<p><em>Note:</em> The extraction efficiency module makes the default assumption that all extraction iterations are equivalent
in duration. However, if this is not the case, the module can still be used, although the input must be modified. Because of
approximate scaling relationships, a single step extraction will be equivalent to an iterative extraction provided the
the total solvent used and total time duration are also equivalent. For example, a three step iterative extraction using 10 ml
for each iteration with time
points of 24, 72, and 168 hours can be modeled using a single step extraction (# of iterations = 1) with 30 ml of solvent
(3 x 10 ml) for 168 hours. This same approach can be used if the solvent volumes are different for each extraction
iteration, however unlikely this scenario may be.</p>

<p><em>Diffusion coefficient (cm<sup>2</sup>/s)</em> - Please enter a diffusion coefficient in square centimeters per
second. </p>
<p><em>Note:</em> The diffusion coefficient (D) is a material property that reflects the rate at which a compound
can migrate through the matrix - formally it is a proportionality constant relating concentration gradient to flux.
The value of D can vary dramatically depending on the polymer matrix and extractable compound, and even extraction solvent,
for systems that exhibit significant swelling. If you are interested in comparing the extraction efficiency for a specific
compound, we recommend estimating D for the system of interest based on available data. For comparing experimental conditions
for extractable compounds in general, we recommend probing an appropriate range of D for the systems of interest. For example,
compounds in the Mw range of 200 to 1200 g/mol extracted from HDPE have been found to lie in the range of 1e-9 to 1e-13 cm2/s for IPA
and 1e-7 to 1e-9 cm2/s in hexane [1].</p>

<p><em>Partition coefficient</em> - Please enter a partition coefficient of interest for your system.</p>
<p><em>Note:</em> The partition coefficient (K) is a material property that reflects the ratio of the
concentrations of extractable compound in the polymer matrix and extraction solvent in equilibrium. As such, the value of K can vary
dramatically depending on the extraction materials. If you are interested in comparing the extraction efficiency for a specific
compound, we recommend estimating K for the system of interest based on available data. A number of empirical approaches
have been developed for this purpose, e.g. [1,2]. However, these approaches do not necessarily capture the potential impact
of temperature and matrix swelling, which can both dramatically impact this quantity [3-5]. For comparing experimental conditions
for extractable compounds in general, we recommend probing an appropriate range of K for the systems of interest. We note
that the range of interest will be restricted because large values of K will not permit substantive quantities of a compound to
be extracted over relevant timeframes and for systems with small values of K extraction efficiency will be dictated solely
by kinetic limitations. </p>
