Benefits of consumption burner:
The overall consumption burner has the following benefits.
- There are no losses through condensation of spray; all the material enters the flame.
For this purpose, the emission for a given concentration of analyte within solution is higher than that from a premix flame (along with indirect atomisation).
- No fractionation of the sample takes place in during aspiration. This eliminates errors because of loss of nonvolatile elements.
- Combustible sample example for. Petroleum could be directly aspirated within the flame without any danger of explosion.
Thus, the total consumption burner suffers from the following drawbacks.
- Droplets of widely varying sizes are created during aspiration. Several of the larger droplets are often blown right through the flame without totally evaporating or without pyrolysis of the solute.
- The flame is more strongly cooled through heavier load of the liquid.
- The burner tip could become incrusted along with salts left after evaporation of solvent leading to a modified in the aspiration rate of the solvent.
- The burners are extremely noisy both physically and electronically that lead to poor reproducibility of analytical results.
For the above purpose, the overall consumption burner is not much used except for explosive flames e.g. hydrogen along with other oxidants.
