The LCMS-9030 incorporates the patented ultrafast technologies used in Shimadzu LC-MS/MS platforms to deliver outstanding speed. Innovative TOF architecture enables precise, ultra-fast pulsing of ions into the flight tube and ideal reflection back to the detector.

Tekniken tillämpades för att Masspektrometri, ofta förkortat som MS, är en teknik för att separera joner i gasfas från varandra utifrån deras förhållande mellan massa och laddning (m/z). QTOF Mass Spectrometry Since its first commercial launch 25 years ago, quadrupole time-of-flight (QTOF) mass spectrometry (MS) has revolutionized numerous fields, ranging from biological and pharmaceutical research to clinical toxicology. The 6530 Q-TOF LC/MS delivers the power of accurate-mass mass spectrometry, so you can be fully confident of your data. All software workflows from our high-end and mid-range instruments are fully compatible with the 6530, giving you the most powerful access to your data and research possible. The Agilent 6545 LC/Q-TOF is the standard for mid-range quadrupole time-of-flight LC/MS performance. Designed for untargeted sample analysis, it enables broad screening, comprehensive profiling, and identification of unknowns. The 6545 LC/Q-TOF MS delivers sensitivity, resolution, mass accuracy, isotopic fidelity, and speed in one measurement.

QTOF Mass Spectrometry. Since its first commercial launch 25 years ago, quadrupole time-of-flight (QTOF) mass spectrometry (MS) has revolutionized numerous fields, ranging from biological and pharmaceutical research to clinical toxicology. The unique hybridization of quadrupole and TOF technology resulted in high-resolution, high mass accuracy Tandem mass spectrometry, also known as MS/MS or MS 2, is a technique in instrumental analysis where two or more mass analyzers are coupled together using an additional reaction step to increase their abilities to analyse chemical samples.
