Bruker Impact II QqTOF
Bruker Imapct II UHR–QqTOF – This the newest installment to the lab. This is a Ultra-high resolution quadrupole time-of-flight for LC-MS and LC-MS/MS for samples requiring high-resolution analysis (> 60,000). Ideal for complex mixtures and intact mass of large proteins. It also comes equipped with a Dionex UPLC that can run both in UPLC and HPLC mode. We also have the ability to switch between nano-flow and capillary-flow.
Here we show an example of a LC-MS/MS of a tryptic digest from a complex protein mixture. The second image is of intact protein lysozyme showing the 9th charged state isotopically resolved.
