LECO AMA254 Mercury Analyzer with AS254 Solid Autoloader

This LECO AMA254 mercury analyzer with the AS254 automatic solid autoloader comes as seen in photos. Several parts have been replaced by the previous owner and it powers on, but it still requires service. We are selling this unit AS-IS for parts. Computer and software are NOT included.

LECO’s AMA254 advanced mercury analyzer is specifically designed for fast, safe, and accurate determination of trace amounts of mercury in various materials—including coal, combustion residues, soils, biological samples, and other solid/liquid samples.

The AMA254 technique of direct combustion features a combustion/catalyst tube that decomposes a sample in an oxygen-rich environment and removes interfering elements. A gold amalgamator trap collects all mercury from the evolved gases, and a dual-path length cuvette/spectrophotometer specifically determines mercury over a wide dynamic range.

With method approvals by the EPA and ASTM, the AMA254 offers a fast, cost-effective alternative to conventional CVAAS or ICP. This unique system combusts various matrices without sample pre-treatment or concentration steps - saving valuable time. The instrument requires no hazardous chemicals, providing mercury determination in as little as five minutes.

The LECO AS254 is a 44-position automatic solid autoloader designed for use with the AMA254 Advanced Mercury Analyzer to automate the measurement of mercury in solid samples. It facilitates high-throughput analysis by automatically introducing samples into the analyzer's combustion system.
