Focus on Analyzers

Space-saving autoinjector/autosampler for GC

The AOC-30 Series autoinjector/autosampler (photo) is designed to enable gas chromatography (GC) users to produce high-quality results with less downtime. The AOC-30 automatic sample-injection system automates analysis, reduces an operator’s workload, and enables continuous analysis with a high degree of accuracy that cannot be achieved by manual operation. The structure of the company’s Xtra Life inlet septa results in excellent injection durability and enables continuous analysis that is approximately ten times that of conventional systems — up to 1,000 injections before replacement, says the company. Advanced sample-washing functionality provides continuous analysis without the worry of running out of solvent. Four 4-mL vials can be used in a single tower, and twelve 4 mL-vials can be used with the full tower and sampler system. Users can customize cleaning solvent types and cleaning sequences to optimize the cleaning effect for each analysis. The single-tower system provides automated analysis of up to 30 samples, covering a wide range of analysis needs. Another sample tower or samplers can be added to increase analysis capacity and flexibility. — Shimadzu Scientific Instruments Inc., Columbia, Md.
