6 PERFORM AN ANALYSIS
n Handling System Components on page11 - 5
In 21CFR11 environments, users are required to login to the Confirm application to start
an analysis. Once the analysis window is opened, manual control is disabled until the
analysis has completed. During analysis, pausing and resuming is allowed, however,
steps cannot be skipped.
An analysis can be performed from either the computer application or directly from the keypad on the
analyzer.
PREPARE AND LOAD A SAMPLE
FOAMPYC METHODS
n About the FoamPyc Module on page1 - 5
FoamPyc Methods are intended to conform to the procedures detailed in ASTM Test Methods
D-6226 and D-3576. Prepare samples according to the methods outlined in these procedures. Once
the sample is prepared and placed into the sample chamber, analysis can begin.
STANDARD METHOD
Samples must be properly prepared to obtain accurate results. Samples must be free of moisture in
order to obtain true sample mass and to avoid the distorting effect of water vapor on the volume
measurement. The following procedures are recommended; however, modifications may be
necessary for some materials:
n Heat-sensitive materials may have to be dried by long-time exposure to silica gel, freeze drying,
etc.
n Materials having a low melting point may be dried using the purge process. In this case, do not
weigh the sample and cup until after the purge and analysis have been completed.
Avoid exposure of the dried sample to atmospheric moisture during each step of the preparation
process. This means weighing as rapidly as possible and installing in the instrument without
unnecessary delay.
