Here you will find the information of mass spectrometry service in the Laboratory of Organic Chemistry (LOC) at the ETH Zurich.From March 01, 2011 we start a fee-based MS service to users outside D-CHAB (price), please contactDr. Xiangyang Zhangbefore you send or bring your samples.

Sample	Infusion	Ionization	Analyzer		Mass Spectra
		ESI; EI/FAB; MALDI	EBE triSector, Qq-TOF, ICR, TOF

LOC MS service lab is equipped with 4 top mass spectrometers:
Waters' Micromass AutoSpec Ultima (EI-triSector) for exact mass determination of volatile organic compounds;
Bruker's solariX (ESI/MALDI-FTICR) for exact mass determination of mid-size compounds;
Bruker's UltraFlex II (MALDI-TOF) for large biooligomers, biopolymers, supramolecular assemblies, and synthetic polymer;
Bruker's maXis (ESI/NanoSpray-Qq-TOF) for exact mass determination and identification of polar compounds.
More details please refer to Instrumentation.

Sample submission is recommended together with the detailed information of the samples. Delivery of uncalibrated spectra is within measuring day. Report for exact mass calibration and interpretation will be delivered in 2-3 working days. Electronic copy in pdf and export will be provided to users per email if required. More information on post-processing of mass spectra will be found under links of MS tools.

Choice of suitable ionization method is the most critical step of mass spectrometrical analysis. The most appliable ionizations at our ms service include EI, ESI(NanoSpray) and MALDI. How to choose a most appropriate ionization method for your samples please get instructions from MS team or refer to the past experience from your group. For some "difficult" samples it is strongly recommended that users bring available info in literatures.

Other important info can be found under the link of FAQ or MS links. If you have more questions, please contact MS service team.
