A drop of sample liquid or sample liquid is selectively filtered under reduced pressure, the use of a vacuum drying apparatus and the apparatus

摘要

Filtered selectively in vacuo liquid sample (28) in the compartment comprising the inlet and outlet openings (57) [Abstract]-carriers (26), region (32) outlet opening (28) said compartment It is provided a chamber (24) to an apparatus for vacuum drying drops of the sample liquid present in the. The chamber may be a carrier or lid (84) (26), placed in airtight substantially being directed in (46) interior space (24) the chamber (32) and its outlet opening closed I include (48) having an opening (52) opening edge. One of the side walls, are formed as (44) access sidewalls can be hermetically sealed and substantially open, to introduce into (46) in the interior space (24) the chamber (26) carrier. In addition, and a 82 vacuum pump attached to the (81) inlet conduit terminates in (46) in the interior space (24) chamber, the vacuum pump (82) carrier The apparatus (26) die for withdrawing a liquid sample outlet opening (28) from (32) compartment when it is located opening edge the top wall (40) to (50) is closed (44) Access the sidewall (24) and chamber generates one low pressure, carrier (26) is arranged inside the space chamber (24) to (46) in which is arranged an opening edge the top wall (40) to (50) (84) cover, and chamber ( while the access side wall 24) (44) is closed, to generate a second low pressure higher than the first low pressure for drying drops of liquid samples still present outlet opening (28) to (32) compartments it is intended for.
