.. _extended_mobile_phase_modulator_langmuir_config: Extended Mobile Phase Modulator Langmuir ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ **Group /input/model/unit_XXX/adsorption – ADSORPTION_MODEL = EXTENDED_MOBILE_PHASE_MODULATOR** For information on model equations, refer to :ref:`extended_mobile_phase_modulator_langmuir_model`. ``IS_KINETIC`` Selects kinetic or quasi-stationary adsorption mode: 1 = kinetic, 0 = quasi-stationary. If a single value is given, the mode is set for all bound states. Otherwise, the adsorption mode is set for each bound state separately. =================== ========================= ========================================= **Type:** int **Range:** {0,1} **Length:** 1/NTOTALBND =================== ========================= ========================================= ``EMPM_COMP_MODE`` Determines the mode of each component (:math:`0` denotes the modifier component, :math:`1` is linear binding, :math:`2` is modified Langmuir binding). At most one modifier component is allowed, that is, a modifier is not required. Note that this field has the same name for the externally dependent variant of the model. =================== ============================ ========================================= **Type:** int **Range:** :math:`\{0,1,2\}` **Length:** NCOMP =================== ============================ ========================================= ``EMPM_KA`` Adsorption rate constants **Unit:** :math:`m_{MP}^3~mol^{-1}~s^{-1}` =================== ========================= ========================================= **Type:** double **Range:** :math:`\ge 0` **Length:** NCOMP =================== ========================= ========================================= ``EMPM_KD`` Desorption rate constants **Unit:** :math:`m_{MP}^{3\beta}~mol^{-\beta}~s^{-1}` =================== ========================= ========================================= **Type:** double **Range:** :math:`\ge 0` **Length:** NCOMP =================== ========================= ========================================= ``EMPM_QMAX`` Maximum adsorption capacities **Unit:** :math:`mol~m_{SP}^{-3}` =================== ========================= ========================================= **Type:** double **Range:** :math:`\ge 0` **Length:** NCOMP =================== ========================= ========================================= ``EMPM_BETA`` Parameters describing the ion-exchange characteristics (IEX) **Unit:** :math:`mol~m_{SP}^{-3}` =================== ========================= ========================================= **Type:** double **Range:** :math:`\ge 0` **Length:** NCOMP =================== ========================= ========================================= ``EMPM_GAMMA`` Parameters describing the hydrophobicity (HIC) **Unit:** :math:`m_{MP}^{3} mol^{-1}` =================== ========================= ========================================= **Type:** double **Range:** :math:`\ge 0` **Length:** NCOMP =================== ========================= =========================================
