Some samples contain more than one volatile material, such as nylon resins with large 
amounts of unpolymerized material (Caprolactam).  In these cases, the rate will fall to 
some fixed value when all the moisture has evaporated but while the monomer is still 
evaporating.  The GRAPH display available from the Main Test screen is of great help in 
visualizing these cases.  The rate ending criteria, if set above the rate of monomer 
volatilization, may give the best results. 
 
For TIME, the MAX

®

 4000XL ends the test after a preset time (up to 120 minutes) has 

past. TIME may be useful for conducting sample characterization tests and other 
development purposes.  
 
For TIME or RATE, the MAX

®

 4000XL ends the test after the sample weight loss rate has 

fallen below a preset value or after a preset time.  The TIME or RATE may be useful to 
quickly end a test for a sample that is much wetter than expected and the final result is not 
necessary. 
 
Use the “TEMP THEN …” ending criteria (TEMP

PREDICT, TEMP

RATE, and 

TEMP

TIME OR RATE) to prevent a test from ending before the temperature reaches 

within 2 degrees of the preset test temperature.  Generally, this is not needed. 
 
Use the “TIME THEN RATE” ending criteria (TIME

RATE) to end the test when the 

sample weight loss rate falls below the preset value, after the set time has elapsed.  This 
ending criterion is useful for: 

•

  Samples that take a long time to heat up before evolving moisture (the rate curve 

stays low for a while before rising significantly). 

•

  Samples that have a double peak evolution rate curve.  Use the Time set to extend the 

test past the first evolution rate peak. 

 
The MAX

®

 4000 will end a test after 120 minutes regardless of the selected ending 

criteria.

SAMPLE SIZE OPTIONS 

 

The sample size options are used during 
sample loading to restrict the sample load 
to a desirable amount.  Sample sizes can 
be programmed from 0.2g to 39.9g.  The 
sample window must be at least 

±

0.1g and 

the total of the sample size plus the 
sample window must be less than or equal 
to 40g maximum.  Note:  Samples as small 
as 100mg (or as large as 40g) can be 
tested by using a sample size of 0.2g (or 
39.9g) with a sample window of 0.1g.
