  • Patent number: 11946917
    Abstract: A detection method of polyethylene glycol monomethyl ether residue in medicinal materials is provided, which belongs to a technical field of medicinal chemical component detection, and includes: detecting a residual amount of mPEG-2000 in 3000-3400 small-molecule mPEG-b-PDLLA by high-performance liquid chromatography with an evaporative light scattering detector. The present invention solves a problem that the copolymer polyethylene glycol monomethyl ether mPEG and the product polyethylene glycol monomethyl ether-polylactic acid block copolymer mPEG-b-PDLLA are difficult to be separated in the high-performance liquid chromatography and there is no UV absorption. The present invention also has high resolution, high sensitivity, sufficient reproducibility and sufficient selectivity.

  • Patent number: 8355896
    Abstract: A method of modeling includes quantifying a co-operative strength value for a plurality of pairs of variables, and identifying a clique of at least three variables based on a graph of the co-operative strength values of a plurality of pairs of variables. The method also includes selecting a first pair of variables of the plurality of pairs of variables having a high co-operative strength value. A second clique may also be identified. A model of the first clique and a model of the second clique are made. The outputs of these models are combined to form a combined model which is used to make various decisions with respect to real time data.
