3. Energy Dispersive Spectrometer(EDS) & Wavelength-dispersive X-ray spectroscopy(WDS)
4. Non-conductor test piece plated with carbon, gold, platinum
Note: Magnetic, organic, polymer materials and biological samples are not within the service scope of this system.

System opening level:

This system is divided into the following three levels:
Level A: Able to operate completely independently (limited to students at graduate school or above)
Level B: only knows basic operations (SEI & EDS) and needs to be accompanied by an administrator (limited to students above the graduate school on campus)
Level C: Commissioned operations (on campus, academia, and industry commissions)

Charges:

Academia-There are planners from the National Science and Technology Council

Level A/Level B License

P.S.:
1. This system is based on a time period. A time period is 3 hours, and the maximum number of test pieces is 6. Any excess will be charged additionally based on the usage hours.
2. WDS needs to be billed separately due to the long measurement time. Please call the administrator for detailed billing methods.
3. All of the above will charge an additional handling fee of 20 yuan (limited to one experiment).
4. If the measurement cannot be carried out or is temporarily canceled due to personal factors, the center will charge a cost of NT$300 per session.

Opening schedule:

Entrusted operation service method:

1. Please go to the "National Science and Technology Council The Instruments Informantion System" to make an appointment and download the experiment application form.
2. Complete the experimental application form in detail and send it electronically to brucel in@gms.ndhu.edu.tw.
3. Print and send (send) a paper experiment application form (signed by the client and supervisor) and samples to the National Dong Hwa University High-valued Instrument Center.
4. Confirm the experimental conditions with the administrator within three days after the experiment application form is sent.
5. When the experiment is completed, Donghua Guiyi Center will send a payment notice to the scheduled project leader.

Sample specifications:

1. Sample type: powder: about 5mg; film or block: about 5 x 5 x 2 mm in size.
2. Sample properties: Magnetic, organic, polymer materials and biological samples are not within the service scope of this system.
    Please dry the test piece before operation, and vacuum the embedded sample in advance to facilitate the vacuuming time.
3. Sample recycling: If you want to send back samples, please attach a self-addressed envelope and a stamp of 28 yuan.
