A New Cryogenless TO15 Canister Preconcentrator with Reduced System Carry-Over When Exposed to Higher Concentration Samples
Overview A new preconcentrator design is presented which eliminates the need for liquid nitrogen or complicated electronic cooling while performing US EPA Method TO15 analysis. A new technology called Multi-Capillary Column Trapping System (patent pending), or MCCTS, is used to concentrate all TO15 compounds at 35°C, which is achieved simply by using cooling fans. Two […]
