GC, or gas chromatography, autosamplers are instruments that automatically take a sample and insert it into the GC for analysis, which is both more time effective and more reliable than doing it by hand. GC autosamplers can be used anywhere GC is used, including forensic, environmental, and medical labs, in the pharmaceutical and food and beverage industries, to analyze a sample for quality control, purity, or to look for a particular analyte. There are three main types of GC autosamplers; liquid, which work with liquid samples, headspace, which work with volatile organic samples, and SPME which uses a fiber to extract the components of your sample. There are GC autosamplers that can do all three types of autosampling.
The types of samples you will be analyzing will dictate which type of autosampler you will need. Keep in mind the sample size you wish to use, how many analyses need to be run in a given time, and if there are different types of samples that would require a multipurpose autosampler.

| Description | Shimadzu’s HS-20 Series of headspace samplers provides a reliable and robust headspace solution for any application analyzing volatile components in a difficult matrix. The HS-20 Series consists of two models: a Loop model for the traditional static headspace methods, and a Trap model, which adds Shimadzu’s HS-20 Series of headspace samplers provides a reliable and robust headspace solution for any application analyzing volatile components in a difficult matrix. The HS-20 Series consists of two models: a Loop model for the traditional static headspace methods, and a Trap model, which adds the dynamic headspace technique for applications requiring greater sensitivity.
The HS-20 Series achieves a new industry standard for repeatability through precise control of gas flow rates, and a mechanism that allows a sample vial to enter the oven from the bottom. This technique minimizes heat loss and thermal instability during the equilibration step. The oven can be heated to 300 °C, enabling accurate analysis of higher-boiling compounds.
Features
- Short, inert sample pathway – minimizes carryover from one sample to the next
- Open-access 90-position sample tray – provides easy access to all vials for loading and enables stress-free maintenance from the top of the instrument
- Accommodates both 10-mL and 20-mL headspace vials within the same sequence without the need for special attachments
- Automated shutdown feature – switches the system to standby at the end of a sequence to save on electricity and carrier gas
- Optional barcode reader records sample ID for reliable traceability

Its proven reliability and reproducibility allows the user to take full advantage of the GC or GC/MS system capabilities. When paired with the AOC-20s autosampler carousel, your laboratory's productivity can be greatly increased. The AOC-20 is highly reliable and capable of high sample throughput, yet it is lightweight and easy to remove when routine injection port maintenance is required. The enhanced needle guide virtually eliminates bent syringe needles. The AOC-20 series can perform the functions of direct liquid injection, on-column injection, ambient headspace and PTV/LVI injection modes. The AOC20 offers precision better than 0.3% and carryover is less than 0.005%. Single or dual tower modes are available.
The AOC-20i is available as a direct replacement for the HP5890’s autoinjector.... Read More |
