Types of Autosamplers
An autosampler is a sampling device that periodically provides samples to an analytical instrument. It is typically coupled with a laboratory instrument and is used to collect samples from a large source of sample. The following article will discuss three common types of autosamplers: split samplers, carousel samplers, and pushed loop samplers. Understanding which type of autosampler to choose is important for your research.
GC autosamplers

HTA has introduced two new GC autosampler models, the HT3000A and HT3100A, which offer the highest sample capacity and a host of advanced features. These autosamplers also boast touch-screen displays to streamline instrument control. Both models offer automation of up to 15 samples, making them ideal for laboratories running small batches. In addition to high performance, HTA GC autosamplers are also compatible with a large variety of GCs and GC-MS instruments.

The HT2800 provides one-touch operation, allowing users to enter the range of vials and press the START button. The full-color touch-screen interface offers greater usability and accessibility. The HT2800 enables users to switch between modalities and GCs in less than five minutes. Additionally, it allows users to switch from splitless to split injection modes without having to switch between applications.
GC split samplers

A GC split sampler is an automatic device that loads a sorbent into a cartridge and then elutes the analyte of interest. These sample preparation steps may involve a packing compound or an inorganic material. The packing compound helps increase the volatility and polarity of a sample and enhances the separation of groups of compounds on the GC column. Sample preparation time can be reduced significantly by using a GC split sampler.

The TriPlus 500 HS GC split sampler features an innovative design, which minimizes syringe handling time while maintaining the dual-loop injection capability. The TriPlus 500 HS autosampler also boasts expanded vial capacity and high-speed throughput, resulting in improved productivity for routine laboratories. The TriPlus 500 HS has three levels of agitation to minimize the overall cycle time, and its high extraction efficiency helps reduce chromatography analysis time.
GC carousel samplers

GC carousel samplers are commonly used in gas chromatography (GC). This type of chromatography device contains first and second transfer towers, associated syringe actuators, and a carousel tray that rotates. The sampler can be automated or manual. autosampler There are two rows of samplers. The first row is mounted on the carrier and includes a carousel tray containing the sample and the second row is mounted between the first row and the rotation axis of the carousel tray.

Headspace autosamplers differ from those used in liquid chromatography. The latter is more complex than liquid autosamplers and includes a much wider range of options. Nevertheless, a chromatographer should be aware of the differences in these autosamplers and the advantages and disadvantages of each type. To understand which autosampler is best suited for their needs, read on.
GC pushed-loop samplers

GC pushed-loop sampler systems are the most common types of GC analytical instruments. These instruments can be configured to use either a liquid or a gaseous acceptor phase. The former can use a polymeric hollow fibre and an internal standard. Analytes are entrapped on the polymer sorbent and desorb by means of an organic solvent. The organic phase is then injected into the GC instrument via a LVI.

As the name implies, a GC pushed-loop sampler is a device that pushes an organic solvent through the loop and analyzes it. The device is automated and manufactured by Gerstel. This type of GC sampler is best for high-throughput chemistry. The samplers typically hold one to five milliliters of organic solvent. During the analysis, the aliquot of the organic solvent is separated.
