AMETEK 300-8707 Copper Hollow Cathode Lamp (Cu HCL)

Overview

The AMETEK 300-8707 is a copper hollow cathode lamp built as the light source for atomic absorption spectroscopy (AAS) instruments measuring copper concentration in a sample. As a consumable, application-specific component, it supplies the precise 324.8 nm wavelength light that copper atoms in a flame or graphite furnace absorb, which AAS instruments use to determine copper concentration in the sample being analyzed. Copper is one of the most frequently measured elements in AAS work, so the copper lamp is often the most heavily used lamp in a laboratory’s collection.

As a genuine AMETEK-manufactured single-element lamp, the AMETEK 300-8707 is built to the precise optical and electrical tolerances AAS instrument manufacturers specify for reliable, repeatable analytical results. Seven Star LLC supplies the AMETEK 300-8707 copper hollow cathode lamp to environmental, water-quality, metallurgical, petroleum and food-testing laboratories across Muscat, Sohar, Salalah and the wider GCC.

Operating Principle

Inside the lamp, a copper cathode is bombarded with ions from a low-pressure inert fill gas under an applied current, causing copper atoms to be sputtered from the cathode surface and excited to emit light at copper’s characteristic 324.8 nm wavelength. This narrow, element-specific emission line is what an AAS instrument’s optical path passes through the sample; copper atoms present in the sample absorb a portion of this light in direct proportion to their concentration, letting the instrument calculate a precise copper reading.

The 324.8 nm line is copper’s primary resonance line and gives strong sensitivity for trace work. Because the lamp emits only copper lines and the atomized sample absorbs only at matching wavelengths, the measurement is highly selective even in complex matrices such as digested alloys, oils or food samples. As with any hollow cathode lamp, a short warm-up period lets the emission stabilize before calibration, and the lamp current set in the instrument software is a balance between signal strength and service life.

Engineering Design of the AMETEK 300-8707

The AMETEK 300-8707 uses a quartz window, chosen for its transparency to the 324.8 nm emission wavelength copper analysis requires, and is filled with an inert gas (typically neon or argon) to sustain the sputtering discharge that excites the copper cathode. It follows the standard 1.5-inch (37 mm) lamp diameter and connector format common across AAS instruments designed for this hollow cathode lamp family, simplifying compatibility across common AAS instrument brands.

Lamp output declines gradually over its working life as cathode material is consumed, so heavily used copper lamps are typically replaced more often than lamps for rarely tested elements. To get the most from each lamp, operators should avoid running it above the recommended current, keep the quartz window clean, and allow it to cool before removal. Keeping a sealed spare AMETEK 300-8707 on the shelf ensures that routine copper testing can continue immediately when the in-service lamp reaches the end of its life.

Key Features

The AMETEK 300-8707 provides a dependable copper source for everyday AAS analysis:

• It is a genuine AMETEK single-element copper hollow cathode lamp.
• It emits the copper-specific 324.8 nm primary resonance line.
• A quartz window provides high transmission at the copper analytical wavelength.
• An inert fill gas sustains a stable sputtering discharge at the copper cathode.
• The standard 1.5-inch (37 mm) diameter format suits AAS instruments designed for this lamp family.
• Precision manufacture supports consistent, repeatable analytical results between lamps.
• It serves as a direct replacement wherever the AMETEK 300-8707 is specified.
• Strong single-element emission supports both flame and graphite furnace copper methods.

Industrial Applications

The AMETEK 300-8707 copper hollow cathode lamp is used in environmental testing laboratories, water-quality monitoring facilities and industrial quality-control labs across Muscat, Sohar and Salalah that run atomic absorption spectroscopy for trace-metal analysis, including copper testing in drinking water, wastewater, soil and food and beverage samples. Copper in potable water is often linked to corrosion of copper plumbing, making it a regular parameter for water utilities and building operators.

Beyond environmental work, copper is measured in metallurgical and mining laboratories analyzing ores and alloys, in plating and metal-finishing baths, and in petroleum laboratories testing fuels and lubricating oils, where copper content can indicate bearing or cooler wear. Across these GCC sectors the AMETEK 300-8707 is a routine consumable replacement item, since lamp output gradually degrades with use and must be replaced to maintain analytical accuracy and pass laboratory quality-control checks. Seven Star LLC supplies genuine lamps to laboratories throughout Oman and the GCC, including those in the Sohar and Salalah industrial zones.

Laboratories can monitor the condition of the AMETEK 300-8707 through routine checks of emission energy, baseline noise and calibration sensitivity. A steady decline in energy, noisier baselines or difficulty achieving the expected characteristic concentration are typical signs that the copper lamp should be replaced. Logging lamp hours alongside these checks helps quality managers plan replacements before copper results are affected, which is especially important in accredited laboratories that must demonstrate continuous method performance.
