Sampling critical

The depth of the required steps is estimated using the Criticality and Complexity Assessment and may be performed during the early Project Conceptualization stages of a project and reevaluated at Project Initiation. A sample Criticality and Complexity Assessment can be found in Appendix D. 

Coexistence curves can accurately be determined from measurements of the refractive index in the two phases of a flame sealed critical sample. Criticality of the sample is ensured by the equal volume criteria, requiring equal volume of the phases at the cloud point. The Lorenz-Lorentz relation is employed to determine the composition in the coexisting phases. Note, measurements of cloud points for samples of different compositions usually do not suffice to reach the necessary accuracy as minute uncontrollable impurities influence the cloud point temperature.

The nature and distribution of pyrolysis products from a particular sample critically depend largely on the pyrolysis temperature and the specific set of pyrolysis conditions (i.e. temperature rise time, sample size, pyrolyser geometry). Laser pyrolysers are practically the only type of radiative heating pyrolyser with certain applicability. A laser pyrolyser consists of five components (i) laser (ii) fibre optics (Hi) probe for sample introduction (iv) pyrolyser body, containing the pyrolysis chamber and (v) heater of the pyrolysis chamber with dedicated control unit. The laser beam can be focused onto a small spot of a sample to deliver the radiative energy. This provides a special way to pyrolyse only a small portion of a sample. Only the sample itself is... 

Sample critical behavior checklist. Figure 12.10 depicts a comprehensive CBC for recording the results of a coaching observation. This kind of CBC recording sheet should be used after the participants (optimally, everyone in a particular work area) have derived precise behavioral definitions for each category and have practiced rather extensively with shorter CBCs. Such practice enables careful refinement of behavioral definitions and builds confidence and trust in the process.
