Tetrodotoxin (TTX), a powerful sodium channel blocker, usually exists as a mixture of its analogs (TTXs) in natural sources. Due to the structural variation, some analogs are difficult to detect using the postcolumn liquid chromatography-fluorescent detection (LC-FLD) system.

Protein Sequencing with Tandem Mass Spectrometry
2009The recent introduction of electrospray ionization techniques that are suitable for peptides and whole proteins has allowed for the design of mass spectrometric protocols that provide accurate sequence information for proteins. The advantages gained by these approaches over traditional Edman Degradation sequencing include faster analysis and femtomole,

Tandem mass spectrometer and tandem mass spectrometry method
2011The spectrometer has a mass analyzer comprising an ions trap (2) to receive ions from an ionization source (1) and a detecting unit to detect ions leaving the trap based on relative load mass of ions. An ions activation unit activates a part of the trapped ions. A luminescent gas-discharge lamp (4) of the activation unit generates a light beam directed

Tandem Mass Spectrometry in Hormone Measurement
2013Mass spectrometry methods have the potential to measure different hormones during the same analysis and have improved specificity and a wide analytical range compared with many immunoassay methods. Increasingly in clinical laboratories liquid chromatography-tandem mass spectrometry (LC-MS/MS) assays are replacing immunoassays for the routine ...
