An autosampler works by aspirating and injecting a precise sample volume into the mobile phase stream. Using an autosampler reduces manual labor and improves injection precision and accuracy compared to manual sample injection, an absolute priority for a …

2019年8月1日 · Autosampler: A device that automates the introduction of an aliquot of sample solution to the HPLC column. An HPLC autosampler typically comprises a sample storage compartment with an injector, consisting of a valve, a sample dosing or metering device, and a moving sampling needle.

2025年1月30日 · The total-volume injection SIL-30AC autosampler features a pressure tolerance of 130 MPa as well as the world’s fastest sample injection (10 seconds), which dramatically reduces the total cycle time. It includes auto pretreatment and overlapping functions as standard, and an optional loop-injection method configuration to minimize delay volume.

HPLC高效液相色谱自动进样器有两种主要工作原理：推入式/吸入式装液和分流环。 在推入式和吸入式装液自动进样器中，通过用进样针推动（推入式装液）或抽吸（吸入式装液）将样本输送到样本定量环中。

Innovative and carefully designed Thermo Scientific autosamplers and sampler extension module ensure reliable, precise and accurate injection for nanoliter to milliliter sample volumes. They support a wide range of formats and sample throughputs. Choose from rapid separation, nano, capillary, micro, standard, and more.

In HPLC, an autosampler is a device automatically injecting samples from vials into the chromatography system. It picks up a precise volume of sample using a syringe, delivers it to …

Agilent autosamplers, such as the 1260 Infinity II Vialsampler and the 1260 Infinity II Multisampler, offer the possibility to use an injector program with the ability to define a series of operations that the autosampler carries out sequentially.

2023年1月20日 · HPLC autosamplers greatly improve the precision and throughput of HPLC processes, and these modules have grown more advanced over the years, with capabilities for temperature control, sample dilution, overlapping injections for faster cycle times, and compatibility with ultrahigh-performance liquid chromatography (UHPLC).

2024年8月22日 · Increased Efficiency and Reduced Analysis Time: The autosampler significantly improves workflow efficiency and shortens the overall analysis time. Enhanced Precision and Throughput: It greatly enhances the precision and throughput of HPLC analysis.

What is an HPLC autosampler, and how does it work? a. An HPLC autosampler is a device used in liquid chromatography to automate the process of injecting precise volumes of liquid samples into the HPLC system. It works by drawing the sample from vials or plates and injecting it consistently into the system for analysis. q.
