3. Introduction

  Gas chromatography-mass spectrometry (GC-MS) is an analytical method that combines the features of gas chromatography and mass spectrometry to identify different substances within a test sample. Applications of GC-MS include drug detection, fire investigation, environmental analysis, explosives investigation, and identification of unknown samples. GC-MS has been regarded as a "gold standard" for forensic substance identification because it is used to perform a 100% specific test, which positively identifies the presence of a particular substance. A nonspecific test merely indicates that any of several in a category of substances is present. Although a nonspecific test could statistically suggest the identity of the substance, this could lead to false positive identification. However, the high temperatures (300°C) used in the GC-MS injection port (and oven) can result in thermal degradation of injected molecules, thus resulting in the measurement of degradation products instead of the actual molecule(s) of interest.


4. Service

5. Precautions

  • Organic liquid with a volume over 20 ml.
  • The sample measurement surface should be as flat as possible.
  • The gassing or electrochemical cell used for on-site analysis needs to be approved by the center.


6. Opening hours

   (Open all hours)


7. Precautions for reservation

  • After being authenticated by the center, you can register an appointment account online and make an appointment online.
  • If there is a need for a long-term on-site electrochemical experiment, the facility administrator must be informed 3 days before the experiment, and an appointment should be made during the time slot (優先 In-situ) in the table above.
  • If the time period (優先 In-situ) is not used, it can be used for general operations.


8. Charging Information


  • If you do not pay the fee for more than two weeks, you will be notified in advance. If the payment is still in arrears, your teacher and all laboratory personnel will stop entering the HG card machine control.
  • The charging method is mainly based on the transfer of funds planned by the
    Ministry of Science and Technology. You can also apply for a pre-issued
    receipt with the center and pay in cash through the online payment platform.


9. Delegated operation

  • For those who need entrusted operation, please contact the equipment administrator to discuss the details of analysis.
  • Please fill in the form委託操作服務申請表(下載), and please send it to the central office equipment administrator, or email to alex.chl.cera@gmail.com after scanning. The center will help arrange the OEM time.
  • Operation time: Mainly Monday and Tuesday morning 09:00-13:00 (The actual operation time is mainly notified by the equipment administrator.)


10. Relevant regulations on self-operated machine training

  • Users must participate in radiation protection education and training for more than 3 hours, and obtain a radiation education and training certificate, or have received more than 3 hours of radiation protection education and training
    conducted by other radiation protection training companies approved by Atomic Energy Council, Executive Yuan.
  • The training methods includes basic principles and training (2hrs), practice (2hrs), certification (2hrs). The fees are as shown in the table above.
  • Users must fill in儀器設備訓練課程申請表(下載), and delievery to the center. Those who have been certified as qualified have to sign『國立成功大學跨維綠能材料研究中心儀器使用承諾書』(下載)才before using the machine.
  • Permission
    • Level A: Accept the training, practice, and certification courses of the center, and obtain certification and 100 hours of use. After being approved by the equipment manager, you can become an A-level user. They can operate the instruments by themselves, be responsible for instrument training courses, entrust service work, and maintain the functionality of the instruments and equipment, and have the highest authority to use the instruments and equipment.
    • Level B: Requires central training, hands-on, certification courses, and certification. The instrument can be operated by itself.
