  • Thermodynamic Quantities for the Ionization Reactions of Buffers
    Thermodynamic Quantities for the Ionization Reactions of Buffers Robert N. Goldberg,a… Nand Kishore,b… and Rebecca M. Lennen Biotechnology Division, National Institute of Standards and Technology, Gaithersburg, Maryland 20899 ͑Received 21 June 2001; accepted 16 September 2001; published 24 April 2002͒ This review contains selected values of thermodynamic quantities for the aqueous ionization reactions of 64 buffers, many of which are used in biological research. Since the aim is to be able to predict values of the ionization constant at temperatures not too far from ambient, the thermodynamic quantities which are tabulated are the pK, standard ⌬ ؠ ⌬ molar Gibbs energy rG , standard molar enthalpy rH°, and standard molar heat ca- ؠ ⌬ pacity change rC p for each of the ionization reactions at the temperature T ϭ298.15 K and the pressure pϭ0.1 MPa. The standard state is the hypothetical ideal solution of unit molality. The chemical name͑s͒ and CAS registry number, structure, empirical formula, and molecular weight are given for each buffer considered herein. The selection of the values of the thermodynamic quantities for each buffer is discussed. © 2002 by the U.S. Secretary of Commerce on behalf of the United States. All rights reserved.

  • Biological Buffers and Ultra Pure Reagents
    Biological Buffers and Ultra Pure Reagents Are MP Buffers in your corner? One Call. One Source. A World of Ultra Pure Biochemicals. www.mpbio.com Theoretical Considerations Since buffers are essential for controlling the pH in many Since, under equilibrium conditions, the rates of dissociation and biological and biochemical reactions, it is important to have a association must be equal, they may be expressed as: basic understanding of how buffers control the hydrogen ion concentration. Although a lengthy, detailed discussion is impractical, + - k1 (HAc) = k2 (H ) (Ac ) some explanation of the buffering phenomena is important. Or Let us begin with a discussion of the equilibrium constant (K) for + - weak acids and bases. Acids and bases which do not completely k1 = (H ) (Ac ) dissociate in solution, but instead exist as an equilibrium mixture of k (HAc) undissociated and dissociated species, are termed weak acids and 2 bases. The most common example of a weak acid is acetic acid. If we now let k1/k2 = Ka , the equilibrium constant, the equilibrium In solution, acetic acid exists as an equilibrium mixture of acetate expression becomes: ions, hydrogen ions, and undissociated acetic acid. The equilibrium between these species may be expressed as follows: + - Ka = (H ) (Ac ) k1 (HAc) + - HAc ⇌ H + Ac which may be rearranged to express the hydrogen ion concentration k2 in terms of the equilibrium constant and the concentrations of undissociated acetic acid and acetate ions as follows: where k1 is the dissociation rate constant of acetic acid to acetate and hydrogen ions and k is the association rate constant of the ion 2 (H+) = K (HAc) species to form acetic acid.

  • Biological Buffers
    AppliCations No.2 Biological Buffers Many biochemical processes are markedly impaired by even small changes in the con centrations of free H+ ions. It is therefore usually necessary to stabilise the H+ concentration in vitro by adding a suitable buffer to the medium, without, however, affecting the functioning of the system under investigation. A buffer keeps the pH of a solution constant by taking up protons that are released during reactions, or by r eleasing protons when they are consumed by reactions. This handout summarizes the most commonly used buffer substances and respec- tive physical and chemical properties. Keywords Practical Tips – Preparing Buffer Solutions chemical properties Recommendations for the setting of the pH value of a buffer and storage conditions usefull pH range 1. Temperature Depending on the buffer substance, its pH may vary with temperature. It is therefore advisable, as far as possible, to set the pH buffer preparation at the working temperature to be used for the investigation. For instance the physiological pH value for most mammalian cells at 37°C is between 7.0 and 7.5. The temperature dependence of a buffer system is expressed as d(pKa)/dT, which describes the change of the pKa at an increase of temperature by 1°C. 2. Titration (i) Generally, the pH value is set using NaOH/KOH or HCl. Slow addition of a strong acid or base whilst stirring vigorously avoids local high concentrations of H+ or OH– ions. If this is not done, the buffer substances may undergo chemical changes that inactivate them or modify them so that they have an inhibitory action (Ellis & Morrison 1982).

Although a lengthy, detailed discussion is impractical, + - k1 (HAc) = k2 (H ) (Ac ) some explanation of the buffering phenomena is important. Or Let us begin with a discussion of the equilibrium constant (K) for + - weak acids and bases. Acids and bases which do not completely k1 = (H ) (Ac ) dissociate in solution, but instead exist as an equilibrium mixture of k (HAc) undissociated and dissociated species, are termed weak acids and 2 bases. The most common example of a weak acid is acetic acid. If we now let k1/k2 = Ka , the equilibrium constant, the equilibrium In solution, acetic acid exists as an equilibrium mixture of acetate expression becomes: ions, hydrogen ions, and undissociated acetic acid. The equilibrium between these species may be expressed as follows: + - Ka = (H ) (Ac ) k1 (HAc) HAc H+ + Ac- ⇌ which may be rearranged to express the hydrogen ion concentration k2 in terms of the equilibrium constant and the concentrations of undissociated acetic acid and acetate ions as follows: where k1 is the dissociation rate constant of acetic acid to acetate and hydrogen ions and k is the association rate constant of the ion 2 (H+) = K (HAc) species to form acetic acid.

  • Separation of Biochemical Buffering Agents Using Multi-Mode Liquid
    Application Note 20977 Note Application Separation of Biochemical Buffering Agents Using Multi-Mode Liquid Chromatography with Charged Aerosol Detection Mark Tracy and Xiaodong Liu, Thermo Fisher Scientific, Sunnyvale, CA, USA Key Words Acclaim Trinity P2, mixed-mode chromatography, Corona Veo charged aerosol detector, Good’s buffers, CAD, AEX, CEX, HILIC Abstract Good’s buffers are a series of zwitterionic buffering agents popularly used in biochemical experiments and HPLC mobile phases. We present analytical conditions using the Thermo Scientific™ Acclaim™ Trinity™ P2 column to separate 22 of these and other common buffer ingredients by simultaneous anion exchange (AEX), cation exchange (CEX), and hydrophilic interaction chromatography (HILIC) with simple isocratic conditions. Since by design these buffer ingredients have low UV absorption, we use the Thermo Scientific™ Dionex™ Corona™ Veo™ charged aerosol detector. Introduction Good’s buffers are a series of zwitterionic buffering agents that feature stable pH control, low biological activity, low UV absorbance, and low metal affinity [1-3]. They are widely used in biological experiments and in HPLC mobile phases. Phosphate and TRIS are two other popular provides ideal selectivity for monovalent and multivalent buffering agents. Sodium chloride is commonly used to ions in highly aqueous conditions, and its hydrophilic adjust the ionic strength of buffers. As such, the need may surface makes it useful for separating hydrophilic, neutral arise to perform quality control testing of buffer species using HILIC-mode conditions. HILIC conditions formulations or residue testing after product purification. also permit the separation of monovalent anions and Zwitterions can be analyzed in their neutral forms by cations by ion exchange.
