Atomic Absorption Spectrophotometer - AAS Analyzer - 190-900 nm - 3000°C Graphite Furnace

The Master Science Atomic Absorption Spectrophotometer is a PC-controlled AAS for measuring metals in solution by flame absorption and flame emission. A floating optical platform protects the light path from vibration, and the software handles lamp selection, burner position, slit, gas flow, ignition and wavelength peak searching automatically.

An eight-lamp turret preheats all hollow cathode lamps at once, so sequences across several elements run without waiting, and an optional graphite furnace extends detection to very low concentrations.

Key Benefits

• Safer flame operation: the system shuts off gas automatically on power loss, abnormal flame, low pressure or wrong burner.
• Faster multi-element runs: eight lamps are preheated together and switched automatically.
• Steady optical signal: the Master Science Atomic Absorption Spectrophotometer uses a floating optical platform that resists shock and drift.
• Accurate furnace heating: PID control and 3 ms sampling overcome voltage and resistance changes during the temperature program.
• Standard mains power: the graphite furnace runs on ordinary 220 V supply, with no 380 V line required.

Laboratories that also measure organic contaminants often pair AAS with the Master Science gas chromatograph.

Common Laboratory Problems and How This AAS Helps

How the Master Science Atomic Absorption Spectrophotometer helps with common metal analysis issues:

• Waiting for lamps to warm up: all eight lamps preheat together.
• Operator safety with acetylene: automatic gas shut-off reacts to any abnormal condition.
• Signal drift over long runs: the floating optical platform keeps the light path stable.
• Insufficient sensitivity for trace levels: the optional graphite furnace reaches picogram-level detection.
• Manual record keeping: results export to Excel and print directly.
