Technology Description: | |
The ACEM 900 provides a base system, with add-on modular components, to combine sample adsorption and thermal desorption techniques with gas chromatography to do air monitoring, on-line or off-line, with automated calibration, of a single source, multiple sources, or a mixture of sample types at the parts per billion or sub-PPB level. With its function capability, the ACEM system can serve as a continuous monitor, or thermally desorb single sorbent tubes. Linked with an Interface Module, the ACEM can accept samples from a vacuum pump, pressurized canister or bottled standards, or be coupled with a purge and trap instrument for water analysis. With the addition of a Multiple Thermal Desorption Unit, the ACEM can process 8 to 16 sorbent tubes unattended.
The system may be utilized with all sizes of capillary columns, .2-.75mm ID, without cryofocusing, due to a patented sequential trapping design. Samples are collected on high capacity sorbent tubes designed to retain a wide array of compounds from large sampling volumes. Samples are then transferred to a narrow-bore capillary tube packed with similar adsorbent material, from which they are desorbed into the capillary column in a narrow-band, high efficiency injection without cyrogenic cooling of the GC oven or column.
