Modes of Storage

The batch record is the only documentation a firm has that can demonstrate that the product was manufactured according to specifications. During regulatory audits, the batch record is a primary document for review, and must be easily and quickly accessible. Most firms have two different modes of storage—recently executed batch record storage and long-term archival. It is recommended that a schedule be established to require that the most recent batch records executed (e.g., the last 6 or 12 months) are readily accessible and any batch records older than this be transferred to a long-term archival location. 

It is notable that in virtually all of these fuel cell bus projects the hydrogen is stored as compressed gas in roof-mounted gas cylinders. This mode of storage has been chosen by virtue of its ready availability and practicality for rapid...

Characterisation of a calibration standard requires information about the concentration of the analyte (preferably to be determined by an independent absolute method), stability of the pure compound and of its solutions, mode of storage (excicator, refrigerator). It is recommended to verify the variation in time of the concentration of the analyte. The yield of methods for isolation of additives from the polymer matrix needs to be verified by an independent absolute method, analysis of a sample with known... 

Rotational Motion of Molecules Spinning molecules store energy in the form of rotational momentum. Similar to the vibrational modes of storage, for a more complex structure, the molecule has a greater number of rotational modes available. A monatomic species such as helium has no bonds and therefore cannot store energy in this form. 

The exit gas, containing 12-18% NH3, is first cooled by heat exchange with the incoming synthesis gas, then by air or water, and finally by refrigeration, whose temperature depends on the mode of storage. If the gas is to be stored at atmospheric pressure, it must be cooled to —33 °C, ammonia s boiling point. The umeacted synthesis gas is recompressed and recycled into the converter. A large number of innova-...
