After a redissolving
in 2 uL 20% acetonitrile, the peptides were eluted onto the target plate with natural drying, added supersaturated CHCA (solvent: 50%ACN0.1%TFA) for nitrogen blasting.
In all composites due to the high solubility of Zn in Al, Al-rich solid solution ([alpha] phase matrix of the composite) formed by redissolving
Zn atoms following the partial Al-Zn phase diagram is presented in Figure 2.
Figure 4 shows the wavelength at maximum absorbance ([[lambda].sub.MAX]) for several QD aliquots that underwent the aforementioned drying and redissolving
To overcome the disadvantage of producing extracts with low concentrations of compounds, evaporating and redissolving
the sample in a small amount of solvents is commonly done.
This usually occurs during the extraction and redissolving
processes required for [sup.31]P NMR, thereby leading to an underestimation of diesters and overestimation of monoesters.
The deposit was dried with electrothermal air drying oven at 40[degrees]C for 2 h, followed by redissolving
with distilled water.
Isolation is guided by the antioxidant activity, initiated by redissolving
the extract by using n-hexene (as nonpolar solvent), ethyl acetate (as semipolar solvent), and residue (as polar fraction).On the basis of the evaluation of the antioxidant, the candidate to be isolated was the ethyl acetate fraction.
In addition, it is worth noting that the formed bubbles during filling can be extremely deformed under high extrusion pressure and/or high shear stress and even disappear completely with the gas in the deformed bubbles redissolving
into polymer melt again.
The pH swing is applied again, first redissolving
the precipitate and then reprecipitating all the metal, increasing the metal concentration each time.
The separated lipids were then prepared for quantitative analysis by redissolving
them in organic solvents.
Methyl esters of the carboxylic acids in the HPLC fractions or synthetic compounds were prepared by redissolving
the dried samples in methanol:1 N HCl (1:3) and heating at 70[degrees]C for 60 min.
Further treatment of the precipitate by redissolving
and ultrafiltering it resulted in a 76% pure a-lactalb.
