Description:
ISQ EM single quadrupole mass spectrometer for liquid chromatography with extended mass range, HESI source

Adding mass spectrometry (MS) to your liquid chromatography (LC) analyses gives you access to the valuable data that only MS can provide. The new, easy-to-use ISQ™ EM Single Quadrupole Mass Spectrometer seamlessly integrates with LC systems for reliable, robust, and easy LC-MS routine analysis with an extended mass range for more flexibility. Detect and quantify a variety of analytes by choosing to use either heated electrospray ionization (HESI) or atmospheric pressure chemical ionization (APCI). Integrated software allows both novices and experts to quickly master MS to gain more insights from every sample.
