Buffer solutions prepared from these are typically utilized in reverse-phase high-performance liquid chromatography (RP-HPLC) when the sample forms acidic (oxonium ions (H\u003csub\u003e3\u003c\/sub\u003eO\u003csup\u003e+\u003c\/sup\u003e)) or basic (hydroxide ions (OH\u003csup\u003e−\u003c\/sup\u003e)) groups. Buffers mitigate the impact of oxonium and hydroxide ions, thus reducing pH fluctuations.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\n\u003c\/div\u003e\n\n\u003c!-- Note --\u003e\n\n\n\u003c!-- Base product name --\u003e\n\n\u003c!-- DetailElements --\u003e\n\n\n\u003c!-- DeliveryText --\u003e\n\n\u003c!-- printCatalogLink --\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"col-xs-12 col-md-6\" style=\"flex:0 0 55%; max-width:55%; box-sizing:border-box; margin:10px 0; margin-left:-3%; \"\u003e\n\u003cdiv class=\"product-classifications\"\u003e\n\u003cdiv class=\"headline\" style=\"font-weight:bold; font-size:1.2em; margin-bottom:10px;\"\u003eTechnical Information\u003c\/div\u003e\n\u003ctable class=\"table\" style=\"; table-layout:fixed; word-break:normal; overflow-wrap:break-word; width:100%;\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd class=\"attrib\" style=\"padding:8px 6px; vertical-align:top; box-sizing:border-box; font-weight:bold; font-size:1em; white-space:normal; overflow-wrap:break-word; hyphens:auto; word-break:normal; \"\u003eStorage under inert gas\u003c\/td\u003e\n\u003ctd style=\"padding:8px 6px; vertical-align:top; box-sizing:border-box; font-size:0.92em; white-space:normal; word-break:normal; overflow-wrap:break-word; hyphens:auto; \"\u003e\n\t\t\t\t\t\t\t\t\trecommended \u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\u003cdiv style=\"margin-top:1.5rem;\"\u003e\n  \u003ca href=\"https:\/\/www.carlroth.com\/medias\/SPEZ-2573-EN.pdf?context=bWFzdGVyfHNwZWNpZmljYXRpb25zfDEwNjIzMHxhcHBsaWNhdGlvbi9wZGZ8YUdObEwyZ3pZUzg1TWpVME5qQTBNRGM1TVRNMEwxTlFSVnBmTWpVM00xOUZUaTV3WkdZfDg3MGRjOTBlMjg5Y2UxNjA4NTlhODliZTY3Y2FlNWI0Y2I0OGNmMmE3Y2FhOGQ1Y2NhNWQxODc1Y2NmNTRkMDg\" target=\"_blank\" rel=\"noopener noreferrer\" download style=\"display:inline-flex; align-items:center; gap:.65rem; text-decoration:none; color:#000; font-weight:600; font-size:1rem;\"\u003e\n    \u003csvg style=\"width:1.65rem;height:1.65rem;color:#dc2626;flex-shrink:0;\" viewbox=\"0 0 384 512\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" aria-hidden=\"true\"\u003e\n      \u003cpath d=\"M64 0C28.7 0 0 28.7 0 64V448c0 35.3 28.7 64 64 64H320c35.3 0 64-28.7 64-64V160H256c-17.7 0-32-14.3-32-32V0H64z\" fill=\"#ffffff\" stroke=\"currentColor\" stroke-width=\"32\"\u003e\u003c\/path\u003e\n      \u003cpath d=\"M256 0V128H384L256 0z\" fill=\"currentColor\"\u003e\u003c\/path\u003e\n      \u003ctext x=\"192\" y=\"380\" font-family=\"Arial, Helvetica, sans-serif\" font-size=\"110\" font-weight=\"bold\" fill=\"currentColor\" text-anchor=\"middle\"\u003ePDF\u003c\/text\u003e\n    \u003c\/svg\u003e\n    Technical Documentation (PDF)\n  \u003c\/a\u003e\n\u003c\/div\u003e","brand":"Carl Roth","offers":[{"title":"50 g \/ 1 piece","offer_id":56128398065996,"sku":"2573.1","price":38.6,"currency_code":"EUR","in_stock":true},{"title":"50 g \/ 6+ pieces","offer_id":56128398098764,"sku":"2573.1","price":36.67,"currency_code":"EUR","in_stock":true},{"title":"50 g \/ 24+ pieces","offer_id":56128398131532,"sku":"2573.1","price":34.74,"currency_code":"EUR","in_stock":true},{"title":"250 g \/ 1 piece","offer_id":56128398164300,"sku":"2573.2","price":94.5,"currency_code":"EUR","in_stock":true},{"title":"250 g \/ 6+ pieces","offer_id":56128398197068,"sku":"2573.2","price":89.78,"currency_code":"EUR","in_stock":true},{"title":"250 g \/ 24+ pieces","offer_id":56128398229836,"sku":"2573.2","price":85.05,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/4827\/7068\/files\/1000Wx1000H-HPLC-Salze-Gruppe_4aeefb38-54f6-4f9e-988c-6078090d00e7.jpg?v=1766414049","url":"https:\/\/www.luminixhealth.com\/en-de\/products\/di-potassium-hydrogen-phosphate-2573","provider":"Luminix Health","version":"1.0","type":"link"}
