GaCl

Signal registration was accomplished using the standard measurement scheme, consisting of 2 X 50 recordings with an illumination time of 17 s each. 10 g/L Ga as Ga(N03)s dissolved in 2 % v/v HNO3 / HCl was used as sample and deionized water as reference.

Because of the use of the nitrous oxide/acetylene flame the modified measurement scheme with additional tungsten halogen lamp and emission correction was applied. The registration cycle consisted of 4 x 25 recordings with an individual illumination time of 12 s. 

A compilation of the characteristics of the NH bands can be found in Table 7.10. For recording the spectra the modified registration scheme was applied to eliminate the strong emissions coming from the nitrous oxide/acetylene flame. In total, 4 x 50 spectra were recorded with an illumination time of 12 s each. In the case of sample measurements the nitrous oxide/acetylene flame was turned on, while in the case of blank signal registration the flame was turned off. No additional solution was aspirated by the nebulizer to get the pure spectrum of the flame gases.
