Red and near-infrared inductively coupled plasma emission spectra of fluorine, chlorine, bromine, iodine, and sulfur with a photodiode array detector

Abstract

The domain of a red to near-infrared (near-IR) photodiode array ICP atomic emission spectrograph has been expanded to Include simultaneous detection of fluorine, chlorine, bromine, and sulfur. ICP excited spectra of atomic Iodine are also reported above 650 nm. Thirty-five red-near-IR lines of Iodine were excited from atomized CF3I. A listing of wavelengths and relative Intensities for ICP excitation of F, Cl, Br, I, and S Is presented for the photodiode array detector. This complements an earlier photodiode array listing for C, , N, and O. F, Cl, Br, I, and S can be determined simultaneously with C, , N, and 0 In a single exposure of less than 100 ms.

Characterization of a computerized photodiode array spectrometer for gas chromatography-atomic emission spectrometry

“…There have been efforts to achieve high resolution with a limited number of PDA pixels, by prefiltering the spectrum and overlapping many orders (19,20). Several groups have made use of the emission lines in the near-infrared region, since many lines of interest are close enough together to be analyzed simultaneously with a very large array (21)(22)(23)(24)(25). This advantage is at the expense of a restricted wavelength range, which is located far from some of the most sensitive atomic lines.…”

A 1024×1 linear photodiode array sensor with fast readout speed flexible pixel-level integration time and high stability to UV light exposure

“…As shown in the Fig. 1, spectroscopy system with a PDA sensor of which multiple numbers of PDs is placed in a line measures the dispersed light simultaneously, and it achieves a faster readout speed compared with a single PD-type detector with mechanically moving diffraction grating [1][2][3][4][5][6][7][8] . Recently, a demand for faster readout speed PDA is increasing to shorten the measurement time.…”

Indirect determination of fluoride in aqueous samples by inductively coupled plasma atomic emission spectrometry following precipitation of CeF3

“…An additional obstacle is that the wavelengths of the resonant lines are under 100 nm requiring a sophisticated optical system. Only a few papers are published about fluorine determination in gaseous samples at the non-resonant line (F I 685.602 nm) by ICP-AES using direct injection via a gas sampling loop or a gas chromatographic apparatus [1][2][3]. The fluorine emission line of 685.602 nm can be detected not only with ICP-AES but also with gas chromatography microwave induced plasma atomic emission spectrometry (MIP-AES) [4,5].…”
