3 Overview

Flame photometer is excited by the flame can emit its characteristic wavelengths of spectral lines of atoms or ions measured in accordance with special elements And Ломакин (Roman gold) formula, the sample K, Na elements quantitative analysis instruments. Mathematical expressions Ломакин formula is. I = acb (1) Where. I --- line intensity; --- A relevant factor and the excitation characteristics of the elements and the excitation light source, at a fixed experimental conditions for the constant; b --- self-absorption coefficient; c --- the concentration of elements in the sample solution. When the sample is low element concentrations, b value close to 1, there are. I = ac (2) Equation (2) is a quantitative basis flame photometric analysis. The main block diagram showing the structure of the instrument as follows.

Monochrome flame photometer system commonly used for spectral interference filter device. Such equipment can be divided in accordance with the reading pointer instrument and digital display instruments, measurement can be divided according to concentration Direct-reading class and the standard curve regression class categories.
