The conversion of Methanol to Olefins (MTO) is fast gaining momentum as an alternative a pproach to the production of light olefins (ethylene and propylene) over conventional meth ods such as naphtha steam and fluid catalytic cracking. Already commercially v iable in Chin a, MTO offers low costs of production by utilizing the abundant supply of methanol feedst ock produced from natural gas and coal. However, catalysts used during the MTO process are susceptible to deactivation by certain impurities in the methan ol feedstock. Major elem ents such as calcium, potassium, magnesium and sodium present in methanol can interfere with catalytic activity during the MTO process. Microwave Plasma Atomic Emission Spectrom etry (MP - AES) is becoming increasingly popular as a lowe r cost and safer alternative to Fla me Atomic Absorption Spectrometry (FAAS) for multi - elemental analysis of organic samples. For labs handling organic solvents, the presence of the flame of an FAAS is a concern, req uiring constant supervision.

甲醇制烯烃 (MTO) 作为一种生产低碳烯烃（乙烯和丙烯）的替代方法，呈现出快速增长势头，应用广泛度超过了石脑油蒸气和流化催化裂化等传统方法。由于中国有着充足的天然气和煤制甲醇供应，MTO 通过甲醇生成烯烃的技术路线具有低成本的优势，在中国具有可观的商业化前景。然而，MTO 工艺中使用的催化剂容易受甲醇原料中的某些杂质影响而失活。甲醇中存在的钙、钾、镁和钠等主要元素会影响 MTO 工艺中催化剂的活性。 微波等离子体原子发射光谱 (MP-AES) 作为火焰原子吸收光谱 (FAAS) 的一种成本更低、更安全的替代技术，日益广泛地用于对有机样品进行多元素分析。对使用有机溶剂的实验室而言，需要对 FAAS 中的火焰进行持续监控，这是一件令人头疼的事。 Agilent 4200 MP-AES 使用磁耦合微波能量产生稳定可靠的等离子体，能够直接测量有机溶剂中的主要元素。
