1a. ACI: Chromatography \ Mass Spectrometry: ACI: Q-TOF LC/MS, LC-QTOF 6545B

What is it?
Liquid chromatography is a technique in analytical chemistry is used to separate individual components in a mixture with identification and quantification of each component through the Time-Of-Flight Mass Spectrometry.

Manufacturer: Agilent Technologies

Model Name: LC-QTOF 6545B

Applications: Analysis of both targeted and non-targeted analytes compounds.

Instrument Overview: With the Dual AJS ESI source, the nebulizing gas for the reference spray can be switched for high flow or low flow applications. The second sprayer improves the reference mass stability over a wide range of LC conditions. The Q-TOF MS uses a quadrupole (four parallel rods arranged in a square formation), a collision cell, and a time-of-flight unit to produce spectra. Lighter ions accelerate faster down the flight tube to the detector, thus determining the ions’ mass-to-charge ratios.
