Ancillary Procedures

Ancillary procedures to start and monitor therapy (e.g., preliminary and follow-up laboratory tests)... 

The earlyidentification ofthe clinical andMR patterns of acute territorial infarcts can help the managing physician concerning prediction of outcome, risk of early death and dependency, risk of recurrence, stroke mechanism and etiology, selection of ancillary procedures, selection of best (effective and safe) anti-thrombotic treatment, risk of complications, length of stay and cost of hospital care. 

In order to obtain a more precise evaluation of the presence and nature of eye injury iu ocular irritation tests, the following ancillary procedures have been used. 

Earlier, the need for a master batch record document was discussed. This document describes the manufacturing instructions necessary to consistently produce batches of APIs that meet predetermined specifications. There will also be ancillary procedures, which wiU define all the conditions and their control parameters necessary to assime consistency from batch to batch. Isolated materials should be labeled at each step in the process. This is true not only for the raw materials but also as in-process materials are generated and isolated, the material s name, lot niunber, and its status should be clearly labeled. As stated earlier, major pieces of equipment should be clearly labeled with a unique identification number and its status (cleaned and ready to be used, to be cleaned, or in use). If a processing step is determined to be a critical processing step, it may require witnessing of its completion by a second person, with the witnessing docmnented on the batch record. 

Laboratory procedures must be documented and readily accessible in the QAP manual. Individual procedures must be available for review when resolving an analytical problem, and the entire file for auditing laboratory operation. The file should contain all currently applied radioanalytical chemistry and instrumental procedures, variants of procedures (e.g., for special matrices or contaminants), and ancillary procedures (e.g., for reagent preparation, calibration, and QC). Each procedure and procedural change should be signed and dated. The QA officer is responsible for assuring that actual laboratory operation is reflected exactly in the manual. Periodic updating is necessary to formalize as revisions the insertions, deletions, and additions that can be expected to accumulate in the analyst s or operator s copy of a procedure. 

Total enclosure may be in the form of a room with grilles to facilitate air flow this functions as a hood and operates under a slight negative pressure with controls located externally. Entry is restricted and usually entails use of comprehensive personal protective equipment. Ancillary requirements may include air filters/scmbbers, atmospheric monitoring, decontamination procedures and a permit-to-work system (see page 417). 

For reasons discussed above, we needed a complementary, ancillary tool for comparison of the mass spectra of components from multiple urine samples. We desired that the procedure have several characteristics (1) requires little if any manual data entry by the operator (2) utilizes data automatically generated by ChemStation and organized into Microsoft Excel spreadsheets (3) displays both retention times and mass spectral data in the same window (4) minimizes subjective operator judgments and (5) is simple and rapid to use. What emerged after several iterative improvements are the FindPeak macros discussed below. These are largely due to the expertise of Y. Aubut, with valuable input from J. Eggert. 

A number of ancillary issues must also be addressed in addition to those dealt with in the compound selection procedure itself. One of these is compound attrition each year, about 1% of the compounds in a given collection are, for a variety of reasons, no longer available. Some of these maybe rare or unusual compounds that are difficult to replace. If and how these are replaced is a subject for discussion that will not, however, be dealt... 

Installation Qualification After equipment selection, it is necessary to assure that the equipment is installed well. The IQ document describes and validates the procedure of the equipment installation. It establishes confidence that the process equipment and ancillary systems are capable of consistently operating within established limits and tolerances [10]. The equipment manufacturer and pharmaceutical company must agree and check the IQ, which must be approved by the pharmaceutical company at the end. This document certifies that equipment was installed as specified by the manufacturer and the purchaser. 

Current practices in analytical SFE are organized into off-line and on-line procedures, despite their common physicochemical basis. Off-line SFE, the current method in fashion, offers more flexibility with respect to extracting different sample sizes and types, as well as in the choice of the final analytical method. On-line procedures are usually combinations of SFE with ancillary techniques such as GC, LC, supercritical fluid, or gel permeation chromatography. 

Tuned output control signals to peripheral and ancillary devices such as sample valves, column switching valves, and other external functions which are part of the automated procedure.
