应用
Potassium dihydrogen phosphate is used as a food additive, fertilizer (NPK), paint additive, coating additive, adhesive, buffering agent and in optical modulators. It is extensively used in research and analytical laboratories as a buffer in mobile/sample preparations for analysis by high pressure liquid chromatography (HPLC) and also in organic synthesis. MKP, monopotassium phosphate, owing to its non-linear optical properties, is used in optical modulators and for second-harmonic generation (SHG).

咨询

应用
Potassium phosphate is typically used as a component in the preparation of phosphate based buffers. It is convenient stock solution for making phosphate buffers. The pKa of 6.82 (25 C) for phosphate buffers make them a universal buffer for biological applications such as cell culture media, column eluent solutions and reagents used in molecular biology. Specific applications include buffers for protein purification, bioprocessing and diagnostic reagent production. Potassium salts are used where sodium content needs to be minimized or controlled.

备注
Stable under recommended storage conditions. Store in cool, dry conditions in well sealed containers.

一般描述

The accuracy of pH measurement results is directly affected by the buffer reference materials used in calibration. Merck offers you a distinguished range of buffer solutions and substances for the exact calibration of your pH measurement equipment. Using Certipur^® reference materials, you benefit from maximum accuracy, reliability and convenience and avoid costly repeat analyses. For your strictest demands in equipment calibration and monitoring, we provide certified secondary standard buffer solutions and substances offering the highest precision.
Our wide range of pH calibration buffers offers ideal products and packaging for your individual need. All buffer solutions are certified reference materials according to ISO 17034 and qualified in our DIN EN ISO/IEC 17025 accredited laboratory. They are all traceable to NIST (National Institute of Standards and Technology, USA) and PTB (Physical Technical Institute, Germany) primary reference materials. Buffers solutions are offered in plastic bottles, measured at 20 ℃ or 25 ℃.

应用

Potassium dihydrogen phosphate, a monophosphate, is a certified reference buffer solution (CRM) used as a pH buffering agent, typically in combination with dipotassium phosphate.
