1. GC-MS (gas chromatography-mass spectrometry)
Agilent 7890B GC-5977A MS system
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.
2. HPLC-UV (High performance liquid chromatography-ultraviolet)
3. LC-MS/MS (Liquid chromatography tandem mass spectrometry)
YoungLin YL9300 HPLC
HPLC is a technique in analytical chemistry used to separate, identify, and quantify each component in a mixture. It relies on pumps to pass a pressurized liquid solvent containing the sample mixture through a column filled with a solid adsorbent material. Each component in the sample interacts slightly differently with the adsorbent material, causing different flow rates for the different components and leading to the separation of the components as they flow out the column.
Agilent 1260 LC-Sciex 3200 Qtrap MS system
LC-MS is an analytical chemistry technique that combines the physical separation capabilities of liquid chromatography with the mass analysis capabilities of mass spectrometry. LC-MS is a powerful technique that has very high sensitivity, making it useful in many applications. Its application is oriented towards the separation, general detection and potential identification of chemicals of particular masses in the presence of other chemicals
3. HPLC-Q-TOF (High Performance Liquid chromatography Quadrupole Time of Flight)
Agilent 1290 LC 6545 Q-TOF MS system
Time of flight (TOF) is a property of an object, particle or acoustic, electromagnetic or other wave. It is the time that such an object needs to travel a distance through a medium. The measurement of this time (i.e. the time of flight) can be used for a time standard (such as an atomic fountain), as a way to measure velocity or path length through a given medium, or as a way to learn about the particle or medium (such as composition or flow rate).
