This procedure is a flame atomic absorption analytical method for sodium and potassium analysis in photoresist. The applicable concentration range is 0.1 to 1 ppm when the sample is diluted one to four. The precision was found to be within 0.1 ppm in a round-robin analysis between four laboratories.
