Analytical Method For Residues in Meat
The determinative procedure for the analysis of ractopamine residues in tissue can be performed, using liver or muscle as the target tissues, by high performance liquid chromatography (HPLC) with fluorescence detection. The confirmatory method include reversed-phase HPLC/electrospray ionization triple tandem quadrupole mass spectrometry (LC/ESI-MS-MS). The limit of quantification (LOQ) of the drug using LC/MS was shown to be 1 ng/g.

“I have seen too much not to know that the impression of a woman may be more valuable than the conclusion of an analytical reasoner.”
—Sir Arthur Conan Doyle (1859–1930)
“Argument is conclusive ... but ... it does not remove doubt, so that the mind may rest in the sure knowledge of the truth, unless it finds it by the method of experiment.... For if any man who never saw fire proved by satisfactory arguments that fire burns ... his hearer’s mind would never be satisfied, nor would he avoid the fire until he put his hand in it ... that he might learn by experiment what argument taught.”
—Roger Bacon (c. 1214–1294)
“You were born into a different world that will present you with different gifts and challenges. A new vision of manhood will be called for that does not tie so closely into the more aggressive and competitive residues of our male character. You will need to search out new ways of expressing strength, showing mastery, and exhibiting courage—ways that do not depend upon confronting the world before you as an adversary.”
—Kent Nerburn (20th century)
“A man loves the meat in his youth that he cannot endure in his age.”
—William Shakespeare (1564–1616)
