Abstract
An inductively coupled plasma (ICP) source used in conjunction with a computerized monochromator to detect trace quantities of various elements was developed. The ICP system uses a sequential slew scanning system and a monochromator that is directly programmable in BASIC computer language. Sample analysis involves the following steps: the appropriate argon reference line is located; data is collected; background corrections are made; a Gaussian fit is applied to the data or the maximum raw data value is used; intensity is converted to concentration by using established calibration curves; and results are displayed on the video screen. The standard deviation for 10 replicate calibrations of 8 elements was within per billion range. The authors conclude that the ICP computer controlled double monochromator offers an effective method of analyzing several trace elements sequentially.
