High Purity

Ammonium Acetate, HPLC Grade is an inorganic salt used in the preparation of a buffered HPLC mobile phase. It is particularly useful when ionizable analytes are being investigated with reversed phase HPLC (RP-HPLC) to give better peak shape in the chromatogram. With a pKa value of 4.8, this material is a great selection when the required eluent pH is between 3.8 - 5.8 to achieve a particular separation. Spectrum Chemical manufactured HPLC grade salts meet the highest standards for quality and purity.

p-Aminophenylmercuric Acetate (1 per EA )

Ammonium Peroxydisulfate, Purified this highly water soluble oxidizing agent is a salt. It is often used for its oxidizing properties to etch copper on circuit boards. The Purified Grade describes chemicals of good quality where there are no official standards and is normally limited to inorganic chemicals.
