![]() ![]() Adjust the pH to determine the C value for all columns in the desired pH environment. Select a column to compare from the list below. Step #2 (optional): Select F s Weighting Factors A similarity factor, F s, will be calculated for each of the other columns in the database (below). Additionally, we put in the functions of the HP-16C, the HP-32SII, and the HP-21S. The function set of WP 34S is based on the famous HP-42S RPN Scientific, the most powerful programmable RPN calculator industrially built so far. The F s factor describes the similarity of two columns. wanted and comfortably fitting into your shirt pocket. W C 2.8 is the weighting factor for the difference in charge interactions at pH 2.8 W B is the weighting factor for the difference in hydrogen bond basicity W A is the weighting factor for the difference in hydrogen bond acidity W S * is the weighting factor for the difference in steric interactions W H is the weighting factor for the difference in hydrophobicity S * 1 - S * 2 is the difference between the steric parameters of columns 1 and 2Ī 1 - A 2 is the difference between the hydrogen bond acidity parameters of columns 1 and 2ī 1 - B 2 is the difference between the hydrogen bond basicity parameters of columns 1 and 2Ĭ 2.8 1 - C 2.8 1 is the difference between the charge interaction parameters (at pH 2.8) of columns 1 and 2 H 1 - H 2 is the difference between the hydrophobicity parameters of columns 1 and 2 It is calculated according to the following equation: A large F s factor indicates that two columns are very different.Ī small F s indicates that two columns are very similar. The weighting factors account for the fact that the selectivity of separations are more sensitive to differences in some parameters than others. Default values for the weighting factors are entered automatically below.

WP 31S is the first RPN calculator worldwide featuring a full-fledge UNDO: pressing it will restore the entire calculator status as it was before the last command was executed. Free 15C RPN Scientific Calculator The HP-15C used label addressing with labels 0-9.0-.9 and A-E. This project has created scientific firmware for the HP-20b and HP-30b business calculators. The WP 31S function set, however, is a subset of the one of the WP 34S - except UNDO. ![]() The default values describe the relative importance of each parameter in affecting the selectivity of the separation of an "average" sample. This manual documents the most recent v3.3 of WP 34S, a free software you can use for converting an. REVIEW WP 34S and WP 31S Overview The 2 HP 12C financial calculator Slide Rule vs Calculator Showdown: Decilon u0026 HP-35 How to save and use Library in HP 50g graphing calculator The. For example, the default w H is only 12.5 while that of w C 2.8 is 83, reflecting the fact that, in an "average" sample, a difference in the C 2.8 parameter affects the selectivity of the separation much more than an equivalent difference in the H parameter. In some cases, you may want to change the relative weights. For example, if you are only interested in separating uncharged compounds, a difference in the C 2.8 parameter will have little, if any effect on the separation. Display: The more vertical lines on the display, the easier it is to fit equations and solutions on it.In that case, you may wish to change w C 2.8 to zero in order to get a more relevant measure of the difference between two columns.Check which functions are included in a calculator before buying Applications: Are you an engineer? Surveyor? Medical professional? Math student? All scientific calculators aren’t created equal.By contrast, a student or teacher buying for a classroom may want more affordable options and solar power to save on battery expense Wir haben auch das WP 31S produziert, das vom WP 34S-Quellcode abgeleitet ist.
