A system comprising an autosampler, a liquid chromatography apparatus, an electronic memory storage device electronically coupled to both the autosampler and the LC apparatus, a data line electrically coupled between the autosampler and the LC apparatus, an autosampler control process and an independently operating LC control process, the autosampler control process and independently operating LC control process being implemented within a computer system or other controller system that is electronically coupled to both the autosampler and to the LC apparatus, wherein the LC control process is operable to cause the LC apparatus to chromatographically separate components of a sample in accordance with one or more LC analysis procedures and to transmit a signal to the autosampler control process upon completion of each LC analysis procedure, wherein the autosampler control process is operable to cause the autosampler to delay operations for a delay time, Δ t d, after receipt of the signal, withdraw a portion of a first sample from a container, prepare the portion of the first sample for injection into the LC apparatus, transport the portion of the first sample to the LC apparatus and inject the portion of the first sample into the LC apparatus in accordance with the one or more LC analysis procedures, the system CHARACTERIZED IN THAT the autosampler control process is operable to: read, from a database stored on the electronic memory storage device, a stored value of a pre-injection time, t r1 max, that is required for the autosampler to perform operations preparatory to injecting the portion of the first sample into the LC apparatus for analysis by a first LC analysis procedure, wherein the database includes a plurality of stored pre-injection time values, t r1 max, t r2 max, t r3 max,... that correspond to respective different LC analysis procedures; calculate the autosampler delay time, Δ t d, from the stored pre-injection time value, t r1 max, and a time, t s2, required to perform LC analysis of a second sample; cause the autosampler to perform the autosampler operations preparatory to injecting the portion of the first sample into the LC apparatus after delaying said autosampler operations for a time corresponding to the autosampler delay time, Δ t d; and if no autosampler or LC-apparatus errors or malfunctions have been encountered during the performing of said autosampler operations, cause the autosampler to inject the portion of the first sample from the autosampler into the LC apparatus after receipt of the signal from the LC apparatus. read, from a database stored on the electronic memory storage device, a stored value of a pre-injection time, t r1 max, that is required for the autosampler to perform operations preparatory to injecting the portion of the first sample into the LC apparatus for analysis by a first LC analysis procedure, wherein the database includes a plurality of stored pre-injection time values, t r1 max, t r2 max, t r3 max,... that correspond to respective different LC analysis procedures; calculate the autosampler delay time, Δ t d, from the stored pre-injection time value, t r1 max, and a time, t s2, required to perform LC analysis of a second sample; cause the autosampler to perform the autosampler operations preparatory to injecting the portion of the first sample into the LC apparatus after delaying said autosampler operations for a time corresponding to the autosampler delay time, Δ t d; and if no autosampler or LC-apparatus errors or malfunctions have been encountered during the performing of said autosampler operations, cause the autosampler to inject the portion of the first sample from the autosampler into the LC apparatus after receipt of the signal from the LC apparatus.
