Flame photometric determination of electrolytes in tissue and of calcium in serum.
The convenience and accuracy of flame photometric methods for the determination of sodium and potassium in body tissues and fluids suggest the desirability of determining other cations such as calcium and magnesium in the same sample. While reliable procedures for the determination of sodium and potassium have been developed (1, 2), there are apparently no satisfactory flame spectrophotometric ...
متن کاملAn improved flame-photometric method for determining calcium in serum.
Powell (1953) introduced a method for the estimation of serum calcium using the EEL flame photometer, and claimed that it gave results in good agreement with a standard titrimetric procedure. In this laboratory, both these methods were found to give low results when tested against standard sera, prepared by adding known amounts of calcium to serum completely decalcified by treatment with a cati...
متن کاملFlow-injection Post-chemiluminescence Determination of Furazolidone in Animal Feeds
The post-chemiluminescence (PCL) reaction was observed with the mixture solution after completion CL reaction of luminol-H2O2 in present of Furazolidone (FZD). A novel method for the determination of FZD was established by flow-injection PCL. The CL intensity responded linearly to the concentration of FZD in the range 1.0×10 −7 -1.0×10 −5 g mL -1 , with a linear correlation of 0.9949. The detec...
متن کاملInvestigation of Aflatoxins in Imported Animal Feeds in Iran
Background: Aflatoxins (AF’s) are secondary metabolites produced by certain species of fungi on grains and animal feeds. Because of serious impact of AF’s on health, they should be monitored closely in potentially hazardous foods and feeds. Method: In this study, AF’s in imported animal feeds including cereals, corn gluten and meals (pastes derived from the cotton, colza and sunflower seeds) f...
متن کاملThe determination of calcium in biological fluids by flame photometry.
The use of flame photometers has greatly simplified and expedited the estimation of sodium and potassium. Calcium is one of the elements which it is possible to determine by flame photometry, but little advantage has been taken of this fact in biological work for a number of reasons. The concentration of calcium in extracellular fluids is usually less than that of potassium ; a given quantity o...
