| description | A sampling unit, especially for stratospheric air sampling when carried aloft by balloon or another vehicle, comprises a liquid coolant reservoir within an evacuated vessel and provided with a cryogenically cooled adsorber for maintaining the vacuum. Nozzles in the vessel wall can be selectively opened and closed to allow samples to be drawn over cooled fingers on which components of the sample are frozen or sublimed. A vacuum gate can be connected to the device for removal of the cold fingers for transfer to a spectrometer. |
