The liquid chromatography system described herein includes both high pressure liquid chromatography (HPLC) as well as high pressure capillary liquid chromatography (CapLC).

A fluid pressure reduction valve comprises an inlet (2) for high pressure fluid and an outlet (3) for low pressure fluid.

A control valve for injectors, in particular for common rail injectors of internal combustion engines acts as a metering device for a high-pressure liquid, especially fuel and is located in an injector body comprising a high-pressure liquid inlet.

The nozzles (24) are connected to a high pressure liquid supply system which allows a constant supply of liquid of the correct pressure.

A flow path switching valve (1) into which a high-pressure liquid and a low-pressure liquid flow.

An energy-efficient method of recovering carbon dioxide (CO2) in a high-pressure liquid state from a high-pressure gas stream.

The liquid refrigerant may be sourced from high pressure liquid refrigerant from the condenser section.

The method and apparatus do not require the use of high-pressure liquid chromatography.

The invention also discloses high pressure liquid chromatography methods for analysis of daptomycin purity.

The present invention relates to a method for burring metal parts using a high-pressure stream of liquid which is ejected from a high-pressure nozzle and is directed towards the part to be burred.

More particularly, this invention concerns the use of high pressure jets of liquid to remove such concrete scale.

At this point, the refrigerant is in the form of a high pressure/high temperature liquid.

An inlet throttle (18), which is hydraulically connected to the high-pressure liquid inlet, leads laterally into the control chamber (15).

2 At the condenser, the high temperature, high pressure gas releases its heat to the outdoor air and becomes subcooled high pressure liquid.

The pressure outlets of each basic cell is fluidically connected through a flow restrictor (119) to a high-pressure fluid supply, the pressure outlets providing pressurized fluid for maintaining a fluid-cushion between the object and the platform.
