Connecting the Low-Pressure Solvent Lines
You need to connect the low-pressure solvent lines to the Surveyor MS Pump Plus before you
operate the pump. There are four low-pressure lines that bring the four solvents to the pump.
Solvents should always be HPLC quality and free of particulate matter. Because the Surveyor
MS Pump Plus contains very small, precision-machined parts, it can easily be affected by
small particles entering the pump. Aqueous eluents are particularly susceptible to bacterial
growth that can cause numerous problems.
To prevent bacteria and/or particulate matter from entering the pump, do the following:
• Filter all solvents thoroughly.
• Discard aqueous mobile phases on a daily basis or add a bactericide such as sodium azide
to inhibit bacterial growth (0.65 g/l NaN

prevents growth of most kinds of bacteria).

CAUTION
Sodium azide is highly toxic and carcinogenic. Take care when disposing of
solutions that contain sodium azide because azides can react with heavy metals to form
explosive compounds.
