Agilent GTA-96 Graphite Tube Atomizer Application Note for Trace Metals in Palm Oil
The document describes a method for monitoring metal contamination in various types of palm oil (crude, refined, degummed, hydrogenated) caused by processing steps like bleaching and deodorization. The analysis utilizes Graphite Furnace Atomic Absorption Spectroscopy (GFAAS), which offers advantages such as requiring small sample quantities and providing greater sensitivity compared to flame methods.
The note outlines specific instrumentation used, including the Agilent SpectrAA-40 spectrophotometer with hollow cathode lamps and an Epson MX-80 printer. It details sample preparation techniques involving dissolution in solvents like DIBK, MIBK, or xylene, and provides optimal furnace program parameters, specifically ashing temperatures (700°C for Iron/Copper, 800°C for Nickel), to ensure accurate results by minimizing background signals while preventing analyte loss.
