Graphite Furnace Autosampler PAL, 40 Samples + 10 Standards (CAT#: STEM-AL-9657-ZJF)

The PAL is an autosampler used with a graphite-furnace atomic absorption system. The associated furnace can be programmed to temperatures up to 3000 °C. The autosampler supports automatic addition of up to two chemical modifiers. Multiple injections can be used for sample preconcentration before the measurement cycle. The source states that up to 50 drying and ashing cycles can be applied before the next injection cycle for low-concentration work. The autosampler can prepare calibration with ten standard solutions and automatically analyze forty samples. Listed container volumes are 2 mL for standards and samples, 5 mL for automatically mixed standards, and 10 mL for blanks and chemical modifiers. The system is intended to automate graphite-furnace sample preparation, standardization, modifier addition, and repeated injection steps.
