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.\u003c\/p\u003e","brand":"Spectrum Chemical","offers":[{"title":"Default Title","offer_id":47266361507989,"sku":"A2149-250GM","price":139.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0757\/2327\/6437\/files\/A2149_ZZ613_08_2e77e2d3-5d61-497e-832c-b207063897e4.jpg?v=1776349310","url":"https:\/\/labproinc2.myshopify.com\/products\/spectrum-chemical-ammonium-acetate-hplc-grade-a2149-250gm","provider":"Lab Pro Inc Plus","version":"1.0","type":"link"}
