MS Platform Policies
General Policies
- A Financial Agreement (internal users) or Services Order Form (external users) must be in place before services commence.
- All PIs are responsible for maintaining active financial agreements in the Lab Management Portal, including setting up agreements for new grant awards and adding and removing participants as the research group changes over time.
- All new projects must be initiated as a consultation request in the Lab Management Portal including requests to become an expert or applications superuser.
- Any samples requiring BSL2 and above handling procedures must be accompanied by an Exposure Control Plan.
- Calibration solutions, MS grade solvents, solvent bottles, and autosampler vials will be provided by METRIC. All other consumable must be provided by or charged to the user.
- METRIC does not allow the use of any solvents below MS grade, ion pairing reagents, or any unusual modifiers without permission.
- METRIC provides all gas cylinders required to operate instrumentation; only METRIC staff and expert users are permitted to change out gas cylinders.
- Google Drive and Dropbox are the only allowed data transfer mechanisms.
- No External Hard Drives or Flash Drives, Web Surfing or Program Downloads on Data Acquisition Computers.
- No remote access to data acquisition computers outside of your instrument reservation period.
- Weekly restart for update installation required for all data acquisition computers.
- Training of clients on open source data analysis software or purchased copies of licensed software will be approved on a case by case basis for METRIC collaborators only
- All samples submitted to METRIC must be labeled clearly and include a detailed description of what each sample ID is as well as any protocols for processing that the samples were subjected to; samples will be stored by METRIC for no longer than 1 month after project completion.
- METRIC will provide raw data files to clients for transfer to their own storage device; METRIC will store raw and processed data for a maximum of 1 week post-analysis, after which METRIC assumes no responsibility for data storage.
- All users agree to cite METRIC in any publications or grant proposals for which data was collected in METRIC.
- Authorship of scientific papers should include individuals who make meaningful and substantive contributions to the intellectual content of the work to be published.
Facilitated Use Policies
- Training: Initial training by METRIC staff, typically consisting of one to three training days, will be charged at an hourly rate; training is limited to two main users per research group; any METRIC assistance requested after training will also be charged.
- Routine Maintenance: METRIC is responsible for routine maintenance for all MS (system calibration, ITT and sweep cone cleaning) and LC (check valve sonication, purging and flushing of all mobile phase lines) components.
- Service Calls: Service issues should be should be communicated to METRIC staff.
- Emergency Procedures: in the event of a power outage (planned or unplanned), METRIC will be responsible for any necessary shut down and start up procedures.
- Expert Users: Modifications of the above policies may be permissible for users with documented expertise.
Sample Preparation
- METRIC pipettes and balances are calibrated twice annually.
- Sample storage freezers are on generator power and serviced annually.
- Water purification systems are serviced annually.
- Speed-vacs have oil-free pumps and are maintained with coolant and routine cleaning of the solvent trap.
- Positive pressure manifolds and N2 evaporation units are only supplied with grade 5 N2.
- SPE vacuum manifolds are rinsed and stored properly after each use; replacement parts are kept on hand and when used are reordered to maintain inventory.
ICP-MS Policies
- All sample preparation should take place in the user lab and fully prepped samples only should be brought to the ICP-MS instrumentation laboratory.
- Samples should be as clean as possible and filtered using a ca. 1 μm filter.
- Concentrated strong acids (>30% v/v) should not be handled or stored around the instrument or in the instrument laboratory (i.e., HCl, HNO3).
- Expert users should run a Performance Report before and after their analysis to document instrument performance
