Preconcentrating a sample |
| abstract |
A chemical analysis system is disclosed wherein, in evacuating a preconcentrator housing (2) prior to desorption, a pump system (13) reduces an internal pressure of the preconcentrator housing to a level substantially equal to an internal pressure of a chemical analyzer such that flow restrictors and/or membranes (15) between the chemical analyzer (7) and the preconcentrator housing (2) may be omitted. The chemical analysis system includes a chemical analyzer (7), a preconcentrator housing (2) coupled to the chemical analyzer, the preconcentrator housing enclosing a temperature control element (5, 18) and a sorbent material (1), the temperature control element configured to heat the sorbent material to adsorb or desorb a chemical of interest; and a pump system (13) coupled to the preconcentrator housing and the chemical analyzer, the pump system configured to evacuate the preconcentrator housing prior to desorption of the chemical of interest. |
