原子吸收分析油品中的金属元素

Flame atomic absorption spectrophotometry has been used extensively for a number of years to study trace wear metals in used engine oil (1-5). The investigation of trace metals in engine oil has permitted the identification of wearing components before severe failure, without dismantling of the engine. Thus preventive maintenance can be performed as needed and when convenient resulting in considerable cost savings and reduced down time. Spectrometric Oil Analysis Programs (SOAP) have been implemented by the Armed Services, Commercial Airlines, Railways, Tractor Manufacturers and large trucking firms as a diagnostic tool to monitor engine wear.
