Range linear dynamic

The linear dynamic range of this method is 0.1 p.gl to 100 J.gl i The method detection limit (MDE) depends on selected operating conditions and a calibration range. It is important to use high purity reagents in all determinations. 

The strengths of ICP-OES are its speed, wide linear dynamic range, low detection limits, and relatively small interference effects. Automated instruments with...

Sawicki (13) used solid-surface fluorescence techniques extensively in the 1960 s for air pollution research. In 1967, Roth (14) reported the RTF of several pharmaceuticals adsorbed on filter paper. Schulman and Walling (15) showed that several organic compounds gave RTF when adsorbed on filter paper. Faynter et al. (16) reported the first detailed analytical data for RTF and gave limits of detection, linear dynamic ranges, and reproducibilities for the compounds.

Helium MIP-MS is also a very sensitive detection system for organotin compounds, such as tetraethyltin (TET), tetrabutyltin (TBT), triethyltin bromide (TET-Br), tripropyltin chloride (TPT-C1), tributyltin chloride (TBT-C1), and others, separated by CGC [213]. Detection limits at sub-pg levels were achieved, and linear dynamic ranges of at least three orders of magnitude were obtained. 

For new analytical techniques to prosper, they must have demonstrated applications to real-world samples, with outstanding figures of merit relative to competing approaches. Table 10.24 opposes the prospects of conventional separation procedures and advanced in situ analyses by the currently most qualifying techniques. Lab-on-a-chip (LOC) devices are unlikely to be robust enough to cope with the moderately complex (i.e. dirty ) matrices that are real-life samples. Industrial chemists need to avoid a lot of work for every analyte and every matrix. Obstacles to solid analysis are relatively poor sensitivities, narrow linear dynamic ranges and unavailability of solid standards. The trend...

Wangfuengkanagul and Chailapakul [9] described the electroanalysis of ( -penicillamine at a boron-doped diamond thin film (BDD) electrode using cyclic voltammetry. The BDD electrode exhibited a well-resolved and irreversible oxidation voltammogram, and provided a linear dynamic range from 0.5 to 10 mM with a detection limit of 25 pM in voltammetric measurement. In addition, penicillamine has been studied by hydrodynamic voltammetry and flow injection analysis with amperometric detection using the BDD electrode. 

Brenner et al. [ 169] applied inductively coupled plasma atomic emission spectrometry to the determination of calcium (and sulfate) in brines. The principal advantage of the technique was that it avoided tedious matrix matching of calibration standards when sulfate was determined indirectly by flame techniques. It also avoided time-consuming sample handling when the samples were processed by the gravimetric method. The detection limit was 70 ig/l and a linear dynamic range of 1 g/1 was obtained for sulfate.

Dan et al. found that Brij-35 also produces an enhancement of the CL intensity of the reaction of fti.v AL[2-(A, -rnclhyl-2 -pyridiniumyl)ethyl]-AL [(trifluoromethyl)sulfonyl]]oxamide with hydrogen peroxide in the presence of some fluorophors [40], To be precise, the CL intensity increased by a factor of 130 for 8-aniline-1-naphthalenesulfonic acid (ANS) and 5.6 forrhodamine B (RH B), compared to the CL intensity in the absence of surfactant. This leads to an increase of 2-3 orders of magnitude in the linear dynamic ranges and a more precise determination of these analytes. However, improvement of the detection...

Up to 30% hydrogen can be added to the carrier gas stream of a helium microwave plasma torch, in the determination of arsenic, bismuth and tin. The argon torch accepts up to 20% hydrogen LOD about 2.5 pg Sn/L, with linear dynamic range over 3 orders of magnitude23.
