International Classification:

G01N 15/06
G01N 35/10
G01N 33/18

US Classification:

422 63, 422 67, 422 681, 422500, 422509, 422512, 436 8, 436 43, 436 62, 436146, 436180

Abstract:

An automated standards sampling apparatus () and method for using such, apparatus are described. The apparatus can be integrated with a liquid analyzer to form a compact, integrated liquid analysis unit. When used in combination with a specially adapted vial se of standard liquids, the apparatus provides a system for automated, substantially error-free periodic calibration and accuracy verification for an online TOC analyzer (). The automated standards sampling apparatus of this invention facilitates the easy introduction of known concentrations of standard solutions and “grab” samples into online TOC analyzers to satisfy regulatory compliance, calibration, and validation requirements. The automated standards sampling apparatus of this invention also provides substantially improved reliability, higher productivity and better performance when running the critical and regulatory driven System Suitability Test than does any conventional sampling equipment, and it is likely to find wide use in a variety of industrial applications other than its principal intended use in the pharmaceutical industry.

General Electric Company - Schenectady NY

International Classification:

B01F 13/08

US Classification:

366274

Abstract:

The stirring apparatus is an electronic design that generates rotating magnetic fields to drive magnetic stir bars within vials placed above the cover of the stirring apparatus. Below the cover is a magnetics board containing multiple vial groups of four air core coils arranged in rectangular patterns. Each vial group has with two pairs of diagonal coils. The coils in each pair are wired in series and have opposite winding directions. Each pair is driven by a different phase of a stepper motor driver. The vial groups are spaced appropriately for placing one vial above each group. The adjacent coils of adjacent vial groups are driven by the same phase and have the same magnetic direction. The cover contains an array of pole standoffs that matches the coil pattern. The hollow center of each air core coil contains at least a portion of one pole standoff.
