Bruker HCT-Ultra ETD II

More Information


Now available from KRSS is a used, fully refurbished and serviced Bruker HCT Ultra ETD II and Dionex Ultimate 3000 with UV and N2 generator.

The LC system is composed by the following units; Solvent Rack / Degasser (SRD3600, Pumps, DGP-3600M, VWD3400 Detector, Flow manager control (FLM3100 nano 2X2P-10P), Autosampler (WPS-3000TPL nano, cap autosampler).

For today’s challenges in proteomics and metabolomics work, the HCT series is best prepared to partner the researcher in the fields of: Protein ID and Detailed Characterization Metabolite ID and Profiling General Chemistry LC/MSn.

Full scan MS sensitivity is a must for all data dependant experiments, it enables intelligent acquisition of MS/MS data especially on low abundance precursor ions.

Together with the dramatic increase in MS/MS data sets per unit time, HCT series instruments assure maximum information from your samples, optimizing protein identification and database scoring.

HCT series spherical ion traps provide great MS and MS/MS spectra quality – in terms of mass resolution, sensitivity and accuracy throughout a wide mass range at ultra fast HPLC speed.

ETD II is an electron transfer dissociation module for Bruker’s HCTUltra high capacity ion trap.

It is based on a negative chemical ionisation source with increased ETD/PTR reactant ion generation, resulting in rapid characterisation of PTMs such as phosphorylations or glycosylations at sub-fmol sensitivity.

ETD is a very powerful peptide and protein fragmentation technique that preserves functionally important post-translational modifications (PTMs), such as phosphorylations or glycosylations. With ETD in a spherical high-capacity ion trap, the sequencing and identification of proteins, as well as the identification and localization of PTMs are facilitated with greatly improved scores and confidence.

HCTUltra’s inherent m/z range of greater than 3,000 and its mass resolution that can resolve three+ and four+ charge states of peptides on the fly at full analytical speed means ETD/PTR on the HCTUltra can be used for up to 12 kDa proteins and beyond.
