Sentence examples for decomposition of samples from inspiring English sources
The traditional method routinely used in laboratories to analyze mercury (Hg) in honey includes decomposition of samples, cold vapor generation and atomic absorption detection.
The main decomposition of samples occurred between 225 °C and 485 °C at heating rates of 5 40 °C/min; owing to release of 78 82% of total volatiles.
It should also be noted that the decomposition of samples 1 and 2 takes place endo-thermally as opposed to samples 3 and 4, whose decomposition proceeds with the release of the large amount of heat.
Figures 6 and 7 show the curves of the heat release rate dependence on time in the thermal decomposition of samples 3 and 4 in the temperature range of 183.5 245.9 °C.
Figure 10 shows the temperature dependencies of the initial heat release rates (dQ/dt) t=0 in the thermal decomposition of samples 3, 4, 3a and 3b in Arrenius coordinates.
Pt concentrations were measured in serum and urine samples by a sensitive procedure during which high-pressure decomposition of samples is followed by an adsorptive voltammetric measurement.
Open image in new window Fig. 6 Decomposition of sampled signal.
In the decomposition of sample 4 Cl− accelerating action prevails over decreasing the AN decomposition rate in response to H2PO4 −, HPO4 2− and SO4 2− anions and, therefore, the decomposition of this sample occurs with the self-acceleration.
Open image in new window Fig. 8 Dependence of the heat release rate dQ/dt (mW g−1) versus time t (min) in the thermal decomposition of sample 3a Open image in new window Fig. 9 Dependence of the heat release rate dQ/dt (mW g−1) versus time t (min) in the thermal decomposition of sample 3b.
Meanwhile, the slope of the TGA curves in Figure 1 which indicates the rate of the weight loss or interchangeably, rate of thermal decomposition of the samples, is less for the samples containing APP/PER in comparison with the other samples specially those containing MWNTs.
The decomposition activity of samples a and b was the lowest.
