Autosamplereita

Autosamplereita, often referred to as autosamplers, are automated laboratory devices designed to introduce liquid samples into analytical instruments. These instruments can include chromatographic systems like High-Performance Liquid Chromatography (HPLC) and Gas Chromatography (GC), as well as mass spectrometers and atomic absorption spectrometers. The primary function of an autosampler is to perform sample preparation and injection tasks repetitively and with high precision, thereby increasing laboratory throughput and reducing the potential for human error.

Autosamplers typically consist of a robotic arm, a carousel or tray to hold sample vials, and a syringe or pump mechanism for aspiration and dispensing of the liquid. They are programmed with specific parameters, such as the number of samples, injection volume, rinse cycles, and the order of analysis. This automation allows for unattended operation, enabling laboratories to process a large number of samples overnight or during periods of low staffing.

Modern autosamplers offer advanced features, including the ability to perform in-line sample preparation techniques such as dilution, derivatization, and internal standard addition. They are also equipped with various detection systems to ensure sample integrity and monitor the injection process. The use of autosamplers is crucial in fields like pharmaceuticals, environmental testing, food safety, and clinical diagnostics where consistent and high-volume sample analysis is required.
