What is a syringe pump and its use?

A syringe pump is a mechanical device that uses a plunger to extract a liquid from one location and move it to another, such as for the application of mass spectrometry. In the laboratory, syringe pumps are used to distribute precisely measured liquids into scientific instruments for experimentation and production.

What are the common problems with syringe pumps?

Because syringe pumps have moving parts, those parts can wear out over time. Many are computer driven, and user error or software problems can occur.
