation.
