These values apply to mill products Section Exercise care to ast, contact of beryllium-containing solutions with the skin. Samples should be transferred to the spectrophotometer cell just prior to reading.
Cautiously add 35 mL of HNO3 in small increments. Aspirate the appropriate dilution of the reagent blank and the test solutions and record their absorbance readings. Originally published as B — 45 T. Add 20 mL of water and cover with a watch glass. Heavy pieces of metal should also be avoided, as they dissolve too slowly.
Transfer the solution into a 1-L volumetric? Boil to expel the brown fumes, cool, dilute to volume, and mix. Let stand for 10 min. Specimens shall be precipitation heat-treated after cutting and prior to testing.
Should the instrument be equipped for multi-point calibration, make sure that several additional solutions still are analyzed 1b94 ensure that error has not been introduced by the curve-?
Rinse the cathode in a water bath and then dip in two successive baths of ethanol or acetone. Continue as directed in A1. Reserve one portion for measurement of the background color and treat the remaining two in ashm with A1.
