Abstract : Equipment and procedures are described which allow the analysis of metals in lubricating oils w/o need for dilution or other sample pretreatment. A sample heater has been added to a modified Babington principle nebulizer. This nebulizer is capable of producing, from undiluted oils, aerosols suitable for introduction into an Inductively Coupled Plasma Atomic Emission Spectrophotometer. Heating the samples immediately prior to nebulization greatly increases the output of aerosol and reduces variations in output due to differences in sample viscosity. The type of organometallic complex used in the preparation of standards is shown to be unimportant if the region of the plasma which is observed is well chosen. (Author)
