Zero Blank AutosamplerZero Blank Autosampler

The “Zero Blank” autosampler developed by Costech, uses a “sealed carousel” design. All samples are purged simultaneously with helium in an enclosed chamber. This eliminates any nitrogen background (from atmosphere) which is introduced in the open carousel sampler when it moves to drop the sample into the reactor.

Our 150 position pneumatic autosampler has carousels (three) which are open to atmosphere, and samples can be added continuously while running. The sample holes in the carousels are 11.5 mm in diameter and can accommodate samples like glass fiber filters or large, bulky samples. Alarge viewing port allows you to clearly see the sample combustion during the analysis.
