How long does LC MS take?
More commonly, analytes require somewhat longer chromatography times for optimal separation. However, even with, by LC-MS/MS standards, long chromatography run times of 10–12 minutes, this leads to a different sample being introduced into the system every 2.5 to 3 minutes.
What is testosterone LC MS MS?
Results for this test will include Free Testosterone and Total Testosterone measured by liquid chromatography and tandem mass spectrometry (LC/MS-MS). Testosterone is the primary male sex hormone. However, it is present in both men and women. In men, testosterone is produced primarily in the testicles.
What is GC MS analysis?
Gas chromatography–mass spectrometry (GC-MS) is an analytical method that combines the features of gas-chromatography and mass spectrometry to identify different substances within a test sample. … Like liquid chromatography–mass spectrometry, it allows analysis and detection even of tiny amounts of a substance.
What is ICP MS and what is it used for?
Inductively coupled plasma mass spectrometry (ICP-MS) is a type of mass spectrometry which is capable of detecting metals and several non-metals at concentrations as low as parts per billion on non-interfered low-background isotopes.
How does the ICP MS work?
For overall performance and economic value, most laboratories choose an ICP-MS with a quadrupole mass spectrometer. A quadrupole works by setting voltages and radio frequencies to allow ions of a given mass-to-charge ratio to remain stable within the rods and pass through to the detector.
