MS1 Oligonucleotide Characterization Using LC/Q-TOF with HILIC Chromatography
June 20th 2023In this application note, LC separation and MS1 mass identification of a variety of oligos without the use of ion‑pairing reagents is demonstrated. The LC separation allows subsequent positive mode use with little to no flushing or hardware changes. This HILIC-based method uses an Agilent InfintyLab Poroshell 120 HILIC-Z column and MS-friendly ammonium acetate-based mobile phases. The samples were analyzed on an Agilent 1290 Infinity II LC system and a 6545XT AdvanceBio quadrupole time-of-flight mass spectrometer (LC/Q-TOF).
Oligonucleotide Characterization by Agilent 1290 Infinity II Bio LC and 6545XT AdvanceBio LC/Q-TOF
June 20th 2023Characterization of oligonucleotides requires robust analytical instrumentation and methods as well as ease-of-use data analysis tools. Biocompatibility mitigates non-specific sample binding to flow path and it ensures the integrity of biomolecules and robustness of the system. In this study, two workflows, the Target Plus Impurities (TPI) and Sequence Confirmation workflows in Agilent MassHunter BioConfirm software, were carried out to characterize two oligonucleotide samples.
MS/MS Oligonucleotide Sequencing Using LC/Q-TOF with HILIC Chromatography
June 20th 2023In this application note, the determination of oligo sequence confirmation using HILIC LC and high-resolution MS/MS data is described. As with the previous studies, an InfinityLab Poroshell 120 HILIC-Z column was used along with an Agilent 6545XT AdvanceBio LC/Q-TOF mass spectrometer.
