1. The Agilent 1100 Series LC/MSD is a quadrupolar-based atmospheric pressure ionization (API) instrument capable of electrospray ionization (ESI) and atmospheric pressure chemical ionization (APCI).
2. LC/MSD can handle normal HIGH performance liquid chromatography flow rates (1 ml/min) without splitting effluent, with minimal adjustability of spray chambers.
3. It provides the dynamic range and repeatability required for most quantitative applications.
4. In SIM mode, it has high sensitivity.
5. For compounds lacking strong chromophore, it provides detection limits that other detectors cannot achieve.
6. By providing a unit mass resolution of M/Z 3000, LC/MSD allows characterization of large proteins above 60,000 KDalton.
7. Extending the mass range to 3000 also facilitates the study of modified proteins with charge distribution above M /z 2000, such as glycoproteins.
