PSU BioAnalytical Mass Spectrometry Facility
Visit our Open House the last Friday in January, April and October
We invite you to come by for a tour of our open access fee-for-service Facility for the identification & quantification of small molecules. New users feel free to bring a sample for high resolution exact mass analysis. Please bring samples in methanol or water at 10uM; fill in a registration form ahead of time and email to firstname.lastname@example.org. Pay parking is available at PSU Parking Structure 3.
The BioAnalytical Mass Spectrometry Facility is housed in the Chemistry Department. A role of the Facility is to provide training for investigators and students on use of a ThermoElectron LTQ-Orbitrap Discovery high resolution mass spectrometer with a dedicated Accela HPLC system. Another role of the Facility is as a service laboratory to provide high resolution accurate mass analysis for samples submitted for formula determination.
Fees are billed on an hourly basis for training or instrument usage or on a per sample basis for samples submitted for analysis by facility personnel as outlined in the current rate sheet.
User operated instrument time or sample analysis by facility personnel should be scheduled (see below) and requested ahead of time through submission of registration form.
Please indicate the date of usage and any solvents that will be required in email header.
Rules for Scheduling
- Minimum instrument usage is 1 hour.
- You will be charged the time you have the instrument reserved for (and it is not available to other users) as well as any time used in excess of the reserved time.
- If you cancel or change your time 24 hours ahead of usage, you will not be charged. If you cancel within 24 hours, you will be charged the reserved time.

Description of Services
Training for the LC-MS/MS is available that will enable the individual to perform LC-MS/MS analysis. This training is required before an individual is allowed to analyze their own samples. Training will be split into two sessions (1) analyzing samples using only the MS (2-3 hrs) and (2) analyzing samples in an automated manner using LC-MS. Topics covered include: an overview of ESI-MS/MS, operation of the LC-MS/MS system and an introduction to Excalibur instrument software (including data analysis). Users are encouraged to bring their own samples to the training. To schedule training please email firstname.lastname@example.org or call 503.725.8733.
User Operated Instrument Time:
Individuals who have successfully completed training can schedule and request instrument time. To request instrument time a registration form MUST be emailed to email@example.com at least 24 hours before use. Individuals must supply their own column; solvents and buffers will be provided by the Facility for a charge of $2.5 per 50mL. Autosampler vials/caps are also available for a charge of $1, as well as inserts for a charge of $1. Overall charges will reflect instrument time plus consumables.
Samples submitted for high resolution accurate mass analysis (mass accuracy within 4 ppm):
Accurate mass analysis is provided by Facility staff for molecular formula determination. Samples received between 10am and noon when Dr. Debarber is present in the MS lab (Science Research and Teaching Center, Room 469) will be analyzed on the same day. Please see online scheduler for Dr. Debarber’s availability regarding sample drop-off.
