Coordination of solvent delivery with pre-injection operations in a liquid chromatograph
A liquid chromatography system includes an autosampler that prepares a sample for introduction to a solvent stream and a solvent delivery system that delivers a solvent stream to the autosampler. Delivery of the solvent stream occurs in parallel with the autosampler's pre-injection operations. The autosampler starts pre-injection operations to make the sample ready for injection into the mixture stream, and the solvent delivery system starts delivery of a solvent stream to the autosampler. The start of the solvent stream delivery is coordinated with the start of the pre-injection operations such that the solvent stream arrives at the autosampler approximately coincident with when the autosampler completes the pre-injection operations, making the sample ready for injection.
