There are several ways to find the serial number for your SCIEX mass spectrometer and its LC components. The easiest way is to locate the file information associated with a data file acquired on the LCMS system of interest. In Analyst® software, open the data file, and then choose the Explore menu in the horizontal bar. Select Show, and then Show File Information.
The serial number can also be located by checking the back or the side of the mass spectrometer. (The location of the serial number depends on your instrument’s model number; “blue” boxes will have the serial number located on the side of the instrument, and for older models, the SN is found on the back of the instrument.)
