WFX-E型原子吸收光谱仪是北京第二光学仪器厂80年代产品,配有中山大学设计的简易电子计算机、MP100型打印机和氘灯背景校正系统,能直读浓度、自动调零和自动打印读数。仪器结构简单,操作方便,适于厂矿使用,目前已在有色金属工业系统应用,对仪器的维护及常见故障的分析与处理有着重要意义。1维护(1)燃烧器的维护。燃烧头使用后必须定期清洗,当吸入含有固体颗粒的溶液或高浓度铜、银、汞试液及有机试液后,应立即进行清洗。对于前者,先用刀片小心刮去燃烧缝内外沉积物,然后将燃烧头浸泡在清洁液中4h以上,再用去离子水冲洗、吹干;对于后者,除清洗燃烧头外,还需从雾化室颈口倒入大量去离子水冲洗雾化室内壁。若吸入了有机试液,要在燃烧器系统内分别吸入原有机试剂、丙酮和1％硝酸溶液各3～5min。
WFX-E atomic absorption spectrometer is the second optical instrument factory in Beijing 80’s products, with a simple design of Sun Yat-sen computer, MP100 printer and deuterium lamp background correction system, direct reading concentration, automatic zero and automatic print reading . The instrument has the advantages of simple structure and convenient operation, and is suitable for factory and mine use. At present, it has been applied in non-ferrous metal industrial systems and is of great significance to the maintenance of instruments and the analysis and treatment of common faults. 1 Maintenance (1) Burner maintenance. The burner must be cleaned regularly after use. Immediately after cleaning the solution containing solid particles or high concentration of copper, silver and mercury test solution and organic test solution, For the former, first with a blade carefully scrape off the sediment inside and outside the combustion seam, and then the combustion head immersed in the cleaning solution more than 4h, then rinsed with deionized water, dry; for the latter, in addition to cleaning the combustion head, Injecting a large amount of deionized water into the neck of the atomization chamber, flush the inner wall of the atomization chamber. If inhaled organic test solution, inhale the original organic reagent, acetone and 1% nitric acid solution respectively in the burner system for 3 ~ 5min.
