Appeal No. 2004-1137
Application No. 09/734506
CLAIMS
1. A sampler for dispensing and cooling a sample of a fluid
withdrawn at a sampling location, said sample to be stored at a
selectable storage temperature, said fluid having an
instantaneous sampling temperature greater than the storage
temperature, said sampler comprising:
a vessel assembly of a predetermined volume, said vessel
assembly including a tubular intake vessel for conducting the
withdrawn fluid and a storage vessel for storing the fluid
sample; and
a cooling assembly thermally coupled to the vessel, said
cooling assembly including a first cooling volume being operable
to cool the fluid sample to the storage temperature, and a second
cooling volume being operable to cool the withdrawn fluid to a
temperature below the sampling temperature;
wherein at least the storage vessel is disposed in said
first cooling volume, and wherein the vessel assembly is disposed
in said second cooling volume at least in sections.
17. A method of dispensing and cooling a sample of a fluid
withdrawn at a sampling location by means of a sampler, said
sample to be stored at a selectable storage temperature value,
said fluid having a sampling temperature value greater than the
storage temperature value, said sampler comprising a vessel
assembly of a predetermined volume with a tubular intake vessel
for conducting the withdrawn fluid, said sampler further
comprising a storage vessel for storing the fluid sample, said
vessel assembly having an internal temperature, wherein prior to
the dispensing said internal temperature of the vessel assembly
having an initial internal temperature value being lower than the
sampling temperature value; and said sampler further comprising a
cooling assembly thermally coupled to the vessel assembly for
adjusting said internal temperature of the vessel assembly, said
cooling assembly comprising at least a first cooling volume
having a first cooling temperature, said cooling temperature
being set at the storage temperature value at least after the
storing of the fluid sample, said method comprising steps of:
