Let be the th reference-filtered sample and be the th filtered sample obtained by one of the proposed filtering techniques.
The first 6 mL fraction of the filtered sample was discarded.
Filtered sample (100 μL) was added to 900 μL of 1 M HCl.
Filtered sample was then measured for constituent sugar concentrations by HPLC using an Agilent 1200 system (Agilent Technologies, Japan).
This portable system employs gas pressure for reagent propulsion and computer controlled miniature solenoid valves for precise injection of multiple reagents into a flowing stream of filtered sample.
The filtered sample solution was centrifuged at 12,000× g for 20 min, and the supernatant was used for the assay.
In the classical case, with a order filter, it is well known that multiplications and additions are required to compute each filtered sample.
In this case, the reference filter order is reduced for, which reduces the number of operations to deliver a filtered sample [6, 11].
A freshly prepared and filtered sample of white porous silicon in PBS solution is composed of nanoclusters with sizes well below 100 nm, as depicted in Figure 7.
The solution was then filtered, and the filtered sample was immersed in 100 g of distilled water and stirred for 1 h.
For many of the experiments prepared in the presence of atmospheric CO2, total dissolved carbonate was measured from a filtered sample using a carbon analyzer with an IR detector (detection limit = 5 × 10-5 molal).
