Automated Flame Photometric Determination of K2O in Fertilizers

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 ...

Determination of the Total Sulphur Content in Gas Oils with a Flame Photometric Detector

During a study of catalytic hydrodesulphurization of gas oils’ a method was needed not only for the determination of the distribution of sulphur compounds, but also, more importantly, for the determination of total suIphur content. Methods have been published for the determination of the distribution of sulpbur compounds in gas oils using gas chromatography (GC) with a coulometric detector’>3. ...

Simultaneous determination of lithium, sodium and potassium in blood serum by flame photometric flow-injection analysis.

A simultaneous flow-injection analysis (FIA) manifold that could analyse three ions from a single injection was designed, constructed, calibrated and used successfully to analyse Li(+), Na(+) and K(+). This FIA method was 10 times faster than the batch technique. The sample volume required was a fraction of about 1/110 to 1/75 that of the batch technique. The outputs were quite reproducible and...

Determination of total and speciated sulfur content in petrochemical samples using a pulsed flame photometric detector.

The pulsed flame photometric detector (PFPD) has the advantage of being able to measure the concentration of individual sulfur compounds and total sulfur content in a petrochemical sample in a single gas chromatography run. Because it is an equimolar response detector, the PFPD's sulfur response is independent of a compound's molecular structure, and this feature allows quantitation of the tota...
