Instrument Use Policy
- All users must go through instrument orientation with lab personnel. This usually requires about one hour.
- All users must fill out and have the PI of their project sign a Use Registration form. You must provide a valid PTA number for instrument recharges. The PTA number you specify will be billed for your instrument usage. If you wish a different PTA number to be charged, fill out a new form and send it to the EAC before the end of the month you want the new number to take effect.
- Keys may be issued at the discretion of the EAC Director.
- All users must sign into the log book before beginning to work on the instrument.
- All users must verify cleanliness of the instrument before and after running their own samples.
- Users should notify EAC personnel if there is any condition that prevents use of the instrument or endangers the life and safety of those present in the lab.
- Users who intentionally or neglectfully misuse, damage, or contaminate the instruments will lose their privelege to use the instruments, and will be billed for any repairs, cleanup or decontamination. This includes but is not limited to physical damage, chemical contamination, or corruption of the data systems.
Guidelines for Acknowledgement in Print
The Environmental Analysis Center is a shared chemical instrumentation facility. The instrumentation in the EAC has been purchased with funds donated by the Bank of America Foundation. As new chemical instrumentation evolves, and as the equipment we have wears out, we expect to approach foundations and funding agencies for more funds in the future. To assure the greatest possibility of success in that endeavor, we ask for your help in documenting the benefit the EAC has provided to your research program through acknowledgement in the publications that include data obtained on EAC instrumentation.
We ask that you include one of the following acknowledgements any time EAC instruments are involved in a project.
"______ instrumentation at the Environmental Analysis Center at the California Institute of Technology was used in this work."
or
"This project benefited from the use of instrumentation made available by the Caltech Environmental Analysis Center."
The EAC requests a hard-copy reprint of any publication using data obtained on EAC instruments.
If you receive assistance from EAC staff beyond training and selection of a standard analytical method, please follow the guidelines set forth in the Instructions to Authors of the journal submitted to, or the relevant professional society.

Usage Fees
All users are charged fees for the use of EAC instruments. Fees are charged to cover costs of consumables and repairs. Recharge rates decrease after the first 10 hours used each month.
Please note that there is a minimum per-visit charge specific to each instrument. In addition, the per-visit minimum is also the minimum increment for additional time.

Notes:
There is no charge if an instrument problem prevented you from getting results.
Uses or users that detrimentally affect others will be charged for costs incurred and may be requested not to return. Charges will include staff time ($60.00) required to correct contamination or damages.
