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 preparation: Please measure the length, width and weight of the sample by yourself and record it on the application form. Please encapsulate the powder sample in a capsule or straw by yourself. Liquid samples are not subject to measurement for the time being. The sample is as follows:
Powder: placed in capsule (needs to be weighed separately from the capsule to know the correct weight of the sample)
Single crystal: it is necessary to determine the axial direction before measurement
Film: The measurement direction of the magnetic field and film must be informed (the length and width of the film must be less than 2.5mm*2.5mm)

2. Sample properties: Please describe in detail, whether it is toxic or not, and whether the radioactivity is easily oxidized, so that the delivered samples can be processed properly immediately. Please also describe the possible characteristics of the samples, so that if there are any discrepancies during measurement, they can be immediately identified. Inform users.

3. Sample name: Please indicate the ingredients clearly. Please clearly state the measurement items "temperature", "magnetic field" and "magnetic decay time".

4. Sample recycling: If you want to send back samples, please attach a self-addressed envelope and a stamp of 28 yuan.
Note: Since the upper limit of measurement of this instrument is 1emu, if your sample has strong magnetism, the weight of the powder should not exceed 3mg.

Instrument operation reservation:

Please go to the "National Science and Technology Council The Instruments Informantion System" to make an appointment.

P.S.:
Level A: Open to students who need to use it. They can operate it on their own after training and assessment.
Level B: Each professor assigns one student to apply for training. The other students of the professor must be operated by the trained students. If a professor has too many students using the instrument, he or she may apply to the person in charge of the instrument to increase the number of students receiving training. .
Level C: The person in charge of the instrument selects a number of students recommended by the professor to receive training. After passing the assessment, they can operate the instrument themselves and be responsible for entrusted service work.
Level D: The technical staff of this laboratory accept entrusted services and are not open for use.

3. Sample name: Please indicate the ingredients clearly. Please clearly state the measurement items "temperature", "magnetic field" and "magnetic decay time".
