Multi-element flame photometerCore principles and technical composition:

　　Multi-element flame photometerUsing emission spectroscopy as the core, metal elements in the sample are atomized by flame excitation and transition to excited states, releasing characteristic spectra of specific wavelengths when returning to the ground state. The instrument achieves quantitative analysis of elements by detecting spectral intensity, and its technical composition includes:

Nebulizer: Convert the sample into micrometer sized droplets to ensure uniform entry into the flame, improving analytical sensitivity and precision.

Burner: Generate high-temperature flames (such as air acetylene flames with a temperature of 2000-3000 ℃) to atomize and excite elements.

Monochromator: Separate the characteristic spectra of target elements and eliminate interference wavelengths.

Photoelectric detection system: converts optical signals into electrical signals and displays concentration values through a readout system (such as a liquid crystal screen).

Technical advantages:

High sensitivity: can detect elements such as potassium (K) and sodium (Na) as low as 0.01ppm.

Fast analysis speed: single detection only takes 8 seconds, short response time, suitable for batch sample analysis.

Multi element synchronous detection: supports simultaneous analysis of potassium, sodium, lithium, calcium, barium and other elements to improve efficiency.

Easy to operate: Built in standard curve and automatic correction function, reducing human error.
