1. An automated device that collects and injects samples into an analytical instrument, such as a chromatograph or mass spectrometer, without manual intervention.
Usage: technical; used in chemistry and laboratory settings

Examples

• The autosampler can process dozens of samples overnight without operator supervision.
• Modern liquid chromatography systems are equipped with autosamplers to improve throughput and reduce human error.
• The autosampler's carousel holds up to 100 vials for sequential analysis.
• Researchers use the autosampler to maintain consistent injection volumes across all samples.
• The autosampler reduced analysis time by automating the sample preparation workflow.
