Of these, aqueous 20% sodium hydroxide, Figure 20.4g, usually gives more uniform coloring of the ferrite. Murakami’s and Groesbeck’s reagents have also been used for this purpose. composition and etching principles are listed in Table 2. Light (optical) microscopy (LOM) was used to analyze the microstructure.

In working up this data, the analytical chemists used at least four different approaches to correct the signals: (a) ignoring both the calibration blank, CB, and the reagent blank, RB, which clearly is incorrect; (b) using the calibration blank only; (c) using the reagent blank only; and (d) using both the calibration blank and the reagent blank..

Therefore, it is easy to etch the layered structure in 310S-WM after PWHTs using relatively weak acid (Kalling’s reagent).

The use of the a-methoxy-a-trifluoro- methylphenylacetyl derivative offers the distinct advantage, over other reagents having only proton reso- nances, that determinations of enantiomeric composition based upon fluorine resonances are usually more reliable, REAGENT STORAGE AND STABILITY The unreconstituted reagent is stable in the unopened container until the expiration date on the label when stored at room temperature (below 25 °C). When reconstituted as directed, the reagent is stable for 2 days at room temperature (22–28 °C) and for 14 days in the refrigerator at (2–8 °C). PRECAUTIONS To correct for a constant method error, a blank must account for signals from any reagents and solvents used in the analysis and any bias that results from interactions between the analyte and the sample’s matrix.
