  • MEKC
  • During a MEKC separation, analytes distribute themselves between the hydrophobic interior of the micelle and hydrophilic buffer solution as shown in figure 1. (wikipedia.org)
  • capillary
  • Micellar electrokinetic capillary chromatography (MECC) proved to be satisfactory for the separation of triazines, providing high efficiency in short analysis times. (ndsl.kr)
  • A solid-phase extraction method based on an ionexchange retention mechanism has been used for in-line preconcentration of inorganic anions prior to their separation by capillary electrophoresis (CE). (edu.au)
  • A single capillary containing a preconcentration and a separation zone has been used in a commercial CE instrument without instrumental modification. (edu.au)
  • Optimization of the electrolyte concentrations, sample injection times, and back-flushing times allowed the successful separation of sub-ppb levels of inorganic anions using a 100-min injection at 2 bar pressure, introducing over 40 capillary volumes of sample. (edu.au)
  • Under optimal capillary electrophoresis conditions, the separation of the investigated substances was achieved in less than 5 min and single dilution of each sample was employed. (diva-portal.org)
  • occur
  • 2. If the outcome values are perfectly determined by the predictor (e.g., y = 0 when x ≤ 2) then the condition "complete separation" is said to occur. (wikipedia.org)
  • concentration
  • The intent of separation of powers is to prevent the concentration of unchecked power by providing for "checks" and "balances" to avoid autocracy , over-reaching by one branch over another, and the attending efficiency of governing by one actor without need for negotiation and compromise with any other. (wikipedia.org)
  • spouse
  • A trial separation may allow the spouse who wants the divorce to experience some of the feelings of being separated without making a final decision to divorce. (wikipedia.org)
  • often
  • The separation of powers model is often imprecisely and metonymically used interchangeably with the trias politica principle. (wikipedia.org)
  • Cryogenic air separation units (ASUs) are built to provide nitrogen or oxygen and often co-produce argon. (wikipedia.org)
  • Often other methods are applied to make the separation faster and more efficient, such as flocculation, coagulation and suction. (wikipedia.org)
  • In aerodynamics, flow separation can often result in increased drag, particularly pressure drag which is caused by the pressure differential between the front and rear surfaces of the object as it travels through the air. (wikipedia.org)
  • possible
  • Gravity separation is an attractive unit operation as it generally has low capital and operating costs, uses few if any chemicals that might cause environmental concerns and the recent development of new equipment enhances the range of separations possible. (wikipedia.org)
  • For a stereo mix of relatively simple signals it is now possible to make a fairly accurate separation, although some artifacts remain. (wikipedia.org)
  • For this reason much effort and research has gone into the design of aerodynamic and hydrodynamic surfaces which delay flow separation and keep the local flow attached for as long as possible. (wikipedia.org)
  • Nearly
  • While different chemical elements can be purified through chemical processes, isotopes of the same element have nearly identical chemical properties, which makes this type of separation impractical, except for separation of deuterium. (wikipedia.org)
  • commonly
  • The Separation tree was a heritage listed Eucalyptus camaldulensis tree, commonly known as a red river gum, located in the Royal Botanic Gardens Victoria in Melbourne in Victoria. (wikipedia.org)
  • common
  • The most common method for air separation is fractional distillation. (wikipedia.org)
  • Separation logic assertions describe "states" consisting of a store and a heap, roughly corresponding to the state of local (or stack-allocated) variables and dynamically-allocated objects in common programming languages such as C and Java. (wikipedia.org)
  • On the other extreme, separation of fissile plutonium-239 from the common impurity plutonium-240, while desirable in that it would allow the creation of gun-type nuclear weapons from plutonium, is generally agreed to be impractical. (wikipedia.org)
  • process
  • The cryogenic separation process requires a very tight integration of heat exchangers and separation columns to obtain a good efficiency and all the energy for refrigeration is provided by the compression of the air at the inlet of the unit. (wikipedia.org)
  • Isotope separation is the process of concentrating specific isotopes of a chemical element by removing other isotopes. (wikipedia.org)
  • Isotope separation is an important process for both peaceful and military nuclear technology, and therefore the capability that a nation has for isotope separation is of extreme interest to the intelligence community. (wikipedia.org)
  • Magnetic separation is a process in which magnetically susceptible material is extracted from a mixture using a magnetic force. (wikipedia.org)
  • good
  • Some experts regard a six-month separation as good amount of time for a temporary separation, since it is long enough to set up a second household and gain perspective, but not long enough to seem permanent. (wikipedia.org)
  • previous
  • the definitions given here fall into a consistent pattern that relates the various notions of separation defined in the previous section. (wikipedia.org)
  • long
  • As long as there is a VVS and people who want to undermine religious freedom, there will be an Americans United for Separation of Church and State and likeminded supporters who are determined to protect it. (au.org)
  • method
  • Gravity separation is an industrial method of separating two components, either a suspension, or dry granular mixture where separating the components with gravity is sufficiently practical: i.e. the components of the mixture have different specific weight. (wikipedia.org)
  • statistics
  • In statistics, m-separation is a measure of disconnectedness in ancestral graphs and a generalization of d-separation for directed acyclic graphs. (wikipedia.org)
  • In statistics, separation is a phenomenon associated with models for dichotomous or categorical outcomes, including logistic and probit regression. (wikipedia.org)
  • achieve
  • The field of computational auditory scene analysis attempts to achieve auditory source separation using an approach that is based on human hearing. (wikipedia.org)
  • parents
  • It focuses on an Iranian middle-class couple who separate, the disappointment and desperation suffered by their daughter due to the egotistical disputes and separation of her parents, and the conflicts that arise when the husband hires a lower-class caregiver for his elderly father, who suffers from Alzheimer's disease . (wikipedia.org)
  • actually
  • Takagi thus believes that the draconian social class structures imposed by the Separation Edict were actually intended specifically for the buke hokonin, including the wakato, chugen, and komono, and not for most of the individuals engaged in military service. (wikipedia.org)
