“…These elements are frequent components in fertilizers for agricultural (or biological) areas and are also used as feeding markers in nutrition studies of ruminants. Attestation of diode laser based spectrometers have also proved them good for analyzing air and many inert gases emission, for determining actinides in solution and soil matrices for the analytical determination of actinides and rare earth elements [48], and for detecting toxic elements like Cr(III) and Cr(VI) species in deionized and drinking water samples [49].…”

“…8 Wavelength modulation diode laser flame atomic absorption spectrometry (WM-LAAS) was coupled with liquid chromatography for chromium speciation. 9 The speciation of Cr(III) and Cr(VI) has been done with direct-injection nebulization (DIN) and S-O-V ICP-AES. 10 E-O-V ICP-AES could be also used for the detection of chromium species.…”

Low and high resolution inductively coupled plasma mass spectrometry (ICP-MS) coupled with ion chromatography (IC) has been investigated for speciation of Cr(III) and Cr(VI). In particular, the interference of ArC + formed by the carbon in a sample on the simultaneous determination of Cr(III) and Cr(VI) has been studied. In chemical speciation, this study shows that quadrupole type ICP-MS with low resolution has a limitation of simultaneous determination of chromium species if the sample contains the carbon elements. The interference problems can be solved by high resolution ICP-MS.

“…The coupling of DLAAS with high performance liquid chromatography (HPLC) for speciation of chromium(III) and chromium(VI) was recently reported. − Using a simple setup involving a single-beam configuration and linear processing of the detector output, a detection limit of 1 ng/mL was obtained . An improvement in detection limit to, 30 pg/mL, was obtained by use of a higher power of frequency-doubled laser light, a double-beam configuration, and logarthmic processing of the output of the detector .…”

Methylcyclopentadienyl manganese tricarbonyl (MMT) is a fuel additive that has been marketed for use in unleaded gasoline since December 1995. The widespread use of this additive has been suggested to cause health risks, but limitations in data regarding its degradation products and their toxicity prevent an accurate evaluation. To monitor the organomanganese compounds, it is clearly advantageous to employ low-cost, high-sensitivity, manganese-specific instrumentation to perform speciation. In this work, instrumentation fitting these criteria was obtained by the combination of high-performance liquid chromatography (HPLC) with diode laser atomic absorption spectrometry (DLAAS) and was used to determine MMT, its nonmethylated derivative, cyclopentadienyl manganese tricarbonyl (CMT), and inorganic manganese. DLAAS was shown to be a versatile analytical technique for total Mn determination, with a detection limit of 1 ng/mL and a linear dynamic range (LDR) of almost 5 orders of magnitude. Analytical figures of merit for HPLC-DLAAS included a detection limit of 2 ng(as Mn)/mL, a LDR of 3 orders of magnitude, and an analysis time of three minutes. The organometallic compounds are characterized by rapid photolysis in sunlight, and hence, experiments were performed to evaluate whether normal laboratory lighting is suitable for their determination. Our results showed that normal laboratory protocols may be employed except that the organomanganese compounds should be stored away from light except during sample introduction procedures. The ability of the instrumentation to selectively preconcentrate organomanganese compounds while removing inorganic manganese was demonstrated. Sufficient resolution was obtained to determine a 20-fold excess of CMT compared with MMT. The ability of the system to do practical analysis was demonstrated by the accurate determination of MMT in spiked samples of gasoline, human urine, and tap water. These results demonstrate the suitability of HPLC-DLAAS for the speciation of MMT and its derivatives in industrial, toxicological, and environmental samples.
