Determination of mercury by atomic-absorption spectrophotometry.
A flameless atomic-absorption system has been developed for the determination of low concentrations of mercury in gaseous, solid and liquid samples of organic and inorganic materials.
متن کاملDetermination of oxalic acid in urine by atomic absorption spectrophotometry.
A method is described for determination of oxalic acid in urine using atomic absorption spectrophotometry. The concentration of urinary oxalic acid is calculated by using the difference between two determinations of calcium: first, the excess of calcium in the supernatant after precipitation as calcium oxalate at pH 5, and second, the total calcium determined at pH less than 1 (endogenous and a...
متن کاملGas-sampling technique for arsenic determination by atomic absorption spectrophotometry.
IN CONVENTIONAL atomic absorption spectrophotometry a solution of the sample is introduced into the flame as an aerosol by means of a nebulizer. However, commercial nebulizers are only about 5 efficient in forming fine droplets suitable for atomization by the flame ( I ) . Furthermore, a solution aspirated at a usual rate of 3-5 ml/min for about 10 sec produces a concentration signal extending ...
متن کاملInvestigation and Determination of Osvix by Gold Nanorods by Spectrophotometry
Background and Aims: Osvix drug is an internal brand of Plavix, which is used to prevent blood coagulation in many heart diseases. The aim of the present study was to measure this drug by gold nanorods in optimum conditions and in real samples. Material and Methods: Gold nanorods were synthesized by the seeded-mediated method. Measurement of Osvix drug by gold nanorods was performed by optimizi...
متن کاملAutomated atomic absorption spectrophotometry. II. The determination of serum magnesium.
The flow system developed for the determination of serum calcium by automated atomic absorption spectrophotometry (AAS) was adapted to the determination of serum magnesium. A comparison of the results of analyses by the present procedure and by an automated fluorometric procedure on identical serum specimens shows excellent agreement. from this laboratory described tile application of automated...
