What is GC-MS Agilent?

What is GC-MS Agilent?

Agilent has led innovation and performance in gas chromatography/mass spectrometry (GC/MS) for over 40 years, from the first benchtop Agilent GC/MS through to the MS/MS-capable GC/Q-TOF dedicated to GC.

How much is an Agilent GC-MS?

Agilent’s GC-qTOF has a list price of about $375,000, Sheehan says, which is four-to-five times more than a single-quad system.

What is a GC-MS instrument?

What are GC MS Instruments Used For? Gas chromatograph mass spectrometers are generally used to analyze small, relatively non-polar compounds, and are widely used in forensics, food safety, environmental monitoring, and petrochemicals, among others.

What are the main parts of GC-MS?

It consists of three main components: 1) an injector, which is a port meant for injecting the samples into the GC, 2) a column in which the analyte gets separated into individual components, depending upon its affinity with the stationary phase and the mobile carrier gas phase, and 3) the detector, where the …

What is GC ECD?

Gas Chromatography – Electron Capture Detector or GC-ECD is a technique used to analyse halogenated compounds and is primarily used in the environmental, forensic and pharmaceutical markets.

How does a GC-MS work?

The GC works on the principle that a mixture will separate into individual substances when heated. The heated gases are carried through a column with an inert gas (such as helium). As the separated substances emerge from the column opening, they flow into the MS.

Is GC-MS expensive?

The cost per sample is also based upon the number of samples to be analyzed. As a rough approximation metals analyses usually run between $25 and $75 per sample, and LC/MS/MS and GC/MS/MS analyses are typically between $100 and $200 per sample.

What is an advantage of GC-MS?

One of the major advantages of GC-MS compared to LC-MS is the high reproducibility of generated mass spectra using EI. The electron impact ionization process, used in GC-MS, is a hard ionization that results in the production of very reproducible mass spectra from one instrument to another.

What is the difference between GC and GC-MS?

GC is used for analyzing volatile organics, and generally separating by boiling points. GCMS indicates that a mass spectrometer is used as the detector for the GC. When a mass spectrometer is used as a detector, you have LCMS.

How do you do GC-MS?

1) Inject sample into Gas Chromatograph (GC) – The sample is injected into a port which is heated to up to 300° C where the material is then volatilized. 2) Separation of gaseous components as they flow through the column – The column is wound within a special oven which controls temperatures from -20° to 320°.

What are at least four major sections of a GC?

A typical gas chromatograph consists of an injection port, a column, carrier gas flow control equipment, ovens and heaters for maintaining temperatures of the injection port and the column, an integrator chart recorder and a detector.

Why choose Agilent GC/MS instruments?
