⚙️ Design & Construction — AELAB T8001S Atomic Absorption Spectrometer

The AELAB T8001S employs a Czerny–Turner monochromator for stable dispersion and a multi-slot element lamp turret with automatic rotation. A Pure Titanium atomization chamber resists acid gases; a high-efficiency glass atomizer ensures consistent aerosol formation. The integrated chassis houses the graphite furnace power supply and spectrometer to minimize EMI, while USB3.0 connectivity links the control software for GLP data handling.

🔬 Working Principle / Testing Method

The AELAB T8001S atomic absorption spectrometer measures elemental concentration by atomizing samples in either an air–acetylene flame or an electrothermal graphite furnace. Hollow cathode lamp radiation passes through the atom cloud; absorbance at element-specific wavelengths is measured with automatic wavelength scanning and peak positioning. Quantification uses calibration curves with stored reference conditions, supporting routine photometry and trace analysis under GLP.
