Abstract
Apparatus for withdrawing liquid samples from liquid/solids media, e.g., phosphoric acid slurries, for the downstream analysis thereof, is comprised of (i) means adapted for insertion into a liquid/solids medium to selectively separate and receive a liquid fraction therefrom, (ii) a liquid storage first chamber in communicating relationship with said separating and receiving means (i), (iii) a liquid sample receiving second chamber in independent, parallel communicating relationship with said separating and receiving means (i) and which comprises means for exteriorly discharging sample contained therein, and (iv) means permitting the filling or emptying of said second chamber (iii) independently of said first chamber (ii).
Claims20
An apparatus for withdrawing a liquid sample from a particulate solid containing liquid medium, comprising:
- a collection assembly constructed and arranged for insertion into a particulate solid containing liquid medium, and comprising means for filtering a liquid fraction from such a medium and collection chamber means for receiving a liquid fraction filtered by said filtering means;
- first chamber means for receiving liquid;
- first means for communicating said first chamber means with said collection chamber means;
- second chamber means for receiving sample liquid;
- second means for communicating said second chamber means with said collection chamber means, said first and second communicating menas separate of each other so that said first and second chamber means are in parallel flow relationship to each other, said first and second communicating means including separate orifices independently open to said collection chamber means;
- first means for selectively drawing liquid fraction from said collection chamber into said first chamber means through said first communicating means;
- second means for selectively drawing liquid fraction from said collection chamber into said second chamber means through said second communicating means, said first and second selectively drawing means operable independently of each other so that liquid fraction may be first drawn into said first chamber means without liquid fraction being drawn into said second chamber means;
- first means for selectively discharging drawn liquid from said first chamber means;
- and
- second means for seIectively discharging drawn sample liquid from said second chamber means.
