LC-MS/MS Method Development

What Is LC-MS?

(LC) Liquid Chromatography:

Chromatography is a separations method that relies on differences in partitioning behavior between a flowing mobile phase and a stationary phase to separate the the components in a mixture.
A column holds the stationary phase and the mobile phase carries the sample through it.
Sample components that partition strongly into the stationary phase spend a greater amount of time in the column and are separated from components that stay predominantly in the mobile phase and pass through the column faster.

(MS) Mass Spectrometry:

Mass spectrometers use the difference in mass-to-charge ratio (m/z) of ionized compounds to separate them from each other.

Compounds have distinctive fragmentation patterns that provide structural information to specifically detect compounds.

Types of Mass Spectrometers

• LC-MS (Single Quadrupole)
• LC-MS/MS (Triple Quadrupoles)
• LC-Q (Ion Traps, Linear Ion Traps)
• LC-Q-TRAPS (Quadrupole Linear Ion Traps)
• LC-TOF-MS (Time-of-Flight)
• MALDI-TOF-MS
• Q-TOF-MS (Quadrupole Time-of-Flight)
• FT-MS (Fourier Transform)
• Others
