AS-2500 Autosampler

Increase the range of samples amenable to analysis by GC or GC/MS using the AS-2500 Pyroprobe Autosampler. The AS-2500 provides hands-free analysis of up to 36 samples. Solid, viscous liquid and powder samples are analyzed directly, eliminating the need to perform lengthy sample extractions or derivatizations. A patented heating method provides the flexibility to perform both high performance thermal desorption and pyrolysis on the same sample. Microsoft Windows compatible software facilitates methods development and allows for standard operating procedures to be written for GLP/GMP compliance.

Applications:

Previously in-extractable materials such as natural and synthetic polymers, paints, laminates, fuels, packaging materials, rubber, surfactants, textile materials, inks, and adhesive tapes can now be analyzed with a GC or GC/MS thanks to the AS-2500 Autosampler. Designed with high precision and state-of-the-art electronic control, the AS-2500 heats semivolatile and nonvolatile materials at operator definable temperatures up to 1300°C with heating rates up to 20,000°C per/sec. Flexibility of control of the heating rates, start and finish temperatures and hold times permit both thermal desorption, headspace and pyrolysis experiments to be performed as required. Direct analysis saves time and valuable research funds by eliminating solvent extraction and sample derivations. Furthermore, quality control and methods development applications benefit from the high level of reproducibility of the Autosampler allowing decisions to be made quickly based upon relative area ratios of peaks in the sample chromatogram.

The AS-2500 Autosampler can be operated in either the manual single sample mode or the automated mode with 36-position sample tray as standard. An optional tray, which provides up to 45 samples further enhances operational capacity allowing unattended operation over a weekend or holiday period. Standard temperature controls include multi-ramp capability from ambient to 1300°C with ramp rates from 20°C per millisecond to 0.01°C per minute. Independent control of the Autosampler interface temperature up to 300°C and a programmable clean heating function ensure that background contamination is not a problem. Short sample path lengths between the pyrolysis chamber and the GC injector ensures that chromatographic resolution is maintained. The CDS 2000 PLUS optional software package provides an easy to use means of programming the Autosampler for consistent maximum performance. Simple screen menus allow entry and storage of methods as well as graphical representations of the methods.
