The charge of the EPMA use is needed for the maintenance of our instrument and accessories. The rates (see table below) depend on the type of user, time used during workday or weekend, assisted or unassisted work, etc. Booking (and invoicing) is made per session or/and a fraction of session (unit price per session in the table below), where three types of sessions cover one full day of using the EPMA:

    • Session 1 (Morning session): from 9 am to 1 pm (4 hours)
    • Session 2 (Afternoon session): from 1 pm to 5 pm (4 hours)
    • Session 3 (Evening/Overnight session): from 5 pm to 8 am next day (15 hours).

The EPMA use for a fraction of session (E.g. 3 hours of unassisted work in the afternoon session during the work day), is invoiced as a fraction of that session (E.g. price per session * 3/4).  The same principle applies to use the automate overnight runs. If the evening/overnight session starts at 5 pm and ends at 1 am (8 hours), the price would be the session rate * 8/15). This is equivalent of using the hourly rate ( see table below).

The users who would need to acquire data using EPMA multiple times or on a regular basis are encouraged to go through training sessions at the beginning. After training is complete, the users should continue the EPMA work unassisted. If assistance is needed for a full session, the assisted time will be charged.

* Rates for assisted EPMA time.

** External academic users should contact the Lab manager for booking Weekends and Public Holiday EPMA time and rates.

***Prices excluding sale tax. An amount equal to 8.25% from the invoice will be additionally charged as sale tax for users outside the academic system. The prices are negotiable, based on the type and complexity of each EPMA project and the time required for data acquisition, exporting reports etc.

Please contact the Lab Manager (g.costin@rice.edu).

Weekend and Public Holiday: Session 3 during weekdays and Sessions 1, 2 and 3 during weekends are not assisted. Bracketed are hourly rates. For booking assisted EPMA work during evenings or weekend sessions, please contact the Lab manager. Only users with experience on our instrument will conduct unassisted work during evening sessions and weekends or public holidays. Inexperienced users who need to book the EPMA for weekend time need to be assisted by the Lab Manager. In this case the rate per session is doubled compared to the one showed in the table above.

An additional charge as “Operator time” ($20/h) will be incurred in addition to the assisted rate when samples are sent directly to the lab for analyses (no user present and the analysis is conducted by the lab manager).

Any first-time academic user, if books and uses the microprobe for at least 3 full days in a raw, gets his/her first Session (it should be the session 9 am-1 pm) free of charge. This session consists of training on the microprobe software, sample navigation, tests on his/her own samples, new calibrations if needed etc.

External academic users having on-going research projects or collaborating with Rice faculty or Research Scientists (the EPMA work is part of collaborative work and publications) qualify for internal rates (Category 1 in the table above).

During unassisted instrument time, the user (and his/her P.I.) is liable for any damage resulted on the EPMA instrument and lab.

Carbon coating cost

One carbon coating batch cost is $20, for any user.
