{"product_id":"spectrum-chemical-ammonium-acetate-hplc-grade-a2149-250gm","title":"Ammonium Acetate, HPLC Grade","description":"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.","brand":"Spectrum Chemical","offers":[{"title":"Default Title","offer_id":46834244550825,"sku":"A2149-250GM","price":139.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0401\/5452\/9953\/files\/A2149_ZZ613_08.jpg?v=1771878786","url":"https:\/\/labproinc.myshopify.com\/products\/spectrum-chemical-ammonium-acetate-hplc-grade-a2149-250gm","provider":"Lab Pro Inc","version":"1.0","type":"link"}
