  • Patent number: 10663438
    Abstract: Disclosed herein are compounds and methods for identifying and quantifying a metabolite or breakdown product of PEG. A sample may be assayed for PEG metabolites or breakdown products using liquid chromatography combined with mass spectrometry. Derivatization of the PEG metabolites or breakdown products within the sample with pentaflurobenzoyl chloride in conjunction with negative chemical ionization mode liquid chromatography optimizes the assay.
    Type: Grant
    Filed: August 3, 2018
    Date of Patent: May 26, 2020

  • Publication number: 20080012280
    Abstract: A recovery spade that is adjustably coupled to a rescue vehicle to thereby maximize traction during rescue operations. The recovery spade includes an anchor blade and a hollow support member. The anchor blade includes a plurality of holes for selective connection to the support member at differing heights via a pin. The anchor blade further includes an anchor portion with teeth at one end for engaging the ground to effect the traction and coupling holes at the other end for selective connection to the anchor blade at differing angles.
