Phosphate solutions

Aqueous solutions of sodium dihydrogen-phophate and potassium dihydrogen- phosphate are used for various analyses as liquid chromatography eluents. These products are filtered through 0.2 μm filter, and their absorbance and fluorescent substance content are guaranteed through the test. They can be used as eluents easily and reliably only by diluting with distilled water and deaerating.
