LC-MS (Liquid Chromatography-Mass Spectrometry) is a highly powerful analytical technique that combines the exceptional separation power of liquid chromatography with mass spectrometry, a very sensitive chemical identification technique. LC-MS can be used to determine the constituents of complex che...
How important is the purity of the nitrogen used for LC-MS separations? What control do researchers have over this?
In LC-MS, most applications recommend 95% pure nitrogen because oxygen, which makes up the remaining 5% of the gas, has not been found to be detrimental toanalysis when supplied...
