The poster highlights some of the many innovations implemented in this unique instrument: Minimized volumes save cycle time and contaminated surface. An optimized wash procedure for most effective and quick cleaning. An injection mechanism that protects hydrophilic analytes from the harms of pressure fluctuations. And waste liquid management that keeps your lab bench clean and tidy!
If you are in Atlanta for the annual ASMS conference next week – and we think you should! – be sure not to miss the following events and contributions!
- Revolutionary Low-Flow HPLC is on display at our booth no. 709 – see the integrated LC-MS front-end we’ve been working on lately, and which everyone is talking about!
- See our corporate poster (CP42) – and take a copy home – if you are interested in innovative approaches which improve the power of separation – and leverage the integration of the best low-flow HPLC pumps and the most innovative autosampler in existence.
- The Future of LC-MS is what we will talk about at the Breakfast Meeting on Tuesday and Wednesday at 7 – 8:15 am – hosted by our friends at New Objective. Do not miss our presentation on Wednesday, when we will talk about integrated solutions that minimize dead volumes, cycle time, retention time CV, carryover – and also the time it it takes from unboxing the LC system to seeing the first peaks from your mass spec!
- We are happy and proud that our friends from New Objective will be presenting our Zirconium LC-MS Front-End at their booth no. 324 as a part of our shared bigger vision – The Future of LC-MS! Be sure to visit their booth as well!
- Capitalizing on the separation power of Zirconium HPLC pumps, Sound Analytics developed their own highly integrated Platform for Trap-and-Elute Microflow LC-MS/MS. Be sure to check out their poster (WP247)!
- Bruker will show their own excellent integrated solution based on a Prolab Zirconium pump, nanoElute, at their Hospitality Suite. Go and ask them about it!
- Also, if you are looking for more reference data from Zirconium pumps, there are a lot of posters on display which make use of Bruker’s nanoElute nano-LC system. Just enter “nanoElute” as a search term in the ASMS conference planner, and you will have plenty to read!
In any case – we are looking forward to seeing you, old and new contacts. If you cannot find us at booth 709, please drop us a line and we will find a time and place to meet!
- Tuesday October 16, 5:00 PM – 6:00 PM:
Workshop with Sound Analytics. Let’s talk about this!
- Wednesday October 17, 1:15 PM – 2:15 PM:
Workshop “Leading High-Performance Nanoflow and Microflow LC-MS into the Future”
- Wednesday October 17, 2:30 PM – 3:45 PM:
Innovator Award Session (Track 7) Presentation, “Fast HPLC Injections, Rethought”

Oral WOB pm 2:40pm, Wednesday – Oceana 7: Trapped ion mobility mass spectrometry for improved sensitivity and fastest proteomics
A typical setup as seen in our previous application note employs three pumps – one for loading the sample out of the autosampler’s sample loop, one for diluting the sample’s organic solvent with water for trapping, and one for the analytical gradient, eluting the concentrated analytes off the trapping column onto an analytical column for separation.
We optimized this design a little, replacing the loading and dilution pumps by a single pump. See how it works in our new animation (turn on sound and/or subtitles):
Amyloid peptides (Abeta; Aβ) result from cleavage of amyloid precursor protein (APP) by beta and gamma secretase.The 42-amino acid variant, amyloid β peptide 1–42 is a widely accepted key biomarker for Alzheimer’s disease (AD) together with the total tau (T-tau) and phosphorylated tau (P-tau) protein. Diagnostic accuracy of the Aβ 1–42 /Aβ 1–40 ratio in cerebrospinal fluid (CSF)
compared to the concentration of Aβ 1–42 alone was found to be even more significant.
Currently these peptides are analyzed routinely in CSF by immunoassays, but in recent years, liquid chromatography tandem mass spectrometry (LC-MS/MS) has been investigated for the quantification of Aβ1-38, Aβ1-40, and Aβ1–42.
