Abstract
Methods of chromatographic detection are provided that include the step of providing a chromatography instrument without an autosampler, an external device, a pressurized sample injection device and a chromatographic data system. The chromatographic instrument has a sample valve, a column manager and a solvent manager. The present methods further include the steps: injecting sample into the sample valve with a pressurized sample injection device; transmitting a signal from the chromatographic data system to the external device, receiving the signal by the external device, producing an event output with the external device, discharging solvent from the solvent manager into the sample valve, and discharging sample into the column for chromatographic detection.
