Pressure System for Liquid Chromatography

A pressure system for liquid chromatography comprises:

• (FIG. 1)
• a fluid pressure medium supply;
• a first plurality of fluid transfer pipes;
• a first plurality of flow limiters;
• a source pressure control unit;
• an output of the fluid pressure medium supply being connected to each of the first plurality of fluid transfer pipes, wherein the fluid pressure medium supply is configured to drive fluid pressure medium through the output of the fluid pressure medium supply toward the first plurality of fluid transfer pipes along a pressure output path;
• each of the first plurality of flow limiters being interconnected with one of the first plurality of fluid transfer pipes, wherein each of the first plurality of flow limiters allows a specified flow rate of fluid through one of the first plurality of fluid transfer pipes;
• and
• the source pressure control unit being configured to regulate the pressure of fluid pressure medium being delivered to the first plurality of fluid transfer pipes from the fluid pressure medium supply.
