Title: PORTABLE GAS ANALYSIS DEVICE WITH COMPACT MEASUREMENT DEVICE
Abstract:
The invention relates to a portable gas analysis device, in particular for highly volatile compounds, having a separating column (3) and a detector (8). The separating column is composed as a multi-capillary unit (3) from parallel individual capillaries and, depending on the length, is bent into a compact shape, preferably even wound into multiple turns. A thermally conductive casing (5) and a thermal stabilising device (56) are provided for the multi-capillary unit. The thermal stabilising device (56) comprises a temperature sensor (52), a heating element (53) and control electronics (58). The casing (5) protects the sensitive multi-capillary unit (3) from mechanical actions; it acts as a protective space. The temperature-controlled casing (5) also forms a space in which uniform and controlled conditions prevail and which in particular is isolated from the temperature and humidity of the environment, allowing reliable measurements outside a laboratory environment, in the field. This double effect of the casing (5) for the capillaries in conjunction with the compact dimensions forms the true essence of the invention.
