Q. What type of gas is used in a flame photometer?

Answer

Different fuels can be utilized in flame photometry, with air, oxygen, or nitrous oxide (N2O) often serving as the oxidant. The determination of sodium, potassium, lithium, and calcium ions in bodily fluids is routinely performed using flame photometers in clinical laboratories. When compared with other spectrophotometric techniques, such as atomic absorption or atomic emission, flame photometry has the benefit of being far more cost-effective. Because ionization is only a concern at very high temperatures, it is immune to spectral and ionization interferences. The flame photometer provides speedy and precise differential data for normal and abnormal sodium and potassium levels in clinical analysis.
