An atomic absolption method was developed for determining silicon in streptomycin without prior separation. The method has a reproducibility of \*2.2 ppm and a detection limit of 5 ppm silicon. Ash-fused and untreated samples were compared, and a deuterium arc background corrector indicated a modera

Detailed procedures were developed for the furnace atomic absorption spectrophotometry (FAAS) determination of aluminum (Al) in serum, urine, cerebrospinal fluid (CSF), and proportionated dialysate. Of particular note were the use of Mg (N0&-6H20 as a matrix modifier and the employment of the standa

## Abstract The determination of silicone in oil was based upon conversion of the oil into waterβsoluble form (Na/KβSoap) in a teflon tube, extraction of the waterβinsoluble, solventβsoluble silicones with petroleum ether, and determination of the silicones in some suitable organic solvent by nonfl
