  2. High-performance liquid chromatography - Wikipedia

    en.wikipedia.org/wiki/High-performance_liquid...

    The theory of high performance liquid chromatography-HPLC is, at its core, the same as general chromatography theory. [41] This theory has been used as the basis for system-suitability tests, as can be seen in the USP Pharmacopeia, [ 42 ] which are a set of quantitative criteria, which test the suitability of the HPLC system to the required ...

    In reviewing the older leadership theories, Scouller highlighted certain limitations in relation to the development of a leader's skill and effectiveness: [3] Trait theory: As Stogdill (1948) [4] and Buchanan & Huczynski (1997) had previously pointed out, this approach has failed to develop a universally agreed list of leadership qualities and "successful leaders seem to defy classification ...

  4. Functional leadership model - Wikipedia

    en.wikipedia.org/wiki/Functional_leadership_model

    Functional leadership theory (Hackman & Walton, 1986; McGrath, 1962) is a theory for addressing specific leader behaviors expected to contribute to organizational or unit effectiveness. This theory argues that the leader's main job is to see that whatever is necessary to group needs is taken care of; thus, a leader can be said to have done ...

    en.wikipedia.org/wiki/Charged_Aerosol_Detector

    The charged aerosol detector (CAD) is a detector used in conjunction with high-performance liquid chromatography (HPLC) and ultra high-performance liquid chromatography (UHPLC) to measure the amount of chemicals in a sample by creating charged aerosol particles which are detected using an electrometer.

    Functional leadership theory [67] addresses specific leader behaviors that contribute to organizational or unit effectiveness. This theory argues that the leader's main job is to see that whatever is necessary to group needs is taken care of; thus, a leader can be said to have done their job well when they have contributed to group ...

    en.wikipedia.org/wiki/Full_Range_Leadership_Model

    The full range of leadership model (FRLM) is a general leadership theory focusing on the behavior of leaders towards the workforce in different work situations. The FRLM relates transactional and transformational leadership styles with laissez-faire leadership style.

  9. High-performance thin-layer chromatography - Wikipedia

    en.wikipedia.org/wiki/High-performance_thin...

    The spot capacity (analogous to peak capacity in HPLC) can be increased by developing the plate with two different solvents, using two-dimensional chromatography. [8] The procedure begins with development of a sample loaded plate with first solvent. After removing it, the plate is rotated 90° and developed with a second solvent.
