The uses of BET, CV, EIS, FTIR, Raman, SEM, TEM, XRD, and mass spectrometry

February 14, 2024

1. BET: mainly used to test the specific surface area of materials, which can provide information on the specific surface area of materials.


2. CV: the CV curve can be tested to obtain a lot of information, such as the required electrodeposition voltage, current, and the semiconductor industry can obtain DC bias voltage.


3. EIS: EIS is an electrochemical impedance spectroscopy test that can obtain electrode potential and impedance information, thereby simulating the internal series resistance, parallel resistance, and capacitance related information of the system.


4. FTIR: mainly used to test polymer organic materials, determine the presence of different polymer bonds, and determine the structure of the material. Such as single keys, double keys, and so on.


5. Raman: used to determine the structure of materials by measuring rotational energy and vibrational energy.


6. SEM: surface morphology and morphological characteristics of materials. By cooperating with EDX, information on the elemental composition of materials can be obtained.


7. TEM: surface morphology and crystallinity of the material. By cooperating with EDX, the elemental composition of the material can be obtained.


8. XRD: mainly tests the physical properties and crystal structure of materials. Advanced XRD can also test the composition of materials with different crystal forms.


9. Mass spectrometry: mainly used to identify the chemical composition of materials, including liquid phase mass spectrometry and meteorological mass spectrometry.
