Contract award notice: procurement subject hplc apparatus with quaternary system
for the client according to the documentation, including the delivery of the same to the client, which includes installation qualification, operation and performance, and user education clients for doing the same, as well as the issue of the relevant documents certified (certification data of qualification and validation report after installation and commissioning).
For a quaternary system, the twelve binary interaction parameters [A.
The number of such possibilities for ternary system is 6, for quaternary system is 220, and for quinary system is 38 760.
Thus, number of feasible sets of parameter elimination of ternary system is 6, for quaternary system is 128 and for quinary system is 8000.

Three closure equations for the quaternary systems are (Ahmad and Khanna, 2003):
The results of parameter estimation along with the corresponding percentage gain values for the ternary and quaternary systems are given in Table 9 and Table 10, respectively.
This solution combines unsurpassed accuracy and reliability with the full flexibility of a quaternary system
, including gradients, precise buffer blending and method development capability.

Phase diagrams and modeling are the topics of the next chapter, and III-V ternary and quaternary systems
are used as examples.
Further work is needed, however, because calculated mobilities for other ternary systems like AlGaN and quaternary systems
like InAlGaN and InGaAsP are needed.
