Flame Photometer for Measurement of Na, K and Ca in Plant Extracts
The most important ions which naturally occur in plant tissues are sodium, potassium, calcium, magnesium, nitrate, sulphate and phosphate. A sample of 5 g of oven-dried plant material contains on average, 25 mg calcium, 9 mg magnesium, 80 mg potassium and 3 mg sodium. The recommended method for the measurement of calcium is to precipitate the calcium as an oxalate, the precipitate is then dissolved and measurement taken from the resulting solution. Sodium and potassium may be measured directly following an ashing ...

Flame Photometer for Measurement of Calcium in Biological Samples
A number of methods have been reported for the measurement of calcium in biological materials by flame photometry or titration. This method employs trichloroacetic acid (TCA) to precipitate the proteins and has been found to be adequate to extract all of the calcium from tissue samples. Sodium, potassium and phosphate caused no significant interference and calcium concentration in the range of 0 to 2 µg/ml is readily determined. ...
