- Аннотация: Dual-beam thermal lens spectrometry (TLS) is used as a detection system in HPLC. An algorithm for chromatogram handling, which is based on fast Fourier transform, is developed. The algorithm allows a considerable increase (1.5 to 2 orders) in the sensitivity of HPLC-TLS determinations compared with HPLC with conventional spectrophotometric detection. A comparison of the methods for calculating the performance characteristics from peak heights (conventional approach) and peak areas showed that the latter gives more reliable results. The experimental set-up and developed methods were used for determination of Co and Ni in the form of their pre-synthesised chelates with 4-(2-pyridylazo)resorcinol; the limits of detection are 3.10(-8) and 1.10(-7) M, respectively.
