Quench Cooler
The Quench Cooler is designed for rapidly cooling the DSC cell to a lower temperature before
initiating programmed heating experiments. The DSC Quench Cooler fits over the standard
DSC cell and has a reservoir into which you can place coolant to cool the cell. The temperature
when using the Quench Cooler is –180 to 550°C. The actual range depends on the coolant (ice
and water, dry ice, or liquid nitrogen).
Before you initiate a heating experiment, you will need to remove the Quench Cooler and put
the enclosure lid back in place.
If the Quench Cooler is used for temperatures
below –100 °C, then helium must be used as the
purge gas.
NOTE: The Quench Cooler cannot be used to
perform a Tzero calibration of the DSC.
Therefore, only T1 heat flow is available when
using the Quench Cooler.
NOTE: The Quench Cooler requires manual
lids and therefore cannot be used with the
Autosampler. The AutoLid is disabled
("parked") during Quench Cooler operation.
Liquid Nitrogen Cooling System (LNCS)
The LNCS (Liquid Nitrogen Cooling System) is a universal
cooling accessory for use with TA Instruments Analyzers. It
can be used with all DSC Q Series models.
The Liquid Nitrogen Cooling System (LNCS) allows auto-
matic and continuous temperature control within the range
of –180°C to 550°C. The LNCS tank is pressurized to deliver
the liquid nitrogen to the heat exchanger, which in turn cools
the cell.
The LNCS (shown here) can be autofilled in your laboratory
using the DSC touch screen or through the instrument con-
trol software. This requires a low pressure 170 kPa gauge
maximum (25 psig) bulk storage tank to be located within
1.8 m (6 feet) of the LNCS. See the
LNCS Getting Started Guide
for further information.
