Improved separation of poly(butylene glycol) oligomers on a C18 column by gradient reversed-phase liquid chromatography and fine-tuning of the organic modifier system

A New Methodology for the Synthesis of Fluorinated exo‐Glycals and Their Time‐Dependent Inhibition of UDP‐Galactopyranose Mutase

“…Therefore, liquid chromatography at critical conditions (LCCC) is a more suitable technique, separating homologues based on one comonomer, and being independent of the other comonomer 2, 5, 11–13. The development of LCCC can be seen as a result of intensive studies of (reversed‐phase) LC with gradient elution, which may be used for further polymer separation, yielding chromatographic resolution based on complete chemical composition 2, 5, 14–21. Even more enhanced separation is obtained by means of two‐dimensional chromatographic techniques 22–24.…”

Characterization of the chemical composition of a block copolymer by liquid chromatography/mass spectrometry using atmospheric pressure chemical ionization and electrospray ionization

“…2,5,[11][12][13] The development of LCCC can be seen as a result of intensive studies of (reversed-phase) LC with gradient elution, which may be used for further polymer separation, yielding chromatographic resolution based on complete chemical composition. 2,5,[14][15][16][17][18][19][20][21] Even more enhanced separation is obtained by means of two-dimensional chromatographic techniques. [22][23][24] LC in general is mostly used for the determination of the compositional distribution of functional end groups and the polymer backbone of addition polymers.…”

Εφαρμογές χρωματογραφίας hplc στον προσδιορισμό φαρμακευτικών ουσιών και συστατικών τροφίμων με εξατμιστικό ανιχνευτή σκέδασης ακτινοβολίας

“…Οι μέθοδοι αυτές βρίσκουν εφαρμογή σε προσδιορισμούς αντιβιοτικών, υδατανθράκων και λιπιδίων σε πλάσμα, ούρα και ιστούς. [154][155][156] Σχετικά με τον προσδιορισμό των πολυμερών ο ανιχνευτής ELSD αποτελεί ενδεδειγμένη μέθοδο…”
