Installation of the Optional Sample Cooler or Thermostat
Using the Sample Cooler or Thermostat in an Infinity II Sampler
Temperature Mode
Temperature control for autosampler thermostats.
Since driver A.02.04, users could decide whether the
temperature of the
thermostats
should be a
control setting or a method parameter
. With the
introduction of Multisamplers, it has been decided that the thermostat should
not be a method parameter for the following reasons:
•
Changing the temperature from method to method changes the ALS
temperature for ALL samples, not only for the one in the current method.
•
The sample temperature can not be directly controlled, only the
temperature of the air stream from the thermostat. If the air stream has the
correct temperature during method execution, it may have been stored at
higher temperatures with previous methods.
As a result, we are now introducing two modes which can be configured in the
dashboard:
•
Constant temperature mode
: this mode uses the control setting for keeping
samples at a fixed temperature. This is the default and recommended for
most customers.
•
Variable temperature mode
: this mode allows changing the temperature as
a method parameter. This mode may be used for degradation experiments
(this solution is not officially recommended by Agilent) or as a workaround
for reporting. Reporting of control parameters will become available with
the CDS and ICF.
